a set of true/false questions: Realized heritability may be determined from artificial selection experiments (True/False) Horizontal gene transfer between individuals in a population, while not a mutation, is a source of genetic variation. (true/false) The process of conjugation may introduce new alleles into the recipient strain, altering its genotype. (true/false)

00:01 Vision 1 in turn discusses about the concept that is called as the realized heritability.

00:07 So realized heritability is a feature that pushes a particular trait towards the selection and this in turn can be expressed as hat square and this the formula to calculate realized heritability is that the first one it is the response that is given for a particular selection that is expressed as response to selection and this parameter is in turn divided by another parameter that is called as the selection differential.

00:34 So this intern determines whether a particular triad will get selected when pushed towards the selection.

00:42 So when there is a in the had square in turn it is very, very low.

00:46 This intern indicates that the offspring of the selected parents differ from the original with a slide difference only.

00:53 So there is a small difference only a small difference with regard to the selection.

00:57 And the other one, it is a higher.

00:59 Realized heritability.

01:02 This in turn denotes that when the offspring selected, that is completely differ from that of the actual parent or original population.

01:11 Hence, these are the different measures and this realized headability can also be altered when it is done by an artificial selection.

01:19 Because artificial selection in turn can reduce the number of differences between the original population and also the chosen population because it is artificially decided.

01:29 Hence, with regard to this answer to this question it is true question two discusses about the concept that is called as horizontal gene transfer return as h gt horizontal gene transfer is a mechanism in order to transfer the genetic material from one bacterial population to the another and one of this method is to like one one there are several different methods and most discussed are the three important methods mainly transformation transduction and conjugation.

02:06 So which can be transformation can be written as t and transduction can be written as td and then conjugation can be returned as c.

02:13 All of these are the genetic are the methods in which genetic material can be transferred between two bacterial cell.

02:19 So this is the one which will not give rise to any change.

02:23 So it will not contribute to the factor that is called as mutation.

02:27 That could be a reason for a change in genetic variation.

02:30 Whereas the other possible method that is mutation in turn can result in a genetic variation...
