A gene pair that consists of 2 dominant or 2 recessive alleles is considered homozygous dominant or homozygous recessive.
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
homozygous
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
Homozygous Dominant or Homozygous Recessive, accordingly.
Homozygous
The recessive allele.
Dominant and Recessive Alleles Diploid organisms typically have two alleles for a trait. When allele pairs are the same, they are homozygous. When the alleles of a pair are heterozygous, the phenotype of one trait may be dominant and the other recessive.
Incomplete dominant alleles.
Every gene has a dominant and recessive allele, homozygous is just when a gene has either two dominant alleles or two recessive alleles.
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
