1- In guinea pigs, the gene b producing white fur is recessive to the gene B that produces black fur. A heterozygous black guinea pig is crossed to a white. a. Diagram this cross b. What will be the genotypic ratio? c. What will be the phenotypic ratio?
12. In garden peas, the dominant gene R produces round seed coats while the recessive gene r produces wrinkled seed coats. A homozygous round is crossed to a wrinkled.
a. Diagram this cross showing all genotypes and gametes. b. What will the phenotypes of the offspring be?
b. Two of these round offspring are crossed together to produce the next generation.
c. Diagram this cross
d. What will be the phenotypic ratio?
e. What will be the genotypic ratio?
f. If 444 seeds are produced in this cross, how many should produce plants bearing round seeds?
