In mice, black coat colour (allele B) is dominant to brown coat colour (allele b). The offspring of a cross between a black mouse (BB) and a brown mouse (bb) were allowed to interbreed. What percentage of the progeny would have black coats ?

A

`25 %`

B

`50 %`

C

`75 %`

D

`100 %`

Text Solution

Verified by Experts

The correct Answer is:
C
The cross between black mouse (BB) and a brown mouse (bb) and the inbreeding of their hybrid progeny is shown below

Hence, phenotypic raio is 3 black : 1 brown i.e, 75 % of the progeny would have black coat.
