Question

a. a segment if DNA that codes for brown eye color
b. a section of DNA that determines eye color
c. a sex chromosome that determines whether you are male or female
d. a DNA sequence that produces a protein

Answer 1

The correct answer will be option-B

Step-by-step explanation:

An allele is the variable form of a gene which determines the characteristic or trait of an organism.

The gene exists in many or multiple forms in an organism where each form is known as the allele. These forms usually occur on the same locus or position of the chromosome on chromosomes in pairs.

During fertilization, allele controlling a single trait of an organism from male and female gamete fuse and shows its effect by producing a phenotype of the organism.

Thus, Option-B is the correct answer.
