Question

Which is/are possible genotypes for a person with straight little finger and brown eyes?

a. bbrr
b. bbRR
c. BbRr
d. bbRr

Answer 1

The correct answer is b. bbRR.

Step-by-step explanation:

• Brown eyes color is dominant over blue eyes color. So, we can assign the letter R to the dominant allele that expresses brown eyes and r to the recessive allele that expresses the blue eyes.

• The phenotype bent little finger is dominant over the phenotype straight little finger. We can assign the letter B to the dominant allele, and b to the recessive allele.

a. bbrr : This genotype belongs to a person with blue eyes and straight little finger

b. bbRR : This genotype belongs to a person with brown eyes and straight little finger

c. BbRr : This genotype belongs to a person with brown eyes and bent little finger

d. bbRr: This genotype belongs to a person with brown eyes and straight little finger.
