How are sex-linked traits inherited? alleles are passed from the parents’ sex chromosomes to nonsex chromosomes in the offspring. alleles are passed from the parents’ nonsex chromosomes to the sex chromosomes in the offspring. alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring. alleles are passed from the parents’ nonsex chromosomes to nonsex chromosomes in the offspring.

The right answer is Alleles are passed from the parents’ sex chromosomes to the sex chromosomes in the offspring.

In the case of a so-called X-linked recessive disease, the gene responsible for the disease is on the X chromosome. One of the important consequences of a gene on a sex chromosome is that the disease caused mutation of the gene (definitive transformation of a gene) will affect boys and girls differently. This difference is due to the fact that boys still have only one X chromosome in each cell, which is transmitted to them by their mother, while girls receive an X chromosome from each of their parents and each of their cells involves so two X chromosomes.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
