Answer #1

Epistasis

Epistasis is non allelic interaction between alleles at different gene loci. Alleles (epistatic) at one gene locus mask the effect of alleles at other gene locus (hypostatic).

Codominance is the type of inheritance in which two alleles are equally dominant over each other and heterozygotes show a variegated phenotype.

Dominance is the type of condition in which one allele is completely dominant over the other allele which is recessive.

Please give a good rating.

Genomic imprinting is an example of a. pleiotropy. b. heterogeneity. c. epistasis. d. differential gene expression. e. a phenocopy. Please briefly explain the correct answer and why it is true. Also If you could explain why it wouldn't be epistasis as I am having a hard time understanding what it is.

Consider a hypothetical quantitative weight trait affected by five loci. Assume complete dominance at all loci, and no epistasis. The independent effect of each dominant allele is +8 lb and the independent effect of each recessive allele is -2 lb. The population mean for the trait is 500 lb. a. If an animal is heterozygous at all loci, and the environmental effect is -12 lb, what are the values for the animal’s breeding value, genotypic value, gene combination value, and...

In golden retrievers, the D/d gene codes for an enzyme that produces a pigment. The dominant allele (D) results in a golden pigment, while the recessive allele (d) codes for red pigment. Additionally, the V/v gene produces a transport protein responsible for depositing the pigment produced by D/d into the hair. When the dominant V allele is present, the color expressed by D/d will be deposited and the dog will be that color (golden or red). However, allele v is...

What is the difference between reproductive cloning and therapeutic cloning? Group of answer choices Therapeutic cloning supplies cells for repair of diseased or injured organs, whereas reproductive cloning produces a cloned organism. Reproductive cloning uses pluripotent cells, whereas therapeutic cloning does not. Reproductive cloning uses embryonic stem cells, whereas therapeutic cloning does not. Therapeutic cloning uses nuclei of adult cells transplanted into enucleated nonfertilized eggs. A mutation that prevents the addition of the 5’cap would most likely have what effect?...

We have a population of snakes. They are either all black or black with red stripes. We make the following crosses to help us determine the gene interaction: A cross between the solid black snakes and the striped snakes results in a 1:1 ratio of solid black to striped snakes among the offspring. A cross between two striped snakes results in progeny in the ratio of 2 striped for every 1 solid black. Assume that these outcomes are manifested by...
