In tigers, a recessive allele causes a white tiger (absence of fur pigmentation). If one phenotypically normal tiger that is heterozygous is mated to another that is phenotypically white, what percentage of their offspring is expected to be white?

Respuesta :

Answer:

50% are white (ww)

Explanation:

As given, white color is a recessive phenotype, so white tiger will contain both the alleles in recessive condition, means it must be homozygous recessive.

Let ww as white tiger

so, white tiger= ww

And heterozygous tiger will be =Ww ( normal tiger)

cross between white  and normal tiger:

Parents:    Ww × ww

offspring: Ww, Ww, ww, ww

50% are white (ww);

while 50% are normal (Ww).
