Fraternal twins, while conceived at the same time, are not genetically identical.

Which statement best explains why these siblings are genetically different from each other?

A.One chromosome from each pair randomly passes to the sex cells during meiosis and leads to differences between the siblings.

B.One chromosome from each pair randomly passes to the sex cells during fertilization and leads to differences between the siblings.

C.Mutations occur during meiosis and lead to differences between the siblings.

D.Mutations occur during fertilization and lead to differences between the siblings.

Answers

Fraternal twins are not genetically identical because one chromosome from each pair randomly passes during meiosis and leads to differences between the siblings. Meiosis involves independent segregation of sex chromosomes.

Meiosis is a type of reductional cell division by which a parent cell produces four daughter (gametes) cells having half the genetic material.

Fraternal twins occur when two egg cells are released by the mother, which are fertilized by a different sperm.

During meiosis, sex chromosomes are separated and segregate in a random manner in daughter (sex) cells.

Why is it that dominant diseases are not as common as recessive ones?

Answers

Answer:

Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.

Why is it necessary for there to be variation in population in order for evolution by natural selection to occur?

Answers

Answer:

There needs to be variations in population in order for natural selection to occur because the entire point of evolution by natural selection is only the best variations will survive. So if there were no variations then there would be no natural selection because the animal's survival rate would be the same no matter how many times they reproduce because there are no different variations being introduced into the species. However, if there are variations then the animal's survival rate could be impacted because of the variations, for example, white mice would be easier to find for predators on a dark surface, while a darker mice would be harder to find for predators on a dark surface, thus, allowing the darker mice to prevail as they have a higher survival rate and the species will slowly evolve into the darker mice. But, if there were no evolution, in this case, then no matter what happens, the white mice would not be able to evolve into a darker mice because there are no such thing as variation. That is why it is necessary for there to be variation in order for evolution by natural selection to occur.

Which of the following ecological levels does not describe interacting biotic and abiotic factors in an area?

A. Biome
B. Community
C. Ecosystem
D. Habitat

Answers

Answer:

habitat

Explanation:

The ecological levels do not describe interacting biotic and abiotic factors in an area's habitat. The correct option is D.

What is a habitat?

A habitat is a place where physical or biotic factors are presented. This is a place where all the factors are present to live a species with all suitable conditions.

Habitat of different species is different. They live in their suitable habitat to grow and reproduce accordingly. If a species is moved from its habitat, then it may have difficulties in surviving.

So habitat is not a place where all biotic and species abiotic factors are present, it is a place where all living factors are present that are necessary for the living of a person. So, it is not the ecological level of  interacting biotic and abiotic factors in an area

Thus, the correct option is D. Habitat.
