In A and B we see the number of phenotypes that can be found, in a case of polygenic inheritance, depends on the number of allele pairs involved
<h3>Genetic distance</h3>
The knowledge of the genetic distance between genotypes of a population of interest is important for a breeding program, as it allows the organization of germplasm and a more efficient sampling of genotypes.
<h3>Gaussian</h3>
The normal distribution is a very useful model in statistics, and it would not come as a surprise as the sum of independent effects (or not very correlated effects) should, if there were many of them, normally distribute (always subject to certain assumptions).
With this information we can conclude that in graph <u>A</u> we see a higher frequency of medium-sized individuals, showing zygosity, and in <u>B</u>, <u>heterozygosity</u>.

Answer: True!
Reason: Because monomers are long chains of reapeating subuints in Polymers
Answer:
A. The chromatin near cis-regulatory sequences will be more closed and there will be less transcription.
Explanation:
In the presence of histones, the cis-regulatory sequences of DNA like promoter, enhancers etc. are not exposed. The function of the histone acetyltransferases (HATS) is to cause chromosome decondensation i.e. removal of histones from the DNA so that transcription of the DNA could occur. Histone acetyltransferases (HATS) cause acetylation of lysine amino acid of the histone proteins. Acetyl group is negatively charged so the acetylation of histone proteins leads to the removal of their positive charge which ultimately leads to the decrease in the interaction between N terminal of histones and negatively charged phosphate group of the DNA molecule. As soon as histones are removed from the DNA where cis-regulatory sequences are located, the DNA becomes accessible for transcription.
But here a drug has been added which blocks the activity of histone acetyltransferases (HATS) in cancer cells. So it is quite evident that in these cells, histones will not get removed from the cis-regulatory sequences of DNA so the DNA will be more closer or tightly packed as a result of which less transcription will occur.
Answer: D) Pulmonary and aortic valves.
Explanation
There are two main heartbeats from a healthy heart.
The first beat is called the S1 or the lub, and it occurs when the atrioventricular valves (comprising the mitral and tricuspid valves) close.
The second beat is called the S2 or the dub, and it occurs when the semilunar valves (comprising the aortic and pulmonary valves) close.
Listening for heart beats is an essential part of cardiac auscultation.
