_______ is when the phenotype of the offspring does not reflect its genotype but rather that of the mother.     Maternal effect     Paternal effect     Sex-influenced     X-linked

A color blind (X linked recessive) female marries a normal male. What percent of her daughters will be color blind.

Number of FEMALE offspring that would have the condition of an X-linked trait, if an affected man and a carrier woman had children

Which one of the following phenotypes is passed from mother to all her male and female children? O Y-linked Mitochondrial X-linked dominant Autosomal dominant

A male presenting with clinical features as greater height, poor coordination, less body hair, breast growth and seems less interest in sex. He is also facing difficulty in speech. What your knowledge depicts that he is suffering from which genetic disease.

Hemophilia, disease in which the blood lacks a clotting factor, is caused by an X linked recessive gene. Joe doe not have hemophilia and Lucille is heterozygous for the condition.  What is the chance that their MALE child will have hemophilia? (Note: you are calculating the probability for their MALE children only, in other words if they have 1 male child, what is the probability that he will be born with the disease?)     0%     1/4 or 25%     2/4 or 50%     3/4 or 75%     4/4 or 100%

The allele for color blindness is carried on the X chromosome. Making color blindness a recessive trait an X-linked trait. A colorblind male and a carrier female for color blindness. Have a child. What is the percent chance that their son will be color blind? (I don’t want the answer to be wordy so please no internet answers just helpful clear answers)

Duchenne’s muscular dystrophy (DMD) is an X-linked disease that causes progressive muscle weakness and is often fatal. “XD” represents the wild type allele, and “Xd,” the mutant allele. Jonah is XDXd Y and his brother Pete is Xd Y. Jonah and Pete BOTH have DMD of equal severity and phenotypes. You might have thought Jonah’s DMD would be less severe given his genotype. To better understand the situation, you investigate Jonah’s Xist chromosome region in his defective muscle cells. Which of the following is consistent with his phenotype? (Select all that apply.) The Xd-containing chromosome is inactive in defective muscle cells. The XD-containing chromosome has a methylated Xist promoter. The XD-containing chromosome has an unmethylated Xist promoter. The Xd-containing chromosome is active in defective muscle cells.

Down syndrome is an example of which type of genetic disorder?​ Autosomal-dominant disorder X-linked recessive disorder Multifactorial disorder Chromosomal disorder
