On crossing of horse (64 chromosomes) and zebra (46 chromosomes) produces offspring(rare case) that are,
Open in App
Solution
The correct option is D Sterile, with 55 chromosomes
On crossing horse with a deploid number of chromosome (64) and zebra with diploid chromosome number (46). Gametes formed by these individuals will be haploid i.e., horse (n =32) and in zebra( n=23). Thus the cross between these two will yield an offspring with 2n= 55. Thus, the correct answer is option D.
