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 are chromosomes restored?
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. During reproduction, when the sperm and egg unite to form a single cell, the number of chromosomes is restored in the offspring. …
How is the diploid condition restored in the next generation?
Fertilization, the joining of two haploid gametes, restores the diploid condition. … The gametes are produced from diploid germ cells, a special cell line that only produces gametes. Once the haploid gametes are formed, they lose the ability to divide again.
What process restores the chromosome number?
Sexual reproduction includes two distinctive processes: The production of haploid gametes, such as sperm and ova, which involves the specialized nuclear division called meiosis. The fusion of gametes at fertilisation, which results in the restoration of the diploid number of chromosomes.
What process restores the human diploid chromosome number of 46?
Replication occurs prior to mitosis to produce gametes and fertilization restores the diploid number.
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.
How is the normal number of chromosomes restored?
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.
How is the diploid chromosome number restored after halving in meiosis?
a. The restoration of the diploid chromosome number after halving in meiosis is due to fertilization.
What happens to chromosomes during meiosis?
Meiosis is a series of events that arrange and separate chromosomes and chromatids into daughter cells. During the interphases of meiosis, each chromosome is duplicated. … The first separates homologs, and the second—like mitosis—separates chromatids into individual chromosomes.
