A trait produced from two alleles that are alike is called homozygous. Homozygous alleles are identical forms of a gene and can be either dominant or recessive. Homozygous dominant means having two dominant alleles, while homozygous recessive means having two recessive alleles for a particular trait.
Actually, gene pairs can consist of two dominant alleles, two recessive alleles, or one dominant and one recessive allele. The combination of alleles in a gene pair determines the specific trait expressed by an individual.
Having a gene pair with two dominant alleles means that both alleles are expressing themselves over the recessive alleles, leading to a dominant trait. Conversely, having two recessive alleles means that the trait will be recessive. This situation is known as homozygous dominant and homozygous recessive, respectively.
Alleles that have an effect on an organism's phenotype are called dominant alleles. Dominant alleles mask the effects of recessive alleles in heterozygous individuals, resulting in the dominant allele's phenotype being expressed.

Homozygous
Dominant.
When the alleles present for a trait are the same, the genes are called homozygous. This means that both alleles for a particular gene are identical. Homozygous individuals can have either two dominant alleles (homozygous dominant) or two recessive alleles (homozygous recessive).
A trait produced from two alleles that are alike is called homozygous. Homozygous alleles are identical forms of a gene and can be either dominant or recessive. Homozygous dominant means having two dominant alleles, while homozygous recessive means having two recessive alleles for a particular trait.
Actually, gene pairs can consist of two dominant alleles, two recessive alleles, or one dominant and one recessive allele. The combination of alleles in a gene pair determines the specific trait expressed by an individual.
The two terms for having matching alleles for a certain trait are "homozygous dominant" (two dominant alleles) and "homozygous recessive" (two recessive alleles).
wha- dominant? alleles?
Having a gene pair with two dominant alleles means that both alleles are expressing themselves over the recessive alleles, leading to a dominant trait. Conversely, having two recessive alleles means that the trait will be recessive. This situation is known as homozygous dominant and homozygous recessive, respectively.
Capital letters usually denote dominant alleles. Therefore QQ genotype would contain two dominant alleles for the Q genotype.
A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
Homozygous Dominant or Homozygous Recessive, accordingly.
If two alleles are dominant, the phenotypes will reflect the dominant traits associated with each allele. Both alleles will be expressed in the phenotype, resulting in a phenotype that shows the dominant characteristics of both alleles.
