Questions 1. Based on random and independent assortment alone, how many genetically distinct gametes can be produced by meiosis of a diploid (2n) cell that has 4 chromosomes? 2. Based on random and independent assortment alone, how many genetically distinct gametes can be produced by meiosis of a diploid (2n) cell that has 6 chromosomes?

1. A diploid organism produces four gametes from one parent cell through the process of meiosis. Two gametes are found to have 5 chromosomes, one gamete is found to have 6 chromosomes and one gamete is found to have 4 chromosomes. A) Is this the expected number of chromosomes that would be found in each gamete following a normal cycle of meiosis? If yes, explain why. If no, explain why not and describe how the gamete situation described above occurred. B) Determine the number of homologous chromosome pairs that the original parent cell contained, before meiosis began. Explain how you determined this value.

Consider a diploid cell that contains three pairs of chromosomes, designated aa, bb, and cc. each pair contains a maternal and paternal member assume that during meiosis i, none of the c chromosomes disjoin at metaphase, but they separate into dyads (instead of monads) during meiosis ii. each resultant gamete participated in fertilization with a normal haploid gamete. what are the possibilities for the number of c chromosomes present in the resulting gametes
