PP and Pp
Explanation:
The dominant allele "overpowers" the recessive allele, therefore that trait shows. In this case, it is the polled allele. Therefore, the heterozygous pair works. Also, the homozygous pair with only the dominant allele (polled) will of course work since that is the only gene.
The answer is genetic variations. In addition, Genetic variation means that biological systems in which individuals and populations are different over space. In a genetic variation, the genes of organisms in inhabitants change. The Gene alleles control separate traits that can be handed on from parents to offspring. The gene variation is significant to the procedure of natural selection in which the genetic variations that stand up in a population occur by chance but the process of natural selection does not.
A fossil record can be used to determine many things such as Earth's age, past history, how long ago the fossil was once alive, the cause of death, etc.
