Organisms don’t all reproduce the same way. however, by comparing the cells embryos mode of reproduction of these organisms, many similarities between them are revealed. these similarities suggest that they’re evolutionarily physically poorly linked. this type of study is called developmental biology.

-Embryos

-Evolutionary

Organisms don’t all reproduce the same way. However, by comparing the cells embryos of these organisms, many similarities between them are revealed.

These similarities suggest that they’re evolutionary linked. This type of study is called developmental biology.

Explanation;The study of embryos is called embryology.Embryos of different animals such as mammals, birds, fish, reptiles etc. look alike that is they are very similar. Many traits of one type of animal appear in the embryo of another type of animal.Similarity in embryos among animals shows commonality in terms of evolutionary relationship, implying presence of common ancestry.

The offspring will be blood type aa, bb, ab and oo or i

Where are they though?
