Answer :
a. The blood types that are possible for the father of Barry's child are:Type OType ABType BType Ab. If Chaplin had possessed one of these blood types, it would not necessarily prove that he fathered Barry's child because Type B is a genotype that is a result of two different genotypes.
So, it could be the combination of either IA IB or IB IB. Hence, there could be a probability of Chaplin being the father of Barry's child. (Note: Blood type is not a definitive test of paternity. Blood tests can help determine paternity, but other factors must also be taken into account such as family history, medical tests, and DNA testing.)b.

3.In goats, the dominant beard allele B' is present only in males, while the recessive allele b' is present only in females. Here, the bearded phenotype in goats is autosomal, while coat color (black or white) is another autosomal trait that is dominant and follows the principle of independent assortment.a. The cross between a male with genotype B'B" Ww and a female with genotype B' B' Ww will produce the following genotypes: {B'B'Ww, B"B'Ww, B'B'ww, B"B'ww}. The phenotypes expected for the crosses are 50% bearded and black, 50% bearded and white.b. The cross between a male with genotype B'B' Ww and a female with genotype B' B' ww will produce the following genotypes: {B'B'Ww, B'B'ww}.
