What is the genetic allele that masks the others if both are present

DOMINANT

Allele is the alternative form of same gene. Genes are expressed by phenotype which is the physical characteristics made by genotype and these are observable and dectectable. Another form of allele is the recessive one. This is the allele that is being masked in the phenotype if there is the presence of a dominant allele. All of these falls on genetics which is the study of structure and action , patterns of heredity. This usually use gene as the unit of inheritance and occurs in a location on the chromosome.

the largest of all the ecosystems, oceans are very large bodies of water that dominate the Earth's surface. Like ponds and lakes, the ocean regions are separated into separate zones: intertidal, pelagic, abyssal, and benthic. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land. The intertidal zone is where the ocean meets the land — sometimes it is submerged and at other times exposed, as waves and

Explanation:

They have excellent eyesight, and when one giraffe stares, for example, at a lion a kilometre away, the others look in that direction too. Giraffes live up to 26 years in the wild and slightly longer in captivity.
