Explain the difference between epistasis end dominance How many loci are involved in each case?

Answers

Answer 1
Answer:

Answer:

Dominance:

Dominance may be defined as the phenomena in which intra allelic genes are involved in the process. The dominant trait hides the expression of the recessive trait. The same alleles of the gene are involved in this expression. Two loci of the same gene are involved in the dominance.

Epistasis:

Epistasis may be defined as the phenomena in which inter allelic genes are involved in the process. The one gene modifies the expression of the other gene. Different gene are involved in this process. Four loci of two different genes are involved in the process of epistasis.

The bamboo population decreases so low that the carrying capacity for pandas becomes zero. O C. The populations of bamboo and pandas follow a cyclical pattern of increasing and decreasing, until one of them becomes extinct O D. The populations of bamboo and pandas both follw a pattern of exponential growth, and then both become extinct​

Aniridia is a human condition in which the eye has no iris. The protein encoded by the gene responsible for aniridia is very nearly identical to the protein product of the fly Eyeless protein. What experiment could provide evidence that the two genes are functionally equivalent?

Answers

Answer:

An Experiment to get proof that the two genes are equivalent functionally will be to introduce the aneroid mutation from the human eye with the condition into the  embryos  of Drosophila (small fruit flies) and look out for the formation of iris.

Explanation:

There exists a medical test called The Invitae Aniridia Test  which can analyze the primary gene associated with aniridia however, in order to provide evidence that these same gene is also present in small fruit flies (a genus of flies called  Drosophila) The method described in the answer above will do.

Which of the following is the functional unit of a myofibril? a. sarcomere
b. myofilament
c. sarcolemma
d. endomysium

Answers

Answer:

Sarcomere

Explanation:

Myofibril is the unit of the muscle cell. The myofibril is rod like in structure and developed by the process of myogenesis in embryo.

Sarcomere is the basic structural unit of the skeletal muscles and shows striations under the microscope. Sarcomere consists of thick and thin filaments of actin and myosin. Different bands like A- band , H-Band, I-Band and Z- line is visible in the sarcomere.

Thus, the correct answer is option (A).

You have been reading for a while and want to rest your eyes and listen to the next section of your chapter. You have finish reading the assignment for the next quiz but want some extra review with flashbacks. You begin reading your E texts with blank letters against a white background but want to try changing the color mode to sepia instead. You have highlighted importing content, and added notes as you read.Now you want to compile and export these notes as a pdf study reference. You’ve highlighted important terms and ideas in your e text . Now you want to hide your highlights as you review for an exam.

Answers

To rest my eyes and listen to the next section of my chapter, I'll consider using text-to-speech functionality. After finishing the assignment for the next quiz, I'll review it with flashbacks to reinforce my understanding. Changing the color mode to sepia can be a soothing option for reading.

For compiling and exporting notes as a PDF study reference, I'd typically use note-taking or document management software. I'd also look for options to export highlights separately.

To hide the highlights during exam review, I'd check if there's a way to turn off the highlight display in my e-text software temporarily. If not, I may consider making a copy of the text without highlights for focused study.

Is there anything specific you'd like to know or discuss further about this?
