Question

Do the results of this cross fit with the expected.J.J. p / n at o. (5) In humans, right-handedness is dominant to left-handedness (RR, Rr right handed and rr- left handed) and normal skin pigmentation is dominant to albino (AA, Aa normal and aa- albino). A completely heterozy gous man (RrAa) marries a right-handed, albino woman (Rraa) a. what is the probability that they will produce three girls (no boys)? b. what is the probability that they will produce a left-handed girl? What is the probability that they will produce a girl that is left-handed and albino? c.

Explanation / Answer

a)as event of having a girl is independent ad probability of having a girl =1/2 ; hence

P(having 3 girls) =(1/2)*(1/2)*(1/2)=1/8

b)

P(produce a left handed girl)=P(girl)*P(from mother r trait and from father r trait)=(1/2)*(1/2)*(1/2)=1/8

c)

P(produce a lgirl tha is eft handed and albino)

=P(girl)*P(from mother r trait and from father r trait)*P(from father a trailt and from mother a trailt)

=(1/2)*(1/2)*(1/2)*(1/2)*(1) =1/16
