Which discovery supports the hypothesis that evolution of the lactase-persistence trait was driven by the use of milk in pastora
V125BC [204]

The lactase-persistence mutations are roughly as old as the oldest milk-holding vessels or pots

lactase persistence:

Lactase persistence is an example of natural selection, which can cause some humans to continue the activity of the lactase enzyme in adulthood also.

The hereditary examinations and studies propose that the established mutation related to lactase persistence began a long time back, in populaces that started domesticating and dairy cultivation during the Neolithic age when pastoralist populaces started to utilize milk for their livelihood. As found and studied that “the lactase-persistence mutations are roughly as old as the oldest milk-holding vessels.” The cultural and social activities of dairying and drinking non-human milk gave an environment wherein lactase persistence was favorable. DNA proof demonstrates that mutation in the lactase gene emerged in these populaces around a similar time.

In addition to mutations, genetic variation can also arise during the formation of gametes during meiosis. During meiosis I, hom
amm1812

Answer:

Crossing over ensures that organisms of the same parents have differences in genetic content making them unique in one way or the other.

Explanation:

This question is describing the process of crossing over, which occurs only during prophase I of meiosis. During the process of crossing over, alleles of a gene are exchanged between non-sister chromatids of homologous chromosomes (mother and father chromosomes).

Hence, a unique GAMETE that has been genetically recombined will be formed. When these gametes are fertilized (egg) or fertilizes (sperm), organisms that are genetically different from their parents are produced. This ensures genetic variation, which is a difference in the genetic content of organisms.

ivanzaharov [21]

The type of relationship that occurs between the clover plants and the bacterias is called mutualism.

<h3>What is Mutualism?</h3>

Mutualism is an ecological relationship between individuals of different species, in which both are benefited by the interaction. As it occurs between individuals of different species, it is a so-called interspecific relationship, and, as it benefits all those involved, it is called a harmonic relationship.
