Answer 1

To illustrate a heterozygous gene pair, let's say we have a pair of chromosomes that each represent a specific gene. In this example, we will focus on a gene represented by the letter "A".

1. Chromosome from Parent 1:

   • Gene location: A (dominant allele)

2. Chromosome from Parent 2:

   • Gene location: a (recessive allele)

Since the two alleles are different (A from one parent and a from the other), this person is considered heterozygous for that particular gene.

Visualization:

If you were to visualize this, you could draw two chromosomes side by side:

Chromosome 1:  |--- A ---|
Chromosome 2:  |--- a ---|

You would then circle the "A" on Chromosome 1 and "a" on Chromosome 2 to indicate that this gene is heterozygous.

Since I can't provide drawings within this format, you could create a simple diagram based on the above description. If you were to circle "A" and "a", it would clearly represent that the individual has one dominant and one recessive allele for that gene.
