A white flower with a homozygous recessive genotype for petal color would have a
genotype of:
•
.
A. WW
B. rr
C. Rr
D. RR

B. rr

Explanation:

Genotype- Is the genetic makeup of an organism.

An homozygous individual is one who has similar allele e.g AA

It could either be in dominant form(AA) or recessive form(aa)

An heterozygote individual has two different allele in its genotype e.g Aa

A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.

The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.

The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.
