A female heterozygous drosophila melanogaster with the x linked genes of singed bristles (sn), crossveinlesss wings (cv), and vermillion eye colour (v) is testcrossed with a singed, crossveinless, vermillion male and the following progeny were obtained: 1 singed, crossveinless, vermillion 3 2 crossveinless, vermilli
A red-bellied male that had a yellow-bellied father mates with a blue-bellied female that had a purple-bellied mother and a blue-bellied father
In Pacific Pooch-Bellied Wrasses, belly color is controlled by a single gene located on the X chromosome (i.e. is sex linked), that can take one of four forms (alleles): Xy = yellow bellied, is dominant to all other alleles; Xb = blue bellied, and Xr = red bellied are incompletely dominant and produce purple-bellied fish when th
Both parents have the brown/blue pair of eyes color genes, and each parent contributes one gene to a child. Assume that if the child has at least one brown gene, that color will dominate and the eyes will be brown. (The actual determination of eye color is somewhat more complicated.) a. List the different possible outcomes
List three uses of genetic recombination in medicine and list three uses of genetic engineering in agriculture.
Postulate why populations in northern climates have gene pools in which most members have the recessive genotype (bb for blue) for eye color, while populations in Africa and South America more often have gene pools with the dominant genotype (B for brown).
Ideas about the influence of heredity and hormones on human behavior are presented with research links to supplement.
Influenza virus causes both epidemics every few years, and pandemics every few decades. This section describes how the changes in the virus are responsible for generating epidemics and pandemics.
Discuss in a brief narrative Mendel's (Gregor Mendel, often called the "father of genetics") principles, how he derived them, and what they mean to the world today.
Eukaryotic cells can divide by mitosis or meiosis. In humans, mitosis produces new cells for growth and repair. And, meiosis produces sex cells (gametes), called sperm and eggs. Changes or mutations in genes in sex cells can be inherited by human offspring. Genetic variation in a population of organisms is good; however, sometim
A. APunnett Square represents a cross (mating) between a male (on the left side) with blood type AB, and a female, (top of square), with blood type A, genotype Ao. Answer the following for the cross represented above. 1. What are the possible blood types for the offspring? 2. What are the ratios or percentages for each poss
Ideas to compare and contrast the influence of heredity and hormones on human behavior are given.
Describe the structure and function of DNA as the molecule of inheritance. I need a better understanding of the below: a. Describe the structure of DNA. b. Discuss how the structure of DNA allows it to serve as the basis for inheritance. c. Examine how meiosis allows DNA to be divided into gametes. d. Describe how
From these 3 alleles, there are 4 blood types (phenotypes): A, B, AB, and O, and there are six genotypes: AA, AO, BB, BO, AB, or OO. This is an example of co-dominance in which both A and B alleles are co-dominant to each other. Blood types can be used in forensics to determine if blood is from the victim or criminal. Blood
Biotechnology allows us to use living organisms or their processes for human needs or purposes. This current topic includes such examples as cloning, stem cells (adult, umbilical cord, and embryonic), DNA fingerprinting, biological warfare, bioremediation, genetically modified organisms, vaccines, and transgenic plants and anim
1.What unique ability do DNA molecules have? Why is this ability so important? 2.What are the similarities and differences in DNA and RNA? 3.What are the respective functions in general and in protein systhesis? 4.What are the various factors that might damage genes? 5.Explain the process of mitosis along with its variou
Part 1: Genetics Problem- Human Blood Types Mendel is the father of modern genetics, but there are some genetic characteristics that cannot be explained by simple Mendelian genetics. Such is the case with the human blood types in which there are 3 alleles for the same gene, A B, and o. A parent can pass allele A, B, or o to th
I am having trouble with these few sample problems. I really do not understand the concept of Mendel's ideas. Can someone please elaborate? Please see attached file.
Please help create an outline based on the given lecture slides (see attachment).
I need to compare and contrast the influence of heredity and hormones on human behavior.
I am having a very hard time trying to figure this out. I need someone to explain to me how to go about this...showing an explaining their work. My goal is to gain assistance understanding this for I need to grasp this, so please show me HOW! In a population of monkeys, there are two types of coat color that follow simple M
In Drosophila, vestigial (partial formed) wings (vg) are recessive to normal long wings (vg+), and the gene for this trait is autosomal.
In Drosophila, vestigial (partial formed) wings (vg) are recessive to normal long wings (vg+), and the gene for this trait is autosomal. The gene for the white eye trait is on the X chromosome. Suppose a homozygous white-eyed, long-winged female fly is crossed with a homozygous red-eyed, vestigial-winged male. A. What will be t
In the cross AaBbCcDd x aaBbccDd, each of the 4 genes is inherited independently from the other 3 genes
In the cross AaBbCcDd x aaBbccDd, each of the 4 genes is inherited independently from the other 3 genes (the genes are all unlinked), and each of the four genes exhibits complete dominance. a.What is the probability that an individual offspring will be phenotypically identical to the first parent? b.What is the probability t
In cattle, hornless is dominant to horned, red coat color is incompletely dominant to white, where the heterzygote has a color called roan.
In cattle, hornless is dominant to horned, red coat color is incompletely dominant to white, where the heterzygote has a color called roan. What would the parental genotypes be in the following crosses? What woyld the genotypic and phenotypic ratios of the F1 be in the crosses? a. heterozygous hornless red bull X horned ro
A researcher studied six independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower. From the cross (P1) R
Dear sir, I have got a query about how genes are transmitted from parents to kids. The situation is: I am blue eyed, my mother is green eyed and my dad is brown eyed. This far so good, no problems: I thought,my mum is green(G)-blue(b) and my dad is brown(B)-blue, so I had 1 out of 4 of turning out being blue. It's norma
Explain why the process of mitosis and meiosis are both important to a living organism. When would an organism need to undergo the process of mitosis? Meisis? What would happen if meiosis did not occur?
I'm writing a report on cells which overexpress HER-2. The report consists of 5 mini reports and is for a Biomedical Techniques module I am doing. Part of the report is on the monolayer culture and passage of cells and also requires calculations for multiplication rate, doubling time etc (have done these) I have two main que
I am researching the structure of DNA, but can not understand how meiosis allows DNA to be divided into gametes.
What is the structure and function of DNA? How the structure of DNA allows it to serve as the basis for inheritance.
How did Mendel's approach to answering scientific questions differ from that of his contemporaries? How did his novel approach contribute to his success in describing how traits are inherited? What advantages did he enjoy by choosing to study the garden pea?
