Question

place the labels in the appropriate blanks to describe the outcome of a cross between flower color alleles that exhibit incomplete dominance. labels may be used more than once.

Answer 1

In incomplete dominance, neither of the alleles completely dominates over the other one. Coss: RW x RW. F1) 25% RR homozygous red, 50% RW heterozygous pink, 25% WW homozygous white.  

What is incomplete dominance?

Incomplete dominance is one of the different types of inheritance patterns.

In these cases, neither of the involved alleles completely dominates over the other one. This is, the dominant allele can not mask the expression of the recessive allele in heterozygous individuals.

The resulting phenotype when different alleles are combined in the same genotype is an intermediate expression between the two extremes phenotypes.

Heterozygous individuals are different from both the dominant and recessive homozygous parents and express a mixture of both homozygous progenitors.

I will consider the following cross. I advise you check if this is the same as yours.

Alleles

• R is the allele that codes for red
• W is the allele that codes for white

Genotypes    Phenotypes

RR                        RED flower

RW                       PINK flower

WW                      WHITE flower

Cross: between two plants with pink flowers

Parentals)   RW  x  RW

Gametes) R    W   R   W

Punnett square)    R            W

                      R      RR          RW

                      W     RW         WW

F1)

• 25% = 1/4 of the progeny is expected to be homozygous RR and express red flowers

• 50% = 1/2 of the progeny is expected to be heterozygous Rr and express pink flowers

• 25% = 1/4 of the progeny is expected to be homozygous WW and express white flowers
