the answer is B.. There will form 3 different genotypes.. The BB is same as B while the bb is same as b so in the first filal generation,
B * b
Bb ( first filal generation)
So. Bb * Bb
BB Bb Bb bb ( second filal generatio)
So 3 genotypes ( BB, Bb and bb) are formed.. Gracias
the answer in correct
in genes,there is first filial and second filial generation.
to get the answer,you have to pair them ,that is the first and the second.
as you can see for the second,there is BB,BB and BB
those are the three genotypes
I Don't think the answer is there because if we carry out a cross test all the offspring have the same genotypes.
The selected answer for thus question is wrong the answer is supposed to be two but they chosed 3
It's just 1, Bb (4 of it), No answer there, anything picked results in negative marking
Der will b a brown mouse n a black mouse in the family and equally a brown-black mouse...its genetic...one will definetly get both colors
