Question

A pea plant is heterozygous for flower color. The two possible flower colors are the dominant purple and the recessive white. What color is this
heterozygous flower?
O white
O a blend of purple and white
O purple
it is impossible to tell the flower color from this information

Answer 1

Answer:

In a pea plant heterozygous for the color of the flower, the color exhibited by that flower the phenotype is purple.

Explanation:

According to Mendelian heritage, a dominant trait will always be present in the phenotype, even in the allelic heterozygous form, while a recessive allele will only be possible when there are two identical recessive alleles.

The presence of a dominant allele inhibits the expression of a recessive allele.

If for the character "color of the flower" the pea plant is heterozygous, it will exhibit the dominant trait in its phenotype, so its flowers will be purple.

The other options are not correct because:

• White is the recessive trait in the flower color
• A mixture of purple and white can be observed in co-dominance or incomplete dominance, non-Mendelian forms of inheritance.
