Answer:
The mentioned characteristics of variability are witnessed because of the phenomenon known as X chromosome inactivation in heterozygous females. As females possess two X chromosomes, they actually should not possess any color blindness.
The phenomenon of X-chromosome inactivation takes place in a random manner at the time of embryo development. During this only one X chromosome is inactivated. If the chromosome comprising the defective gene is inactivated, the individual will possess normal vision.
If the chromosome comprising the usual gene gets inactivated than the individual will be color blind. In the given case of female, X inactivation took place in one eye. The inactivation of normal alleles has taken place and thus she possesses normal vision with one eye and is color blind in the other eye.

Answer:
Baby 1 is the Smith's and baby 2 is the White's
Explanation:
Looking at the table and finding both of the parents blood types, seeing where they intersect at a square you can find what the baby's possible blood types are. Looking at the Smith's, going from both the B blood types you can see that the possible blood types are B or O. The White's blood types are AB and B, looking at the chart you can find the baby's possible blood types are A, B or AB but not O, so baby 1 cannot be their child.
