What animals are there to choose from?
Answer:
either one of the two alleles in a diploid individual.
Explanation:
A trait is expressed only when two alleles pair up. Thus, an allele pair during cell division assort independently into two individual alleles so that each gamete receive one of the two allele
For example
During gamete formation XX and XY allele pairs divide to contribute one allele to each gamete respectively.
Thus, XX allele pair will divide to give X gene to both the gamete
And XY pair will divide to give X gene to one gamete and Y gene to other gamete
