Mr Mwape and his wife are both heterozygous tall and brown and have 3 children who are tall and brown and one child who is short
love history [14]

We can explain Mr Mwape that variation in his children through Mendel’s law.

Reason why three children tall and brown one of MR Mwape was short and dark is: -

• Skin color and height is controlled by a lot of genes and every human gets one set of genes from their mother and the other set of genes from their father.

• Now imagine these genes are denoted as ‘T’ for tall and ‘B’ for brown and ‘t’ for short ‘b’ brown. We can assume that MR Mwape and his wife having genotype TtBb.

• During the process of gene segregation and assortment, the majority percentage of children got the heterogenous dominant genotype, which is ‘TtBb’, overlapping the effect of gene ‘t’ and ‘b’. While another child got a homogenous recessive genotype ‘ttbb’ from both the parents, hence the genotype is prominently shown in the fourth child and not in other as gene 't' and 'b' were dominated by genes 'T' and 'B'.
