a.
To determine:
The result of the first filial generation, in which all the offspring are black when the white guinea pig having ovary of black guinea pig is mated with white guinea pig.
Introduction:
The black color coat is dominant over the white color coat in guinea pigs. The presence of two copies of recessive alleles leads to the expression of white coat, while the presence of one or two dominant alleles leads to the expression of black coat.
b.
To determine:
The genotypes of all the offspring in this cross.
Introduction:
The black color coat is dominant over the white color coat in guinea pigs. The presence of two copies of recessive alleles leads to the expression of white coat, while the presence of one or two dominant alleles leads to the expression of black coat.
c.
To indicate:
The validity of pangenesis and the germ-plasm theories.
Introduction:
The black color coat is dominant over the white color coat in guinea pigs. The presence of two copies of recessive alleles leads to the expression of white coat, while the presence of one or two dominant alleles leads to the expression of black coat.
