Homozygous or purebred
Alleles
recessive
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
Their offspring will have dominant genes. However, if these offspring have offspring with an amimal with recessive genes, the recessive genes will show up.
Even with the same genotype for a trait, differences in how genes are expressed (phenotype) can occur due to environmental factors or epigenetic changes. These factors can influence gene activity and protein production, leading to variation in the trait even with the same underlying genetic information. Additionally, genetic interactions with other genes or modifier genes can also contribute to differences in how a trait is expressed.
homozygous or 2 dominant or 2 recessive.
A dominant trait is expressed when two different genes for the same trait are present.
