Question

inquizitive chapter 8: chromosomes and human genetics: curing the incurable 8.2. diagram a chromosome, identifying genes, alleles, and loci. complete the following passage regarding the structure of a chromosome. 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. over a thousand 10 heterozygous homozygous loci 23

Explanation:

Step1: Recall human chromosome number

Most human cells have 23 pairs of chromosomes.

Step2: Recall gene - number in human chromosome

On average, a human chromosome contains over a thousand different genes.

Step3: Recall genetic - term for different alleles

If a human has two variants of a gene at the same locus, the person is heterozygous for that gene.

Step4: Recall genetic - term for identical alleles

If the two alleles are identical at the same locus, the person is homozygous for that gene.

Answer:

23; over a thousand; heterozygous; homozygous
