How are the alleles for sex-linked traits inherited? They are passed from the Y chromosome in parents to the X chromosome in offspring. They are passed from the X chromosome in parents to the XY chromosome in offspring. They are passed from parents to offspring on the X and Y chromosomes. They are passed from any chromosome in the parents to the X or Y chromosome in the offspring.

Answers

Alleles for sex-linked traits are inherited in such a way that they are passed from parents to offspring on the X and Y chromosomes.

Generally, sex-linked traits are traits or genes that are found on the sex chromosomes only. In humans, females have XX sex chromosomes while males have XY sex chromosomes.

  • Thus, X-linked traits are passed from parents to offspring via the X chromosomes only. Since both males and females have X chromosomes, it means both genders can have X-linked traits.

  • Y-linked traits are passed from parents to offspring via the Y chromosomes only. Since only males have Y-chromosomes, it means that only the male gender can have Y-linked traits.
