Question 9 1 pts Why are inherited forms of cancer autosomal dominant but not fully penetrant? Even if the mutation is inherited, a loss-of-funciton mutation ipmscting one allele is not expressed The inherited allele is dominant at the cellular level, but might not be expressed depending on genetic background Most inherited mutations are recessive at the cellular level Sporadic, but not inherited forms of cancer forms of cancer are caused by somatic mutation Question 10 1 pts Select true statements...
What term is used to express the idea that several genes exert influence over the same characteristic? Select one: a. terminal interaction b. transformation c. co-adhesion d. coextension e. gene interaction A condition in which one gene pair masks the expression of a nonallelic gene pair is called ________. Select one: a. recessiveness b. dominance c. codominance d. epistasis e. additive alleles One result of X-linkage is a crisscross pattern of inheritance in which sons express recessive genes of their...
DO THEM ALL AND BE CLEAR Question 11 pts When Mohan and Begum matted and had cubs, all cubs were what coat color(s)? 3:1 orange to white 1:1 orange All orange coated 2:1 orange to white Flag this Question Question 21 pts One outcome of the blending model of inheritance would be that there would be no phenotypic variation left within a species over time Evolution would proceed more quickly only some traits could deb inherited only continuously variable traits...
1. Animals can teach us genetics. Match Codominance Show a dominant and recessive relationship _An allelic series A dominant homozygote is lethal Coat coloration is determined by 2 genes Shows variable expressivity A qualitative, or continuous, trait involving polygenes Females mosaics for X-linked heterozygous color genes A. Manx cat B. Coat coloration rabbits C. Labrador retriever dogs D. Piebald spotting in beagles E. A and B blood alleles F. A and O blood alleles G. Calico cat H. Height of...
1) Select the true statements about dominant and recessive genes, assuming complete penetrance of the genotype. Circle all that apply. (1.5) For an offspring to be phenotypically dominant for a trait, at least one parent will show the trait. For an offspring to be phenotypically recessive for a trait, at least one parent will show the trait. In incomplete dominant or codominant traits, heterozygotes will have a different phenotype than either homozygote. If both parents show a recessive trait, then...
You are breeding a species of mountain lion (2n); you cross a true breeding male that has straight yellow fur with a true breeding female that has curly red fur. The offspring have curly orange fur; based on your results, what is the mode of interaction between the alleles? Select one: a. Curly fur is dominant to straight fur and yellow fur colour is co-dominant to red b. Curly fur is dominant to straight fur and yellow and red fur...
help 11) In a triploid cell with 4 chromosome triplets (3n = 12), how many sister chromatids will be found in a nucleus at prophase of mitosis? A) 12 B) 24 C) 6 D) 36 12) In birds, sex is determined by a ZW chromosome scheme. Malos aro ZZ and females are ZW. A recessive lethal allele that causes death of the embryo is sometimes present on the Z chromosome in pigeons. What would be the sex ratio in the...
