True and False
A. Multiple independently assorting genes and their alleles can interact to control one train.
B. A single gene and its alleles interact to yield modified mendelian phenotypic ratios
C. Novel phenotypes may be produced as a result of the interaction of multiple genes
D. Gene interaction ultimately results from the interaction of gene products.
Homework Answers
A. Multiple independently assorting genes and their alleles can
interact to control one train.
The answer is True. Those genes are called
epistatic genes.
B. A single gene and its alleles interact to yield modified
mendelian phenotypic ratios
The answer is True. Eg. Petal color in 4'O clock
plant. The dominant and recessive alleles interaction moidifieds
its ratio from 3:1 to 1:2:1
C. Novel phenotypes may be produced as a result of the
interaction of multiple genes
The answer is True.
D. Gene interaction ultimately results from the interaction of
gene products.
The answer is True.

In gene interaction, genes at different loci contribute to the determination of a single phenotypic characteristic. How does gene interaction differ from dominance? In your answer consider: Do genes interact or do gene products interact? How can the different levels of interaction be expressed-molecular, cellular and organismal? Include examples to gene interactions that produce novel phenotypes.
If alleles of different genes always maintain their parental association rather than assorting independently into offspring,...
If alleles of different genes always maintain their parental association rather than assorting independently into offspring, this is because Options: a) Mendel's experiments were flawed. b) they are really alleles of a single gene. c) there was a meiotic error. d) they are very close together on the same chromosome. e) they are on the same chromosome but far apart.

7) In Labrador retrievers, 2 independently assorting genes interact to generate coat color (B, b and E, e). The genotype B_E_ results in black coat; bbE_ results in chocolate coats; B_ee results in yellow coat; and bbee results in yellow coat. If you were a breeder, you might be especially interested in producing black and brown labs, since they might fetch the most money when sold. What proportion of these two phenotypes would you expect from the following crosses? a)...

I have the answers to the two question below. Can you help explain why the answers please. Thanks Considering factors that account for the differences in Gene/ Allelic expression that lead to modidied Mendelian ratios. Tell whether the statements are True and Flase. a. Modified Mendelian ratios do arise as a result of patial expression of alleles in the heterozygote. True b. Typical Mendelian ratios are the result of the simultaneous expression of two alleles in the heterozygote. False c....

1. At least 3 independently assorting loci are known to govern coat color in mice. The genotype C- will allow pigment to be produced by 2 other genes. The cc genotype does not allow pigment production resulting in albino mice. The striped “agouti” hair pattern depends on the genotype A- and the aa genotype is nonagouti. Finally, the color of the pigment may be black (B-) or brown (bb). Five different coat colors may be produced by the action of...

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...

Which of these statements is incorrect? Syntenic genes are located on the same chromosome. Independent assortment results in recombinant chromosomes. You can reliably predict the relative genetic distance from genes’ physical distance on a chromosome. Linked genes are always syntenic. What is the relative genetic distance between two linked genes if the recombination frequency is 0.49? 0.49 cM 4.9 cM 49 cM 490 cM What statement best explains the distortion in Mendelian ratios observed by Bateson & Punnett in 1905?...

4) In this problem we will explore some of the many ways that mutations in two different genes can interact to produce different Mendelian ratios. Consider a hypothetical snail species that has shells that may be fully banded, ventrally banded, or completely unbanded (no bands). Imagine mutations in two different unlinked genes that can, in certain combinations, block the formation of banding, either fully or on most of the dorsal portion of the shell. In principle, there are two different...
