In human beings...?

Question

In human beings, the alleles for for the brown eyes is the dominant (B) over blue eyes(b). Suppose a blue-eyed man marries a brown-eyed woman whose father was blue-eyed. What proportion of their children would you predict will have blue eyes?

Answer 1

1/2

Father = bb (as blue eyed)
Mother = Bb ( as her father was blue eyed, must have one b allele)

therefore,1/2 the children will be Bb (brown eyed) and half bb (blue eyed)

Answer 2

You have to take into account all four grandparents. If two were brown eyed and two were blue then it's a 50-50 chance. If three were brown and one blue then 75/25 in favor of brown. But that's just the odds. Eye color and hair color are some of the traits that cannot actually be determined until the two different DNA's from the parents combine to form a whole new one.

Answer 3

yes it was a war crime. some may think not but the whole idea of using nukes as weapons was wrong. it was not dropped to end the war and save lives. it was dropped to kill . it was too show the rest of the world the power of the USA and to instill fear and horror in the world population of the Almighty america. if as some put it "it was their own fault." what crime against the US did the people of bikini atoll commit against the US . they were removed from their home so the Us could test other bombs. it destroyed the islands. then they were left to starve and die of radiation poisoning till some charitable organization rescued them. this piss the Us government off beaus they were counting on them all perishing so they could gather info on the effects. what crime did the nearby native american indians commit to deserve to be irritate by the trinity test. many died from cancer. the Us a irritate every single person alive in the 40s and 50s on this planet with their test. why do you dumbbells think there is more cancer killing people since the 1940s than before wwi that question was a good one. it proved by some of the answers just how some lack a shred of common sense or compassion or that they posses a conscious. "well every body else was doing it so it was okay and not a crime." right?

Answer 4

1/2 blue 1/2 brown

Answer 5

it also depends on the none dominant part of gene in which everyone has.ie. a person has brown eyed appearance may have a gene of blue eyes.

B=brown
b=b
.......B B
b Bb Bb
b Bb Bb

if one parent is BB, one is bb then the
probablity of having blue eyes is 0%


........B b
b Bb bb

b Bb bb

if one parent has Bb, and another has bb,
then the chance is 50%

Answer 6

50/50

blue eye man = bb
brown eye woman = bB <-- father = bb, therefore she must have B from mother and b from father..

kids = Bb, bb, Bb,bb = 50/50

Answer 7

depends on how many children they have. also you need to give info about the eye colors of his parents and the eye color of the female's mother.

Answer 8

bb and Bb
Bb Bb bb bb it would be a 50 50 chance
