Below is a primary spermatocyte in metaphase I of meiosis. The chromosomes have already replicated and lined up as shown along the metaphase plate for this particular meiotic event. In each case, alleles of a gene are shown for each chromosome (A/a and F/f). What are the possible genotypes of the sperm once both phases of meiosis are complete? A Alaa XX ff 818 Af, aF AA, FF, aa, ff Aa, Ff AF, af AF, Af, aF, af

Match the stage of meiosis with the image.

Which meiotic division(s) reduce(s) chromosome number (i.e., meiosis I, meiosis II, or both)? Explain your answer. Edit View Insert Format: Toold Tabl

Caspar's genotype is HhRr.  These genes are located on the same chromosome,  so the haplotype is: H  R h   r   For this problem, there is no recombination between the genes. Knowing this, draw for yourself how these chromosomes should align and separate during meiosis.  Now, from the choices below, which gamete would represents a nondisjunction event in meiosis II?   hr HhRr Hhr HHRR

What type of gametes can be produced by simple non-disjunction of the sex chromosomes in a human male?  Simple non-disjunction means that non-disjunction occurs in meiosis I or meiosis II, but not in both meiosis I and meiosis II. Choose all answers that are correct Group of answer choices 22, 0 24, YY 25, XXY 23, XX 23, XY 25, XXX 24, XY 24, XX

In a germline cell of genotype Ff Qq where genes F and Q are on different chromosomes, capital and lowercase letters represent alternate alleles (versions or variants) of each gene. If this cell undergoes normal meiosis to produce sperm, what are the possible sperm genotypes? FQ, fq, Fq, fQ Ff, Qq, FQ, fq, Fq, fQ O Ff, Ff, Qq, Qq O F, f, Q, q

If a male has genotype Aa Bb Cc Dd, what proportion of his sperm cells are expected to have genotype A B C D? Type your answer as a fraction, with no spaces.
