Question

In pea plants, flower color is controlled by a pair of alleles where purple (P) is dominant to white (p).

a. True
b. False

Answer 1

True

Step-by-step explanation:

An allele refer to two alternative forms of the same gene. An allele is a pair of genes found on a given chromosome. Usually, every allelic pair has one which is dominant and one which is recessive.

The dominant allele is expressed while the recessive allele is not expressed.

The colour of the pea plant is controlled by a pair of alleles wherein purple (P) is dominant to white (p).

The expressed colour of the pea plant(phenotype) is dependent on the arrangement of the genes(genotype) of the pea plant.
