Summary Introduction
Introduction: Chromosomes are the large molecules of genes or DNA. The necessary information for every character of an organism is contained in the DNA. Sex chromosomes are those chromosomes that play a crucial role in determination of Sex of the individual. Females have two X linked allele while the males have only one X linked allele as they contain one X chromosome in their genome.

Colorblindness is inherited as an X-linked recessive trait while pattern baldness is controlled by an autosomal
gene that is dominant in males but recessive in females. A colorblind man who is also homozygous for baldness
has children with a woman who carries normal genes for both traits. What is the probability that any of their child
will be:
a. Colorblind, bald male
b. Colorblind, normal-haired male
c. Female with normal sight and bald
Color blindness in humans is controlled by an X-linked completely recessive allele (Xc), while breast cancer is controlled by an autosomal completely dominant allele, B. A color blind male, who is a heterozygote carrier for breast cancer has three children/n with a normal eyed female (whose mother was color blind), who is homozygote recessive for the breast cancer allele. What is the probability that out of three children, 2 will be color blind males, and not show breast cancer, and one will be a color blind female, who shows breast cancer?
Choose correct option and do explain.
Considering an X-linked dominant trait, if an affected woman and an unaffected man decide to have children, which of the answer choices is possible for their children?
a.
All of their sons are expected to show the dominant trait.
b.
Their daughters are expected be heterozygous for the gene.
c.
Their daughters are not expected to show the dominant trait.
d.
Their sons are expected to be heterozygous for the gene.
e.
All their children, whether male or female, are expected to show the dominant trait.

- - Color blindness in humans is one example of a recessive X-linked trait. In a family in which there are two children, a son and a daughter, the daughter is color-blind but the son has normal vision. Which of the following could you most likely conclude about the mother and / or father of this family? a. The father has normal vision b. The mother has normal vision C. Both the mother and the father are color blind. d. Neither parent is color-blind.arrow_forwarda. Determine if the pedigree below can be for a trait that is X-linked traits. Write the genotype of each individual next to the symbol. b. Is it possible that this pedigree is for an X-linked recessive trait? c. What can you conclude about the children if both parents are affected with an X-linked recessive trait?arrow_forwardIchthyosis is a rare X-linked recessive disorder that is characterized by scaling of the skin around the neck and lower extremities. A young couple, Bart and Jenny, are expecting a child and are aware there might be a chance that their child could be affected by this disorder. Jenny (the wife) has ichthyosis, but Bart (her husband) is unaffected and completely normal with respect to the allele responsible for this disorder. A. Both Bart and Jenny were Biology majors as undergraduates. Knowing a little about the pattern of X-linked recessive inheritance, Bart and Jenny were concerned when ultrasound revealed that they would be having a son. However, genetic testing performed on the baby shortly after birth revealed that their newborn son, Mark, did not have ichthyosis. Explain how this could be the case, assuming that the gene responsible for ichthyosis is fully penetrant. If non-disjunction occurred, assume it happened in only one of the two parents, and during only one of the two…arrow_forward
