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 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 (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.
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?
1. Why do gene frequencies in a population change? Why don't they stay the same from one generation to the next? Explain how the processes of mutation, crossover, and natural selection can provide an answer to these questions. Support your response with cited documentation where appropriate.
How have transposable elements contributed to the evolution of the eukaryote genome? Discuss the different types of pseudogenes found in eukaryote genomes. Discuss the phenomenon of gene and genome duplications and how they have contributed to the evolution of the eukaryote genome. What fates can befall the products of

Forensic Science - The O.J. Simpson trial highlighted the importance of proper evidence handling and sample processing.
Question 1: The O.J. Simpson trial highlighted the importance of proper evidence handling and sample processing. Despite overwhelming DNA evidence connecting Simpson to the double murder, the jury in his criminal trial acquitted him. Do you agree or disagree with their verdict? Why? Question 2: The sex of an individual can

A) At a particular autosomal STR locus a man has alleles 5 and 8 and his wife has alleles 7and 4. What are all possible allele combinations for their offspring? B) One of their children is typed for this loci and has alleles 7 and 7. Can these two individuals be the parents? Why or why not? C) Another of their children is
A group of 6 bodies is found buried in the woods, three adult males, one adult female, and two children. They are thought to include a missing family (2 parents and 2 children). DNA is extracted from the skeletal remains and analyzed for two STR markers using PCR. In the results below, the numbers indicate the number of tandem r
A botanist interested in the chemical reactions whereby plants capture light energy from the sun decided to dissect this process genetically. She decided that leaf fluorescence would be a useful mutant phenotype to select because it would show something wrong with the process whereby electrons are transferred from chlorophyll. T
