:) please help!!! Briefly describe the traits seen in each genotype:
kolezko [41]
<h2>Answer 1 with Explanation</h2>

Homozygous dominant- It can be an organism if it carries two copies of the same dominant allele as homozygous which clearly means that the organism has a pair of models that is the corresponding allele for a gene. This gene originally belongs to a particular gene that has same alleles on both homologous chromosomes. It is assigned to by capital (XX) in the subjective terminology.

<h2>Answer 2 with Explanation</h2>

Heterozygous dominant is an organism that carries two different alleles of a gene. Though this is originally is referred to as (Tt). Heterozygous means that an organism has two different varieties of the gene within the system of dominant, the protein each makes is slightly different from one another and the organism has both tall and short versions within the dominant.

<h2>Answer 3 with Explanation</h2>

A recessive gene is one that has to be homozygous to have an effect on the plant's or animal's traits that is naturally in process. This process of homozygous is is referred to by the lower case (xx).
