- Pedigree Analysis Is a Basic Method in Human Genetics Pedigree analysis permits all of the following except: a. an orderly presentation of family information b. the determination of whether a trait is genetic c. the determination of whether a trait is dominant or recessive d. an understanding of which gene is involved in a heritable disorder e. the determination of whether a trait is sex-linked or autosomalFor each phenotype below, list the genotypes (remember to use the letter of the dominant trait) Curly hair is dominant to straight hair. . ____ straight ____ curly ____ curlyWhat is a Punnett square used for? Group of answer choices To see the possible genotypes of the offspring The solve complex mathematical equations To determine which genetic disease you may have To determine the phenotypes of two parents
- ________ are important to assess because they can modify gene expression. Environmental effects Environmental effects Genotypic variations Genotypic variations Phenotypic variationsThe characteristics that genes express, whether they are physical, behavioral, or biochemical, are a person's __________. Group of answer choices a.phenotype b.penetrance c.haplotype d.genotypePenetrance and expressivity are related but can be distinguished easily because: penetrance affects genotype; expressivity affects phenotype penetrance affects phenotype; expressivity affects genotype penetrance is a quantitative term; expressivity a qualitative term penetrance is a qualitative term; expressivity a quantitative term
- Match each individual on the left with the correct genotype on the right. (not all categories need to be used)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 husbandWhich of the following occurs when the phenotypic effect of one gene contributes to the phenotypic effect of another gene? Qualitative Epistasis Quantitative Additive
- Which of the following terms is the most broad? a phenotype b character c traitMatch the statement with the method for finding QTLs. Crosses are made between two strains that have different alleles for multiple markers Scans the whole genome in search for associations between markers and specific phenotypes tests two alleles that differ between the twoparents of the mapping population may sample a large number of individuals for the trait A. Both B. GWAs C. QTL mappingUse Chi-square to test which of 2 possible ratios is the most probable ratio of progeny kernels. Use this information to determine the cross type and parental genotype.
