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).
List the five Hardy-Weinberg conditions. Choose one and explain it using a specific example why the condition is rarely met in nature.
Figure 2, below, shows a set of DNA fingerprints used to identify the father of one child in question. By matching up the genes that appear in the child, can you determine which man is the most likely to be the putative father? Why?
Sexing kittens is always difficult unless the kitten is a calico. Explain why.
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.
If a couple are both rh positive...the man being B+ and the woman is O positive Is it possible for this couple to have a B- child? Also why is it that a B- child can only receive blood from a B- or O- person? If this child ever needs a blood transfusion how come neither one of the parents can donate blood does this mean this chi
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.
Please provide suitable explanation 5- Discuss the mechanisms by which transcription of mRNA can be terminated in prokaryotic cells. 6- Discuss the process under printing the expression of foreign gene in bacterial cell.
1- The genes for both the alpha-and beta-globin chains of hemoglobin contain introns (i.e., they are split genes). How would this fact affect your plans if you wanted to introduce the gene for alpha-globin into a bacterial plasmid and have the bacteria produce alpha-globin? 2- Bacteria and yeast are known not to have prions.
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
