An autosomal dominant gene is associated with several traits related to the olfactory system. One trait is that people with at least one copy of the dominant allele can smell a specific chemical when it is present. People with two copies of the recessive allele cannot smell the chemical. Being able to smell or not smell the chemical when a person has two copies of the dominant allele is an example of: Codominance Epistasis Expressivity Penetrance Phenocopy The concentration of the chemical that must be present before a person can smell it is an example of:: Codominance Epistasis Expressivity Penetrance Phenocopy

    1.Certain characteristics, like coat color in many animals, is influenced by multiple genes. The phenomenon during which the presence of a homozygous recessive genotype at one locus "overrides" or masks the phenotype that would otherwise be produced by the alleles at another locus (regardless of whether they are dominant or recessive) is called: pleiotropy codominance Punnett effect recessive Epistasis 2. Which of the following would be considered a pleiotropic gene? A gene that-along with several others-influences a single phenotype, such...

    1) Coat color in mice is determined by several independently assorting autosomal genes. Gene A is involved in the distribution of pigment along the hair. A dominant allele (A) produces a hair color called "agouti"--the hair has dark pigment at the base and tip of each hair shaft and yellow pigment in the central portion of the shaft. Homozygous recessive mice (aa) are missing the yellow stripe and thus have solid dark-colored hair. Gene B is involved in the color...

    (3) Some people can taste the bitter compound phenylthiocarbamide while others cannot. This trait is governed by a single autosomal gene; the allele for tasting is completely dominant with respect to the allele for nontasting. Among 1707 Hawaiians tested for the ability to taste, 1326 tasters were found. Assuming that the population is at Hardy-Weinberg equilibrium for this gene and that mating is purely random: a. What are the allele frequencies for the tasting allele T and for the nontasting...

    Human Genetics Although we humans are fantastically made, are quite complex, and our traits are often coded by many genes, some traits are coded by single gene pairs. The following table is a survey to help you determine your genotype, based on phenotype traits. Keep in mind the terms homozygous dominant (AA) will have the dominant trait, homozygous recessive (aa) will have the recessive trait, and heterozygous (Aa) will have the dominant trait. If you have the dominant trait, you...

    You are investigating two traits in fruit flies controlled by one autosomal dominant gene each. The B gene controls for body color (B=black or b=brown), while the r gene controls for body sculpture (R=rugose or r=smooth). After crossing heterozygous rugose black flies with homozygous smooth brown flies, you obtain an F1 generation of 100% rugose black flies. 1. What are the dominant alleles? 2. What are the genotypes of the two parent flies to perform a dihybrid cross? 3. Of...

    Colorium is an autosomal dominant trait in Nutonian flies (identical to earth fruit flies in every way). There are two alleles at this locus: F = Dominant allele; flies with this allele cannot observe the color Fuschia; these flies have the Colorium phenotype. + = Wild type allele; flies who are homozygous for this allele can observe the color Fuschia; these flies do not have the Colorium phenotype. A cross of a true breeding male with Colorium and a true...

    10. Red green colorblindness is an X-linked recessive disease. That means that it is carried on the X chromosome, so men have just one copy of the gene while women have two. In women, both copies must be the recessive disease allele in order to show the disease phenotype, but because men only have one allele, just one recessive allele causes the disease phenotype. Matt and Kate both have normal vision, but Kate's father is colorblind. Use X for the...
