Q) 30

In some animals, B is the allele for normal skin (without spots) and b is the allele for spotted skin.
A pair of these animals has 37 offspring, 18 with spots and 19 without.

What are the most likely genotypes of the parents?
A) BB × BB B) Bb × Bb C) Bb × bb D) bb × bb

Answer is C, someone please explain this to me very carefully? I hate these type of Qs

 

[JOEJOE]

That means half r spotted and half r not spotted(normal)... So the genotype of the offspring is Bb and bb so how can we achieve that... look for the 2 parent genotypes that give the offsprings Bb and bb .. so

If u cross Bb and bb u will get 2 Bb and 2 bb therefore answer is C... i know this is very complicated but these questions come all the time u have to understand them welll and revise genetics

Got it! Cheers, but erm... you say half are spotted and half are not - even though it is 18 and 19? Or does that not matter?
