CHAPTER 1 : HERIDITY AND GENETICS

CO-DOMINANCE

This is a situation whereby a single characteristic or threat is controlled by 2 or more allele and none of the allele is ressecive to the other

That is the allele always expressed themselves equally. The human blood gray is called by 3 allele we have A,B, and O the allele A and B codominant that is they express thier

r selves equally when presented in an individual allele O is recessive to A and B this human present or have blood group which

Example 1 The seed resulting from a cross between white and alusite flower and a red and alusite flower gave a generation of pink flowers explain with the aaid of appropriate symbols and diagram what do you expect the next generation of flowers to be if in the pink were to be pollonated

Solution

Let the allele white= WW

Let allele alusite= RR

Parental phenotype= WW, RR
