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>
The nail matrix is the root of the nail from which keratinized cells grow. It <span>is the formative layer of cells at the base of the </span>fingernail or toenail. <span>This tissue consists of rapidly dividing skin cells that soon fill with the protein keratin. Hope this answers the question.</span>

Answer: Sexual reproduction
Explanation:
First, you should understand that mutation (an change in the base-pair sequence of the genetic material, DNA) is the original source of all genetic variation; as such whatsoever will alter the frequency of alleles, even if it is evolution, it relies on mutation.
In contrast, sexual reproduction does not change the frequency of alleles in the gene pool, rather it ensures constancy through the meiotic cell division process
Answer:
Option B. compounds
Explanation:
Compound is a type pure substance which is formed when two or more than two elements combine together chemically in a fixed ratio. It is represented by a chemical formula. Chemically combine means the elements present in the compound make bonds in order to hold each other. So they are not separated by physical methods. It is separated from one another by chemical methods.
