What is one advantage of prezygotic isolation over postzygotic isolation?

With prezygotic isolation no energy is lost trying to produce a zygote that is not viable. With postzygotic isolation a viable zygote may be formed and born but it will be sterile and so a lot of energy is expended to nourish and raise an offspring that will not be able to continue the genetic line. Prezygotic isolation is more energy efficient in a sense.

eukarya because is is like alche and b is bacteria and d is animals

explanation:

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
