| A cell undergoing meiosis has four pairs of homologous chromosomes. How many different combinations of maternal and paternal chromosomes are possible within the daughter cells that form? (Do not consider crossing over in your answer.) | |||||||||

Homework Answers
Number of chromosome combinations in crossing over = 2^n, where n is haploid chromosome number
Here, n = 4
2n = 8
Number of chromosome combinations = 2^4 = 16
Answer is 16.

Consider a diploid cell that contains 6 pairs of chromosomes. Each pair includes a maternal and a paternal member (for example: Am Ap(one pair) or Am Ap Bm Bp (two pairs). How many different combinations of chromatids are possible during the early phases of anaphase in meiosis II? Enter you answer as a whole number: ______[a]__________.
BIOLOGY - Independent assortment and genetic variation
Consider a diploid cell where 2n = 6. During metaphase I of meiosis, as the pairs of homologous chromosomes line up on the metaphase plate, each pair may orient with its maternal or paternal homolog closer to a given pole. There are four equally probable arrangements of the homologous pairs at metaphase I. (Note that this problem assumes that no crossing over has occurred.)The cells below show the eight possible combinations of chromosomes that the daughter cells of meiosis II...
