brief answe please

Answer 1

in sexual reproduction, 2 different types of DNA, from both parents, mix to form one unique type of DNA. during fusion, certain characteristics are taken from the male parent and others from the female parent. thus, the new cell develops into a unique offspring which displays characteristics of both parents. e.g. a newborn may have the eyes of its mother but may display its fathers nose, etc.

Answer 2

Embryos of many different kinds of animals like mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart. Many traits of one type of animal appear in the embryo of another type of animal. For example, fish embryos and human embryos both have gill slits. Thus we can show that in case of sexual reproduction, newborn show similarities about characters. We had also given an example here
