most human cells possess pairs of chromosomes. on average, a human chromosome contains different genes. if a human has two variants of a gene at the same locus, the person is for that gene. if the two alleles are identical at the same locus, the person is for that gene.
23 10 heterozygous loci over a thousand homozygous

Explanation:

• Human cells typically have 23 pairs of chromosomes.
• A human chromosome contains over a thousand genes.
• When there are two variants of a gene at the same locus, the person is heterozygous.
• When two alleles are identical at the same locus, the person is homozygous.

Answer:

Most human cells possess 23 pairs of chromosomes. On average, a human chromosome contains over a thousand different genes. If a human has two variants of a gene at the same locus, the person is heterozygous for that gene. If the two alleles are identical at the same locus, the person is homozygous for that gene.
