A researcher studied six independently assorting genes in a plant. Each gene has a dominant and a recessive allele: R black stem, r red stem; D tall plant, d dwarf plant; C full pods, c constricted pods; O round fruit, o oval fruit; H hairless leaves, h hairy leaves; W purple flower, w white flower. From the cross (P1) Rr Dd cc Oo Hh Ww x (P2) Rr dd Cc oo Hh ww. Required:
a. How many kinds of gametes can be formed by P1?
b. How many genotypes are possible among the progeny of this cross?
c. How many phenotypes are possible among the progeny?
d. What is the probability of obtaining the Rr Dd cc Oo bb ww genotype in the progeny?
e. What is the probability of obtaining a black, dwarf, constricted, oval, hairy, purple phenotype in the progeny?
