E. None of the above because I’m smart
What are u talking about my guy
Explanation:
Mutation, together with recombination of existing alleles provides the diversity which is the raw material for natural selection and evolution. ... Gene flow can accelerate the spread of successful alleles or reduce differences between populations.
Hitchhicker's thumb is a condition in which a person is able to bend his thumb backwards. This trait can be seen in many people but the condition is recessive, which means a person needs two alleles for hitchhiker's thumb to have this particular characteristics. The gene for straight thumb is commonly indicated by T while that for hitch hicker's thumb is indicated by t.
Let's see what will happen if a person heterozygous for hitchhiker's thumb marries a woman who is also heterozygous for hitchhiker's thumb.
P1: Tt X Tt
Gametes: t T : t T
Offsping : TT : Tt : tT : tt
TT : 25 % : Straight thumb
Tt + tT : 50% : Straight thumb
tt : 25% : Hitch hicker's thumb
Therefore, there are 25 % chances that their offspring will have Hitch hicker's thumb and 75 % chances that they will have straight thumb.
Hope it help!
