Howmany chromosomes are in a chicken zygote

How many chromosomes does a chicken zygote have

78

Explanation:

Chickens have 78 chromosomes. They inherit 39 from each parent, therefore a zygote (which is made up of an egg and a sperm, each a haploid gamete with 39 chromosomes) will have 78 chromosomes.

This is more than humans: we have 46 chromosomes, as we inherit 23 from each parent.
