Homework Statement
If we follow meiosis in a diploid heterozygote, the two alleles are, following the first cell division,
a. no longer together in one cell
b. together on a chromatid
c. present only as mutants
d. blended into a new mix
e. chromatids
Homework Equations
Not applicable?
The Attempt at a Solution
Is the correct choice a. no longer together in one cell? For example, let’s say there is a chromosome with B/B on it. (Each B is on a chromatid). Another chromosome has b/b (each b is on separate chromatid) on it. This homologous pairs lines up on the equatorial plate. After anaphase one daughter cell will house chromosome b/b and the other will house B/B?
Homework Statement
If a pair of chromosomes at metaphase I contain the alleles A and A in one chromosome and a and a in the other chromosome, the first daughter cells will contain
a. either a and a or A and A
b. either A and a or a and A
c. A and a and A and a
d. AB, Ab, aB, and ab
e. a and z
Homework Equations
Not applicable?
The Attempt at a Solution
Is the correct answer a. either a and a or A and A? At the end of the first division in telophase, one daughter cell will have a chromosome with A/A on it and the other daughter cell will have a chromosome with a/a on it?
Thanks.
