Q1. Suppose that the allele controlling brown eyes (B) is dominant over those controlling blue eyes (b) in human beings. (In actuality, eye colour in humans is an example of multigene inheritance, which is much more complex than this.) A blue-eyed man marries a brown-eyed woman; and they have six children, all brown-eyed. What is the most likely genotype of the father? Mother?

If the seventh child had blue eyes, what could you end about the parent’s genotypes?

Q2. Explain the process of protein synthesis beginning from the dna sequence TCGAGAATCTCGATT to the amino acid sequence. Include transcription, translation, mRNA, tRNA in explanation.
