Question that is related to Biology?

Alleles are different forms of one gene. For example, there could be a flower that had a gene for the flower color. There could be an allele that resulted in white flowers and an allele that resulted in yellow flowers. For every gene, an organism inherits one allele from its mother and one from its father. So, for every gene, we each have two alleles. In the case of the flower, it could inherit yellow alleles from both its parents, white alleles from both its parents, or a different allele from each. An individual which has two of the same alleles (both white alleles or both yellow alleles for the flower) is called heterozygous for that gene while an individual that has two different alleles (a yellow allele and a white allele) is called zygous for that gene. Keep in mind that there can be more than two alleles for a trait - I was just using that example for simplicity's sake!
