Albinism in humans is inherited as a simple recessive trait. Determine the genotypes of the parents and their children when a normal male and albino female have 2 normal and 2 albino children.

Look at the pedigree below and answer the following questions related to the human genetic trait depicted in this pedigree.  1.  Indicate whether the pattern of inheritance associated with this human trait is most likely to be (i) rare X-linked recessive, (ii) sex-influenced, or (iii) sex-limited.  You may assume that the gene is fully penetrant. Then, provide a specific reason that justifies your selection of this pattern of inheritance as the correct one, and also explain why each of the other two alternatives are not correct.  As part of your answer, include the phenotypic ratio, including the sex of the offspring, that you would expect to find in each of the three possible scenarios.

Two autosomal mutations include albinism and dwarfism. Albinism (a) is recessive, and dwarfism (D) is dominant. Complete a dihybrid cross of two people that are heterozygous for normal pigmented skin. One person is normal height and has no genetic trace of dwarfism in the family. The other person has dwarfism but has a mother who is normal height. 21. Complete a full dihybrid Punnett square (6pts).

Amelogenesis imperfecta (AI) is a disorder of faulty tooth enamel formation. It is inherited in an autosomal dominant and X-linked dominant pattern. The expression of AI disorder is determined by mutations in the autosomal alleles. One copy of the mutated allele (A) will cause the disorder. The severity of the disorder is determined by mutations in a gene carried on the X chromosome. Normal (or non-severe) abnormality (XN) is dominant over the abnormality (or severe) (Xn) allele. In the absence of the autosomal dominant allele, the abnormality gene on the X chromosome is notexpressed. Question:A woman with normal teeth had four children with a man with non-severe form of AI: A boy was born without amelogenesis imperfecta A girl was born without amelogenesis imperfecta  A boy was born with severe amelogenesis imperfecta A boy was born with non severe amelogenesis imperfecta Identify the parental genotypes.  Complete the Punnett square for the parental cross, and identify the possible…

PLEASE ANSWER PART C.

The questions below all refer to the following pedigree. The locus for allele D/d determines how cilia function within the body. Mutations at this allele cause abnormal ciliary function, resulting in a clinical disorder characterized by frequent respiratory infections (including in the ears, sinuses, and lungs), as well as infertility. In the pedigree, black circles/squares represent individuals affected by the disorder. White circles/squares represent unaffected individuals. Remember, if a trait is rare in a population (such as this one), we assume individuals marrying into the family are NOT carriers unless the information provided indicates otherwise. A1 A2. || B1. B2.

There are six types of agglutinogen named C,D, E and c,d,e.the first three are dominant and last three are recessive.discuss

age An extra finger in humans is rare but is due to a dominant gene.
