- A person who is a carrier for a genetic trait ___________. a. is heterozygous for a dominant trait b. is heterozygous for a recessive trait c. is homozygous for a recessive trait d. could be either a or b but not cIn 1-3 sentences define the following heredity types: Autosomal dominant and recessive, X-linked dominant and recessive, epistasis, polygenic, codominantA man is a homozygous for a disease. He marries a woman who is heterozygous for the disease. A son and a daughter were born to them. The daughter has the disease but the son is only a carrier. Their daughter then marries a man who is normal for the disease. Two daughters who both have the disease were born to them. What are their genotypes of all of them? What is the type of inheritance observed?
- The gene for eye color has several alleles. The allele for brown eyes is symbolized with B and the allele for blue eyes is symbolized with b. A father has the phenotype of blue eyes (recessive trait) and a mother has a phenotype of brown eyes (dominant trait.). If they have a child, what is the most likely genotype? Bb bb BB none of theseGrandma Jade is affected with tuberous sclerosis, she grows benign tumors, and the trait is under control with her doctors. She is married to Grandpa Phil, who does not have the trait. Out of their four children, only one, Michael, has tuberous sclerosis. Complete the Punnett Square and indicate their genotypes.Hemophilia is an X-linked disorder that affects the body’s ability to create blood clots. The allele for normal blood clotting, XH, is dominant over the allele for hemophilia, Xh.An unaffected female that is not a carrier mated with an affected male. Which of the following rows identifies the possible genotypes of the offspring?
- A man is a homozygous for a disease. He marries a woman who is heterozygous for the disease. A son and a daughter were born to them. The daughter has the disease but the son is only a carrier. Their daughter then marries a man who is normal for the disease. Two daughters who both have the disease were born to them. What are the genotypes of all of them?Complete a new Punnett Square below, for a woman who is a carrier for sickle cell, who is married to a man who has normal hemoglobin and is homozygous. A carrier for a recessive trait has a heterozygous genotype that "carries" the recessive allele without expressing it, since the dominant allele is expressed. Women or men can be carriers of traits on non-sex chromosomes, or autosomes. What are the possible genotypes that you can identify, do any of the possible genotypes result in sickle cell anemia, and what is the chance that any of the offspring are carriers for sickle cell anemia?A man is homozygous dominant for fair skin and heterozygous for black-straight hair, his wife has brown skin and black-curly hair. The wife's hair color is the same genotypically with the husband. His mother in-law hair color is red since birth. The couple wanted to have kids. Give the genotype of the husband
- A couple each with blood type AB and normal pigmentation have a child with AB blood type and albinism. What is the probability that their next child will have the same phenotype as the first child? Assume that albinism is recessive to normal pigmentations and that this trait assorts independently from the blood group genotypes. Group of answer choices 3/16 9/16 1/8 1/4 1/16Assume for a moment that a child has a autosomal recessive disorder, but both parents appear normal. What is the genotype of both parents? : one parent must be homozygous dominant : both parents must be homozygous recessive : both parents are heterozygous : both parents nust be homozygous dominantColor-blindness is an X-linked recessive disorder. Under what circumstances will this condition manifest in a child? Top of Form If the child is a male and its mother has the recessive allele If the child is a female and its father has the recessive allele If the child is a female and its mother has the recessive allele If the child is a male and its father has the recessive allele
