Answer:A

Explanation:

The meaning of evolution-the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

Alexxx [7]

Answer:

3 black gebrils have straight tails

Explanation:

Given -

First group of true breeding gebrils have black fur and curly tails

Second group of true breeding gebrils have yellow fur and straight tails

After the F1 generation, all the offspring would have black fur and curly tail

This means black fur is dominant over yellow fur and curly tail is dominant over straight tails

Let "Black fur" be represented by "B" and "yellow fur" be represented by "b"

Let curly tail be represented by "C" and straight tail be represented by "c"

Then parents genotype for F1 generation would be "BBCC" and "bbcc"

and genotype of first generation offspring would be "BbCc"

BbCc
