Eye color is also determined by genes. Brown eyes are dominant, and blue eyes are recessive. What must be true for two brown-eye
Troyanec [42]

Answer:

The brown-eyed parents must be HETEROZYGOUS to produce a blue-eyed child

Explanation:

This question involves a single gene coding for eye color in humans. The allele for brown eyes (B) are dominant over the allele for blue eyes (b). This means that an individual that is heterozygous (Bb) will phenotypically have a brown eyes.

According to this question, a blue-eyed child (bb) will be produced when two brown-eyed parents are HETEROZYGOUS (Bb) for the eye color trait. This means that each of the parent donated the recessive allele (b) to produce the (bb) offspring. Please find the punnet square attached.

The information that determines what an organism will be like is stored in the _____________ molecule.
Alchen [17]
<span>The information that determines what the organism will be like is the DNA molecule. It is made up of nucleotides. These nucleotides are linked chains. The four types of bases found in nucleotides are: adenine, thymine, guanine, cytosine. The order of the bases determines what instructions are contained on the strand. For example, say a strand shows ATCTT and say that presents in a person who has blue eyes while other eye colors would be a different code. Wach piece of code determines what the organism will be like based on those pairs.</span>
