Homework Answers
Answer is A_b and a_B
A-b and a_B represent recombinant gametes.
A_B and a_b denotes parental genotypes.
A_A and B_B are homozygous ,A_a and B_b are heterozygous.

Amounts of which of the components of cell cycle regulation vary with cell cycle phase? Cyclin-dependent kinases Cyclins Checkpoints Kinetochores The synaptonemal complex forms to facilitate pairing of homologous chromosomes during prophase of mitosis and meiosis. prophase of meiosis I and II. c. prophase of meiosis I only. d. all stages of meiosis. Mendel’s Second Law of Independent Assortment refers to the separation of two identical alleles of the same gene. two different alleles of the same gene. alleles...

For these questions, you are using the A, B, and O to represent the alleles in this example. The ABO blood system works in a Mendelian fashion, but has 3 possible alleles at one locus (A, B, and O alleles). Each person can have only 2 of those alleles in their genotype. A and B are both dominant (and so can be co-dominant), and O is recessive to both A and B. So, for example, if you have B blood...

Consider a human germ cell undergoing normal meiosis (with only chromosome 23 shown). The dark blue represents the maternal chromosome and the light blue represents the paternal chromosome. Which of the 6 possible gamete types would you observe following the completion of meiosis (Choose all that apply)? 3. Consider the same human germ cell. If a single chromosome nondisjunction event occurs during meiosis I, which gamete types will you expect following the completion of meiosis (Choose all that apply)? 4....

1) An organism has 2n = 6 chromosomes with alleles A B / a b on the chromosome 1 homologous pair, alleles D / d on the chromosome 2 homologous pair, alleles E F / e f on the chromosome 3 homologous pair. Show two different ways that chromosomes could align at the metaphase plate during Meiosis I (show the chromosomes and alleles). Assume no crossing over. How many combinations of chromosomes are possible in the gametes? Please show me...

1) Consider a single germ cell with the genotype A/a;B/b undergoing meiosis. Which of the following are possible genotypes for the set of four gametes resulting from meiosis of this single germ cell? (assume that there is NOT any nondisjunction) A, a, B, b Aa, Aa, Bb, Bb AB, Ab, aB, ab Ab, Ab, aB, aB aa, AA, BB, bb 2) From true-breeding stocks, a female fly with no eyes (mutation in eyeless (ey) gene) and no wings (mutation in...

2. A diploid cell contains two pairs of chromosomes, which we will call 1 and 2. Assume chromosome! is clearly larger than chromosome 2. Each chromosome pair contains a maternal and a paternal member (e.g. 1 and 1 & 2 and 2"). An allele called G is localized to 1" whereas an allele called g is on chromosome 1P. Allele R is localized to 2m whereas alleler is localized to 2. Using these designations and clearly drawn and labeled chromosomes,...

A cross between individuals with genotypes a+a b+b x aa bb produces the following progeny (this is a symbolization system that is often used in microorganisms and Drosophila: where instead of Aand athey use a+and a): a+a b+b 83 a+a bb 21 aa b+b 19 aa bb 77 Does the evidence indicate that these two genes are linked? Explain (what do you expect if they are not linked?). If so what is the map distance between aand b? (show your wok) Are the alleles...

2. Short tandem repeat polymorphisms (STRPs) are genetic markers that have multiple alleles per locus in the population. Since there are more than 2 alleles for a STRP, we have to use numbers rather than A/a or +/- to indicate their identities. The following pedigree corresponds to the genotype table below. The order of alleles listed for each genotype does not indicate anything about haplotype (e.g. "1,2" could mean 1 is on the maternal chromosome and 2 is on the...
