Which type of reproduction is responsible for genetic variation?

Answers

Answer:

sexual reproduction

Explanation:

Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.

Other reproductions like asexual, budding or fragmentation don't produce genetic variation.

The type of reproduction is responsible for genetic variation is - sexual reproduction.

Sexual reproduction is combining genetic information from two individuals, by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.

Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.

Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.

D)A sample of distilled water

Answers

Answer:

D. A sample of distilled water

Explanation:

You need to have a control sample that hasn't been messed with to see what would happen if you had no reaction to your experiment

A sample is the smaller set of data which a researcher makes use of to complete a research.

As a result of this, we can see that a sample study is the use of these samples to come to a conclusion about the investigation or research which is going on.

Some examples of a sample study include:

Simple random sampling. Systematic sampling. Stratified sampling, etc

Explanation:

If the egg of a particular butterfly has 14 chromosome, then the somatic cells will have same 14 chromosomes.

What are somatic cells?

A somatic cell, also known as a vegetal cell, is any biological cell other than a gamete, germ cell, gametocyte, or undifferentiated stem cell that forms the body of a multicellular organism.

These cells make up the body of an organism and divide via binary fission and mitotic division.

Mitosis is a cell division process that produces somatic cells. They have two copies of each chromosome, one from the mother and one from the father. Diploid cells usually have two copies each of each chromosome.

Mitosis is the method by which one cell splits into two genetically identical daughter cells.

The cell's chromosomes are copied and then distributed evenly between the two new nuclei of the daughter cells during the various stages of mitosis.

Thus, as these are somatic cells, they will have same number of chromosomes.

Answers

Answer:

Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues. In adults most cell division is involved in tissue renewal rather than growth, many types of cells undergoing continuous replacement.

Explanation:

Internal monitors called checkpoints track each step of the cell cycle. In the cell cycle, there are three main checkpoints; one at the end of G1, a second at the transition of G2/M, and a third during the metaphase. Positive molecules of the regulator allow the cell cycle to proceed to the next level.

Mitosis, although continuous process, is conventionally divided into five stages: prophase, prophase, metaphase, anaphase and telophase.
