Select all of the statements below that are true. Group of answer choices If you inherit a dominant allele for a particular gene from your mother and a recessive allele for the same gene from your father, the recessive allele from your father will not contribute to your phenotype but it may be passed on to your children and contribute to their phenotypes. It is theoretically possible for a woman to have hemophilia A. (Note that hemophilia A is an X-linked recessive trait Daughters receive a Y chromosome from thier fathers. Sons recieve an X chromosome from thier mother.

Step 1
- Statement 1: True. If you have one dominant allele (from mother) and one recessive allele (from father) for the same gene, the phenotype is dictated by the dominant allele, but the recessive allele can be passed to offspring and may affect their phenotypes if Show more…

In humans, hemophilia A is inherited as an X-linked recessive trait. If a man and a woman produce a daughter who is afflicted with this disorder, which of the following must be true? Assume that one parent is afflicted and one is healthy. Select all that apply. _____________________ The mother is a carrier of hemophilia. The father is also afflicted with hemophilia. The daughter inherited a recessive gene from each parent. If the girl has children, 100% of her daughters will also be afflicted. The mother must be heterozygous. The daughter inherited a dominant allele from her mother.

Couple has two offspring; one child with an autosomal recessive disease trait and one normal. What conclusions can we make about the parents? One parent must have the autosomal recessive disease. Both parents must carry the autosomal recessive disease. One parent is a carrier for the autosomal recessive disease and the other parent is normal. Both parents probably carry the autosomal recessive disease. Which of the following is generally true of an X-linked recessive pedigree? Disease affects more males than females. Pattern of skipped generations. Males are usually affected. Mothers can transmit the disease to their daughters. Which of the following genetic diseases is transmitted through autosomal recessive inheritance? Duchenne muscular dystrophy. Cystic fibrosis. Hemophilia. Huntington's disease. Diabetes mellitus type 2 can be common within a family, and yet no single gene has been identified causing the problem, although diet and exercise habits influence whether the disease develops. This disease is probably controlled by: complex gene regulation. autosomal recessive mutation. multifactorial inheritance. A 41-year-old pregnant female miscarries her first fetus. Analysis shows that the fetus had 45 chromosomes. Which of the following describes this condition? Euploidy. Triploidy. Tetraploidy. Aneuploidy. Genetic testing reveals that a woman has inherited a autosomal dominant disease gene from her mother, and yet she does not exhibit any symptoms of the disease. Which of the following could best explain this? The disease has incomplete penetrance. The disease is caused by epigenetic modifications. She is a chromosomal mosaic. She has Turner Syndrome. A healthy couple has a child with hemophilia. The couple later divorces and each remarries. Which of the following statements is correct? If the father has more children with his new wife, there is a 50% chance that his daughters will have hemophilia. If the father has more children with his new wife, there is a 50% chance that his sons will have hemophilia. If the mother has more children with her new husband, there is a 50% chance that her sons will have hemophilia. If the mother has more children with her new husband, there is a 50% chance that her daughters will have hemophilia.

Text: Select all the correct answers from the list below about X and Y chromosome inheritance patterns: X-linked genes are heterozygous in females and homozygous in males. It is impossible for a female to have an X-linked disorder (like hemophilia). A female can pass X-linked genes only to her sons. A male can only pass X-linked genes to his daughters. Correct. If a man has a disorder caused by a dominant X-linked allele, all his daughters will be affected.
