The gene for red hair is recessive to the gene for black hair. What will be the hair colour of a child if he inherits a gene for red colour from his mother and a gene for black hair from his father? Express with the help of flow chart.

Certainly, I can describe the possible hair color outcome using a flow chart. Let’s represent the genes for red hair with ‘r’ (recessive) and for black hair with ‘R’ (dominant).
In this flow chart:
1) The mother has the genotype ‘rr’ (red hair) because red hair is a recessive trait.
2) The father has the genotype ‘RR’ (black hair) because black hair is a dominant trait.
3) Each parent produces gametes (sperm and egg) with one copy of their genetic material.
4) During fertilization, the offspring inherits one gene for hair color from each parent.
5) The child inherits one ‘r’ gene from the mother (red hair) and one ‘R’ gene from the father (black hair).
6) The genotype of the child is ‘Rr’.
7) Since black hair (R) is dominant over red hair (r), the child will express the dominant trait and have black hair.
Therefore, the hair color of the child, in this case, will be black.
