Which of the following statements is true? Acquired mutations are passed down from parent to offspring. Mutations are the most fundamental way to add new genes to a gene pool. Hereditary mutations are caused by external factors, such as radiation. Only somatic mutations are important to evolution because they can be inherited.

Answer 1

Answer:

Answer: Mutations are the most fundamental way to add new genes to a gene pool.

Explanation:

A mutation is either permanent or temporary changes that may occur in the DNA sequence of the organism that makes up a gene which is the functional unit in the organism. These mutations will add genetic variations in the gene pool of the population. Those mutations which are hereditary which means they can be transmitted from parents to offsprings are called as germline mutations.

Acquired (somatic) mutations are those mutations which occur's during a persons life. These mutations occur due to ultraviolet radiations. These mutations occur in the somatic cells not in the germ cells therefore, these cannot be passed from one generation to the next.

Answer 2

Answer: Acquired mutations are passed down the line.

Define the term hominin.

Answers

$\red{Answer:-}$

✭The Hominini, or hominins, form a taxonomic tribe of the subfamily Homininae ("hominines"). Hominini includes the extant genera Homo (humans) and Pan (Chimpanzees and Bonobos), but excludes the genus Gorilla (gorillas).

✭The term was originally introduced by John Edward Gray (1824), long before any details on the speciation of Pan and Homo were known. Gray's tribe Hominini by definition includes both Pan and Homo. This definition is still adhered to in the proposal by Mann and Weiss (1996), which divides Hominini into three subtribes, Panina (containing Pan), Hominina ("homininans", containing Homo "humans"), and Australopithecina (containing several extinct "australopithecine" genera).
