LO 79 Explain that a phenotype might be monogenic at the molecular level, but polygenic at the organismal level. What is true about the phenotypic expression of a gene? Genes can code for mRNA One gene can be responsible for part of an organismal trait One gene can be singly responsible for a organismal trait Genes can be expressed as structural proteins One gene can code for more than one molecule

I have a biology question, this is a matching question, which is only used once: The phenotype of the heterozygote is a blending of the phenotypes of both homozygotes. One allele masks the expression of the only other allele for the trait. One gene pair will interact so as to control the expression of a second gene pair One example is the ABO blood group system. When 3 or more pairs of genes control the expression of a trait. matched with: multiple alleles incomplete dominance polygenics dominance epistasis

You are examining the gene expression patterns of twins. Which of the following do you expect? Group of answer choices Older identical twins will have more similar expression patterns than similarly aged fraternal twins Younger identical twins will have less similar expression patterns than older identical twins Newborn identical twins will have very different patterns of gene expression Gene expression patterns in identical twins is not related to age
1. In dogs, brown or black coat color is determined by a single autosomal gene with brown (b) being recessive to black (B). A separate gene called extension with alleles e and E also influences color. ee is epistatic black and brown. Dogs that are homozygous for the extension (e) allele have yellow coat color regardless of other genes. The presence of a single E allele allows black or brown to be expressed. Trixie, dog with yellow coat color, is mated to Mansfield, a dog with black coat color, and the puppies are produced in the following ratios: ½ yellow 14 black 1/4 brown What were the genotypes of Trixie and Mansfeild?
1 pts The pedigree below shows the expression of Huntington's disease in a family. Huntington's disease is a fatal genetic disorder that causes the progressive breakdown of nerve cells in the brain. It deteriorates a person's physical and mental abilities usually during their prime working years and has no cure. Huntington's is inherited as a dominant allele (H). Examine the pedigree below and determine the genotype for individual "2" DODO0O 2. O HH O Hh О h O either HH or Hh
Genomic anticipation refers to observations that a genetic disorder occurs at an earlier age in successive generations, whereas genetic imprinting occurs when gene expression varies depending on parental origin.
