A- Pointy ears
B- Round ears
C- Ppinty or round ears

C. They can have pointy or round ears

Explanation:

Alleles, two versions of a gene an individual can receive from its parents, can be dominant or recessive. Depending on the combination of alleles, an individual can have different traits.

This is what the Punnett square will look like in the given case:

    Y       y

Y  YY    Yy

y   Yy    yy

Y is the dominant allele, and y is the recessive one. If both alleles are dominant, or one is dominant and the other recessive, the dominant allele will be expressed. The recessive allele will be expressed only when both alleles are recessive.

The babies with YY and Yy genotype will have pointy ears, and babies with yy will have round ears.

This is why option C is correct.

the fossil record provides evidence of a common ancestor to many species.
