Answer: The principle of original horizontality provides the basis for the law of superposition.

Explanation:

The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

what does the term 2pq represent in the hardy-weinberg equation? the frequency of homozygous recessive individuals the frequency
Nostrana [21]

The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.

<h3>What is Hardy-weinberg equation?</h3>

This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:

p² + 2pq + q² = 1

where

p² is dominant homozygous frequency (AA)

2pq is heterozygous frequency (Aa)

q² is recessive homozygous frequency (aa).

The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.

Identify the inheritance mode of each condition by using the labels to complete the table. labels can be used once, more than on
yan [13]
Since no table is given, I will explain how genes are inherited. After Mendel’s discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. This is an example of the law of inheritance. The genes that are passed down from the parents are being shared by the offspring. It can be shown if the trait is recessive or dominant from the parents’ gene. <span>Chromosomes are inherited from the parents. One chromosome from each of 23 pairs came from each of the parents. The two chromosomes of a pair (except for the sex chromosomes) contain the same genes, but the genes have small differences. The X and Y Chromosomes determine the organism’s sex. One chromosome pair - the sex chromosomes - is unique. Typically females have two X chromosomes and males have an X and a Y. Mothers always pass an X chromosome on to their children. Whether the father passes on his X chromosome (leading to a pair of X chromosomes) or his Y chromosome (making a mixed set) determines your sex. </span>
