Answer:
The answer is A muscilar dystrophy
Explanation:
Progressive muscular dystrophy, which shows the patient by the symptoms that were manifested from three years of age and who started with walking on his toes and the difficulty in raising the legs accompanied by progressive weakness confirm this diagnosis worsening his clinical manifestation at nine years of age, where there is a marked skeletal muscle deformity that makes the use of a wheelchair necessary. we can discard miestemia gravis and multiple scoliosis because they are not pathologies of this age group, polio in turn is a contagious infectious disease that is eradicated in much of the world, mostly in developed countries thanks to the vaccine.

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'.
