Answer 1

QUESTION

Assume that in mice, B = Black fur , b = brown fur.

if a heterozygous black mouse mates with a homozygous brown mouse , what percent of their offspring will have black fur?

ANSWER

genotype of heterozygous black mouse = Bb

genotype of homozygous brown mouse = bb

${ \boxed{ \tt{ \red{ \ </strong><strong>♂</strong><strong>/</strong><strong> ♀</strong><strong>\: \: \: \: \: \: \: </strong><strong>B</strong><strong> \: \: \: \: \: \: \: \: \: \: \: \: \: b \: \: \: }}}} \\{ \boxed { \tt{ \red{ \: \: b \: \: \: \: \: { \green{ \tt{</strong><strong>B</strong><strong>b \: \: \: \: \: \: \: \: \: \: \: bb}}}}}}} \\ { \boxed{ \tt{ \red{ \: \: b \: \:{ \green{ \tt{ \: \: \: </strong><strong>B</strong><strong>b \: \: \: \: \: \: \: \: \: \: \: \: bb}}} }}}}$

two heterozygous black mouse with genotype Bb

will be formed and there percentage is 50 % of the total offsprings.

Answer 2

If a heterozygote black mouse mates with a homozygous brown mouse , 0.5 is their offspring that will have black fur.
