Tricky question I am not sure how to answer this

uwsp canvas - Search O Thought OQuestion 2 uwstp.instructure.com/courses/479599/assignments/4335506 A mule is the offspring of a horse and a donkey. A donkey sperm contains 31 chromosomes and a horse egg contains 32 chromosomes, so the zygote (1-cell embryo) contains a total of 63 chromosomes. The zygote develops normally, as the combined set of chromosomes is not a problem in mitosis. However, a mule is sterile; meiosis (and, therefore, gamete production) cannot occur normally in the gonads. Explain why mitosis is normal in cells containing both horse and donkey chromosomes, but the mixed set of chromosomes interferes with meiosis.
