2. Actress Joan Barry's paternity suit against actor Charlie Chaplin was based on blood types. Joan was Type A, Charlie was Type O, and the baby was Type B. Could Chaplin have been the father of her child?

a. What blood types are possible for the father of Barry's child?

b. If Chaplin had possessed one of these blood types, would that prove that he fathered Barry's child?

3. In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We'll use the symbol B' for the beard allele and B" for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their proportions expected for the following crosses:

a. B'B" Ww male × B'B' Ww female

b. B'B' Ww male × B'B' ww female

c. B'B' Ww male × B'B' Ww female

d. B'B' Ww male × B'B' ww female

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. If Chaplin had possessed one of these blood types, it would not necessarily prove that he fathered Barry's child because 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.

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}.
