Answer :
Final answer:
The terms homozygous dominant, heterozygous, and homozygous recessive describe the genetic makeup of an organism regarding a specific trait. WW represents a homozygous dominant genotype, ww represents a homozygous recessive, and Ww represents a heterozygous genotype. These concepts are pivotal in genetics for predicting trait inheritance.
Explanation:
The terms homozygous dominant, heterozygous, and homozygous recessive refer to the types of genetic combinations a person or organism can have. If an individual possesses two identical alleles for a trait that are both dominant, such as 'WW', they are considered homozygous dominant.
When an individual has two identical alleles that are recessive, like 'ww', they are described as homozygous recessive. On the other hand, if one allele is dominant and the other is recessive, as in 'Ww', this is known as heterozygous.
In the context of codominance, both alleles express their traits simultaneously in a phenotype. For example, in the MN blood group, individuals can express the M, N, or both antigens on their red blood cells, exhibiting the codominant inheritance pattern.
