The gene for red hair is recessive to the gene for black coloUr
What will be the hair colour of the child if he inherits a gene for red colour from his mother and a gene for black colour from his father?

Dear student,
Assuming the father is with genotype (BB) and the mother is with genotype (bb), the monohybrid cross can be depicted as follows:
Parents : BB × bb
(Black) (Red)
Gametes : B,B b,b
F1 Generation :
F2 Generation : Bb(Black) × Bb(Black) [selfing]
Similarly, you can try out the cross between heterozygous genotype for black (Bb) of the father and homozygous recessive genotype of the mother (bb).
If you find any problem, you can get back to us.
Nice attempt by Aravindram. keep posting!!!
