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'.

Answer:
A. Neurotransmitters and depression
Explanation:
The complete question is :
A biological psychologist would be most interested in conducting research on the relationship between:
A. neurotransmitters and depression.
B. skull shape and bone density.
C. self-esteem and popularity.
D. genetics and eye color.
- A biological psychologist is a person who is interested in studying the behavior of human beings and tries to understand the psychological causes underlying the behavior along with the various genetic and chemical factors that affect the behavior.
- It is believed that the genetics and the chemical factors of the brain together affect the psychology of a person and ultimately affect the behavior.
- Thus, they establish a link between the physiological processes and the psychology of a person.
- Therefore, in case a person is suffering from depression which is a psychological problem a biological psychologist would try and understand the chemical changes in the brain and thus would study the neurotransmitters.
