How many different types of phenotypes are possible when working various pea seed-color problems?
a. 3
b. 4
c. 5
d. 6
e. 2

e. 2

Explanation:

The seed color in a pea plant is a discontinuous trait and is regulated by two alleles of a gene. The dominant allele imparts "yellow" color to the seeds while the recessive allele imparts them "green" color.  

If the dominant allele is represented by letter "Y" and the recessive allele is written as the lower case letter "y"; the homozygous dominant and heterozygous dominant genotypes exhibit "yellow" phenotype with respect to seed color while the homozygous recessive genotype express "green" seed color.
