The correct answer is A) Generates new combinations of alleles upon which selection can act.

Explanation:

In biology, there are two main kinds of reproduction: sexual and asexual. Asexual reproduction occurs when there is only a parent involve and this divides, splits or similar to form new cells or organisms that are genetically identical to the parent. On the other hand, in sexual reproduction, there are two parents involved, usually from opposite sexes and the alleles of both are combined in the offspring. The main advantage or benefit of sexual reproduction is that it involves the combination of alleles which means genetic variation, this makes the population able to adapt and evolve as selection acts and also makes a population less vulnerable to diseases. Thus, a benefit of sexual reproduction is that "Generates new combinations of alleles upon which selection can act".

Draw the phases of mitosis of a cell that contains four chromosomes as its diploid or 2n number

anastassius [24]

Answer:

Please find the diagram attached and explanation below.

Explanation:

Mitosis is a type of cell division that forms two genetically identical cells. It involves four stages viz; prophase, metaphase, anaphase, and telophase.

Considering a diploid (2n) cell with four (4) number of chromosomes.

Prophase- four duplicated chromosomes condense and pair up.

Metaphase- four chromosomes line up at the cell plate or equator in order to get separated.

Anaphase- the sister chromatids are pulled apart by the spindle microtubules

Telophase: the chromosomes recoil and organelles form at opposite poles of the cell.

At the end of cytokinesis, which is division of the cytoplasm, four chromatids are present in each daughter cell. The chromatids becomes individual chromosomes that retain the diploid (2n) chromosome number of four.
