X-linked lissencephaly is an X-link dominant trait pertaining to a brain disorder. It superficially resembles an autosomal dominant trait because both the daughters and sons of an affected female parent can be affected. Mr. Panganiban is affected by the said disorder while his wife is not. Using your knowledge in predicting the genetic possibilities of the offspring, what do you think would happen to their sons and daughters in the first filial generation? Females affected by an X-link dominant have 50% for their sons and daughters to be affected. Father affected by the X-linked dominant trait can transmit the trait to all his daughters. Males with lissencephaly could transmit the genetic disorder for both sons and daughters. Lissencephaly is an X-link limited dominant trait. It usually affects males because they have only a single chromosome.

Hemophilia is another example of a X-linked disease caused when a recessive allele (Xh) is expressed. If a normal male reproduces with a heterozygous normal female, what are the expected genotypes and phenotypes? Will any of their daughters develop hemophilia? As in the previous question, you must also give the gender of the child in your genotype and phenotype descriptions here.

A type of red-green colorblindness is inherited recessively on the X chromosome. A woman who is a carrier had children with a male that is not affected by the disease. Show your answers with the use of a Punnett square • What is the probability (% or likelihood) that a child is affected by the disease? • What is the probability (% or likelihood) that a son is a carrier? (Careful!) • Is there a chance that a girl of the couple is affected by the disease?

Duchenne muscular dystrophy is an X-linked, recessive disorder in which muscles waste away early in life, resulting in death in the teens or twenties. A man and woman in their late thirties have five children—three boys (ages 1, 3, and 10 years) and two girls (ages 5 and 7 years). The oldest, boy shows symptoms of the disease. What are the probabilities that their other children will develop the disease? Give only typing answer with explanation and conclusion
Suppose gene B is X-linked and is embryonically lethal when homozygous or hemizygous recessive. A man marries a woman who is heterozygous for this gene. They want to have three kids – one girl and two boys. Using a Punnett square, answer the following: What is the probability that they will have a son that dies before birth? _______________________ What is the probability that they will have a daughter who has the same genotype as her mother? _________________ One of their daughters eventually has a child with a man. One of their sons dies before birth. What was the genotype of this daughter? _______________________________ please show me how to get the answer and explain how you got and use a punnet square
A man with X-linked color blindness marries a woman with no history of color blindness in her family. The daughter of this couple marries a normal man, and their daughter also marries a normal man. What is the chance that this last couple will have a child with color blindness? If this couple has already had a child with color blindness, what is the chance that their next child will be color blind?
X-linked ichthyosis is an X-linked recessive trait that manifests in part as dry, scaly skin (“ichthy-” = fish or fish like). Suppose a couple are considering having a child together. Parent A is heterozygous for the ichthyosis allele while Parent B is hemizygous negative for the ichthyosis allele. What is the probability their child would be unafflicted with ichthyosis but be a carrier of the ichthyosis-causing allele? a.0% b.25% c.50% d.75% e.100%
Y-linked Amelogenesis imperfecta (A), a congenital disorder that affects the formation of the teeth enamel making affected individuals at higher risk for dental cavities and related problems. X-linked dominant hypophosphatemia (H), a form of rickets or vitamin D deficiency that affects the bones which causes pain, osteoarthritis, and abnormal shapeabnormal shape. X-linked recessive progressive Duchenne muscular dystrophy (m), a muscular disorder, leading to an irreversible gradual wasting of skeletal muscles. Hannah, the same as her mom, is heterozygous for both X-linked traits. While her dad is suffering from both muscular dystrophy and hypophosphatemia. Hannah's husband, Joey has a mom suffering from musculardystrophy regardless of having normal bone conditions.

By looking at the following pedigree can you conclude why is it an X-linked recessive? If yes, why not dominant, Sex influenced, or Autosomal. Please provide sufficient reasoning, Thank you.
Duchenne muscular dystrophy (DMD), marked by muscular degeneration, results from an X- linked recessive gene. Thus, a female who is heterozygous for this gene and does not have the disease can be a carrier. What kind of offspring can you expect from a DMD-affected male and a carrier female? Can there be a carrier male?
