Alleles are defined as the DNA sequence in which the various forms of genes are defined, an example that can be given is the Tyr gene that has two which represent fat and skinny: TT (fat), Tt (fat) , tt (skinny).
The TT allele is homozygous dominant, the Tt allele where it is heterozygous dominant and tt is the homozygous recessive. This means that inheritance is defined by an autosomal dominant, autosomal recessive or incomplete version.
The inheritance pattern of these traits will be independent. However, it will depend on the factor that which trait is dominant or recessive. It might also show incomplete dominance.
The different genotypes that organisms of this population might have are aa, ab, ac, bb, bc , cc. If neither of the alleles are completely dominant over the other, then incomplete dominance might exist for such genes.
In meiosis, chromatids are made to exchange their genetic material during Prophase to allow the formation of offspring that are genetically different from their parents.
The process of exchange is called CROSSING OVER. And it occurs through a contact point known as Chiasma.
