- A heterozygote has _____. a. only one of the various forms of a gene b. a pair of identical alleles c. a pair of contrasting alleles d. a haploid condition, in genetic termsThe young woman shown at right has albinismvery pale skin, white hair, and pale blue eyes. This phenotype is due to the absence of melanin, which imparts color to the skin, hair, and eyes. It typically is caused by a recessive allele. In the following situations, what are the probable genotypes of the father, the mother, and their children? a. Both parents have normal phenotypes; some of their children are albino and others are not. b. Both parents and all their children are albino. c. The mother is not albino, the father is albino, and one of their four children is albino.A sex-influenced trait in humans affects the length of the index finger. A short allele is dominant in males and recessive in females.Heterozygous males have an index finger that is significantly shorterthan the ring finger. The gene affecting index finger length is locatedon an autosome. A woman with short index fingers has childrenwith a man who has normal index fingers. They produce five children in the following order: female, male, male, female, male. Theoldest female offspring has one daughter with a man who has normal fingers. The youngest male among the five children has childrenwith a woman with short index fingers; they have two sons. Drawthe pedigree for this family. Indicate the phenotypes of every individual (filled symbols for individuals with short index fingers andopen symbols for individuals with normal index fingers)
- The pedigree shown here involves a trait determined by a singlegene (affected individuals are shown in black). Which of the following patterns of inheritance are possible for this trait?A. RecessiveB. X-linked recessiveC. DominantD. Sex-influenced, recessive in malesE. Sex-limitedOne form of red-green color blindness is an X-linked recessive trait. A heterozygote woman has children with a normal man. List the gene or genes involved and define all allele symbols.Which of the following describes a linkage group?

- Which of the following inheritance patterns results in a phenotypic ratio of 1:2:1 in a monohybrid cross? Mendelian inheritance pattern Epistasis Incomplete dominanceRecessive alleles may be expressed in a child if they are inherited ... (Choose all that apply) Group of answer choices [ ]: from a parent that has undergone radiation treatment [ ]: from neither parent [ ]: from one parent [ ]: from both parents [ ]: from the mother on the X-chromosomeA human disease known as cystic fibrosis is inherited as a recessive trait. Two unaffected individuals have a child who has the disease. What is the probability that their next two children will NOT have the disease?
- A sex-influenced trait in humans is one that affects the length of the index finger. A “short” allele is dominant in males and recessive in females. Heterozygous males have an index finger that is significantly shorter than the ring finger. The gene affecting index finger length is located on an autosome. A woman with short index fingers has children with a man who has normal index fingers. They produce five children in the following order: female, male, male, female, male. The oldest female offspring marries a man with normal fingers and then has one daughter. The youngest male among the five children marries a woman with short index fingers, and then they have two sons. Draw the pedigree for this family. Indicate the phenotypes of every individual (filled symbols for individuals with short index fingers and open symbols for individuals with normal index fingers).A healthy couple had their first child affected by cystic fibrosis. Their next three sons were not affected by this disorder. The couple is expecting another child and wishes to know the probability (odds) that this child will be: Not affected if the three brothers are homozygous dominant. Not affected if three unaffected brothers were determined by DNA typing to be carriers. Not affected if she (he) has one affected and five unaffected sisters. Draw pedigree of the family described in c.Curly hair is due to a dominant allele in humans. Straight hair is a recessice allele. the heterozygous condition produces wavy hair, a. phenotype that appears as a blend of the two alleles. This is an example of which of the following patterns of inheritance. a) Simple dominant b) Sex linkage C) Multiple allele d)Incomplete dominance
