There are two different alleles for flower color, P and p. The image shows a white sweet pea that is labeled with its two alleles for petal color.

A white sweet pea is labeled p p.

What can you surmise from the labeled image?
A.The genotype is heterozygous.
B.White petal color is a recessive trait.
C.White petal color is a dominant trait.
D.The phenotype is heterozygous.

B. White petal colour is a recessive trait.

Step-by-step explanation:

In Mendelian genetics, the alleles depicted in small letters are recessive traits.

Since both alleles are same and in lower case they are homozygous recessive alleles for a white coloured petal gene.

The genotype of the trait will be tt because if it is crossed either with heterozygous or homozygous P alleles it will appear as tt to have phenotypic trait of white colour.

So the genotype will be tt.
