- 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 cA couple who wishes to have children visits you, a genetic counselor. There is a history of a deleterious recessive trait in males in the womans family but not in the mans family. The couple is convinced that because his family shows no history of this genetic disease, they are not at risk of having affected children. What steps would you take to assess this situation and educate the couple?Analysis of X-Linked Dominant and Recessive Traits The following is a pedigree for a common genetic trait. Analyze the pedigree to determine whether the trait is inherited as: a. autosomal dominant b. autosomal recessive c. X-linked dominant d. X-linked recessive e. Y-linked
- If an individual does not have a widow's peak, which genotypes are possible for their offspring? Homozygous recessive Homozygous dominant Unable to determine HeterozygousIf an individual has a widow's peak, which genotypes are possible? Homozygous recessive Unable to determine Homozygous dominant HeterozygousNicki Minaj and Meek Mill broke up because Nicki Minaj thinks if they were to have kids they would not have dimples like she does. If dimples are dominant over no dimples, use the Punnett square to figure out the probability their child would have dimples. Nicki Minaj is homozygous DD and Meek Mill is heterozygous Dd
- If an individual has a widow's peak, but one of their parents does not, which genotypes are possible? Heterozygous Homozygous dominant Homozygous recessive Unable to determinePeople with recessive disorders are usually born to normal parents who are both heterozygotes which means that both parents are carriers of the dominant allele for the disorder but appear normal themselves. Select one: True FalseA woman with Huntington’s disease (autosomal dominant trait, and she is heterozygous) has children with a healthy man. What proportion of their children will inherit Huntington’s disease?
- Male-pattern baldness is sex-linked and recessive. A carrier female has a child with a normal male.

What would be the phenotype of a person who is heterozygous for this trait?Assume 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 dominant
