1. A/n _ is a family tree used to study inheritance of a trait in humans.
2 Huntington's disease is an example of a/n disorder, where anyone with one
copy of the allele that causes Huntington's will exhibit the disorder, and the allele is
not located on a sex chromosome.
3. Red-green color blindness is an example of a recessive disorder, passed on
the X chromosome,
4 Females can be carriers for recessive alleles located on the . but males
cannot

Respuesta :

Answer:

1. pedigree

2. autosomal dominant

3. sex-linked

4. x chromosome

5. profile of a person's chromosomes. Karyotypes reveal many important characteristics about a person's chromosomes, such as how many chromosomes they have, and the relative size, shape, and appearance of the chromosomes.

6. Females have the sex chromosomes XX, and males have the sex chromosomes XY. Each child obtains one sex chromosome from his or her biological mother and one sex chromosome from his or her biological father. Males receive a Y chromosome from their fathers and an X chromosome from their mothers. X-chromosome linked disorders, then, can be passed on to males from their mothers but never from their fathers.

7. a) autosomal dominant alleles lead the expression in the child. b) autosomal recessive alleles are only expressed if the other allele is homozygous. c) sex-linked dominant and d) sex-linked recessive are not applicable to sex-linkage only due to the fact that females can be hetero or homozygous.

  • A Pedigree is a family tree used to study the inheritance of a trait in humans.
  • Huntington's disease is an example of an autosomal dominant disorder, where anyone with one copy of the allele that causes Huntington's will exhibit the disorder, and the allele is not located on a sex chromosome.
  • Red-green color blindness is an example of a sex-linked recessive disorder, passed on the X chromosome.
  • Females can be carriers for recessive alleles located on the X-chromosomes but males can not.

What is Pedigree analysis?

Pedigree analysis may be defined as the study of the inheritance of genetic traits in several generations of a human family in the form of a family tree diagram.
