Brut [27]

Answer: In this type of cross between MmDdPp and mmddpp, the phenotypic ratios in the eight possible phenotypes are as follow; a. solid, normal, smooth = 1:8

b. solid, normal, peach = 1:8

c. solid, dwarf, smooth = 1:8

d. solid, dwarf, peach = 1:8

e. mottled, normal, smooth = 1:8

f. mottled, normal, peach = 1:8

g. mottled, dwarf, smooth = 1:8

h. mottled, dwarf, peach = 1:8

Explanation: The number of gametes that can be formed from a particular genotype is given as 2^n where n is the number of heterozygous loci. In the genotype MmDdPp, n = 3. Therefore, 8 gametes can be formed.

In genotype mmddpp, n = 0. Therefore, only one type of gamete can be formed.

Crossing the two genotype (MmDdPp and mmddpp) as shown in the attached image, 8 possible offsprings can be achieved. Phenotypes of these offspring had been stated earlier. The phenotypic frequency of each of these offspring is one out of eight (⅛).
