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.
