Answer:
Option A
Explanation:
Given -
Man has X-linked recessive trait . Thus its genotype can be represented as
YX'
Woman has normal vision with homozygous genotype i.e "XX"
A cross is carried out between the above two parents thereby producing following offspring -
Y X’
X XY XX’
X XY XX’
Out of four offspring two are boy "XY" which do not have Red-Green Color blindness
