Fossils can show structural similarities and differences in organisms over time revealing the vast diversity of life forms that have and continue to exist on Earth.
Comparisons between living organisms and fossils also allow scientists to make inferences about the lines of descent.
Answer:
D
Explanation:
Homozygous mean a pair of alleles that are the same. Hence the root word homo- which means same. If the alleles were different, we would call this pairing a heterozygous pair, with the root word hetero- meaning different. An example of a homozygous pair would be AA, two dominant allele, or aa, two recessive alleles, while a heterozygous pair would be Aa, one dominant and one recessive allele.
