Question

A primary spermatocyte has the genotype DdEe. These genes assort independently at Meiosis I. Show the chromosomes containing these genes at Metaphase I, Telophase I and Telophase II using diagrams. Diagrams must be clearly labelled and show metacentric chromosomes undergoing meiosis.                                                                                                         (8 x ½ = 4)

 

Answer 1

Metacentric chromosome:

The chromosome has a centromere at its center.

Genes that undergo independent assortment during meiosis are represented clearly in the below pictures.
