2. In guinea pigs, black coat color (W) is dominant to white coat color (w). Castle and Phillips (1909) transplanted an ovary from a black guinea pig into a white female whose ovaries had been removed. They then mated this white female with a white male. All the offspring from the mating were black in color.

a. Explain the results of this cross.

b. What is the genotype of the offspring from this cross?

c. What, if anything, does this experiment indicate about the validity of the pangenesis and germ-plasm theories?

2. Based upon the information above, which genotype below wouldbest reflect a whack winged male?

A. w // + B. + // + C. w // w D. w/ Y E. +/ Y 15.

1. a). The position of the flower on the stem of the garden pea is governed by a pair of alleles. Flowers growing in the axis (upper angle between petiole and stem) are produces by the action of a dominant allele 'T', those growing only at the tip of the stem by its recessive allele 't'. Colored flowers are produced by a dominant gene 'C', and white flowers by its recessive allele 'c'. A dihybrid plant with colored flowers in the leaf axis is crossed to a pure strain of the same phenotype. What genotypic and phenotypic ratios are expected in the F1 progeny?

b). In summer squash, white fruit color is governed by a dominant allele (W) and yellow fruit color by the recessive (w). A dominant allele at another locus (S) produces disc-shaped fruit and its recessive allele (s) yields sphere-shaped fruit. If a homozygous white disc variety of genotype 'WWSS' is crossed with a homozygous yellow sphere variety (wwss), the F1 are all white disc dihybrids of genotype 'WwSs'. If the F1 is allowed to mate at random, what would be the phenotypic ratio expected in the F2 generation?

Hi, Can you please explain clearly. Thank you.
