How is the diploid chromosome number restored after halving in meiosis?

Which of the following best describes how a diploid number of chromosomes is restored?

Which of the following best describes how the diploid number of chromosomes is restored in the offspring of these organisms? … Meiosis produces daughter cells with half the number of chromosome sets of the parent cell; therefore, the parent cell must be diploid.

What does 2n 14 mean?

Hi Unique7. 2n=14, which means that this organism has 7 pairs of chromosomes(7*2=14). We can also write that as n=7.

What process restores the diploid chromosome number?

The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition.

How is diploid status restored in haploid cells?

During meiosis the cell produces gametes, or germ cells, each containing half the normal or somatic number of chromosomes. This condition is called haploidy. When two germ cells (e.g., egg and sperm) unite, the diploid condition is restored.

What is the result of the process of crossing over during metaphase I?

When chromatids “cross over,” homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I.

What is the diploid stage of a plant that follows fertilization called?

In alternation of generations, what is the diploid stage of a plant that follows fertilization called? The sporophyte is the diploid, multicellular stage of the plant that produces haploid spores by meiosis.

When the sperm and egg nuclei unite the chromosome number is restored to diploid the fusion of sperm and egg is called?

The cells that produce sperm in humans contain 46 chromosomes. … When two haploid gametes fuse during fertilization, a full complement of chromosomes is restored; the diploid cell that results is called a zygote.

Which event leads to a diploid cell in a life cycle?

Fertilization between the gametes forms a diploid zygote. The zygote will undergo many rounds of mitosis and give rise to a diploid multicellular plant called a sporophyte.
