Meiosis is a form of cell division which is used in sexual reproduction. In other words, it is the process of making sperm/egg cells in genetic material. There is "meiosis I" which separates the homologues and then there is "meiosis II" which separates the sister chromatids. In meiosis I there are four stages to the division process: Prophase (which is where the homologue chromosomes start to condense), Metaphase (which is where the chromosomes begin to align in the center of the cell), Anaphanse (which is the when the chromasomes start to separate in half) and Telophase (where the resulting chromosomes begin to break off into two separate cells). Meiosis II has a very similar process which ultimately divides the two newly separated cells into a total of four cells (all with their own variation of genetic material). Be sure not to confuse this process with "mitosis", which is the cell division and production process that occurs in asexual reproduction.
Meiosis is the cell division of gametes (sex cells). These gametes have half the original number of chromosomes so when the parents reproduce to form a zygote, the offspring will obtain half of their genetic make up from each parent.
for humans 23 chromosomes from each parent (total of 46, 1/2 from each)
Genetical material is rearranged in meiosis through crossing over.
Genetic material is passed down from parents to offspring by DNA. The DNA copies itself and the number of chromosomes is split in the half from 46 to 23 chromosomes.
Because the crossover occurs during this period, new genes come together and some separate.

What are characteristics passed from parent to offspring called?
genetic traits
How is the genetic material of a parent inherited by offspring in sexual reproduction?
The most common answer to this question is heredity.
Asexual reproduction and sexual reproduction differ in all but what ways?
Asexual reproduction is the process in which a single cell or set of cells produces offspring that inherit all their genetic material from one parent and sexual reproduction needs two parents to produce offspring, the offspring inherits genetic material from both parents.
In what type of cell division does the chromosome number reduce by one half and gametes form?
Meiosis produces gametes which have half the number of chromosomes that other cells of the body have.
Is Edward's syndrome caused by a recessive gene?
Edward's syndrome is not technically recessive or dominant, because it is not caused by a single gene. Rather it happens due to a trisomy of chromosome 18 (or just of a part of said chromosome). Parent's may be healthy and still have offspring with the syndrome not because its recessive, but because the trisomy arises during meiosis of the gametes. Whatever happens to the gametes affects only the offspring not the carrier parent.
How does meiosis contribute to the genetic traits of a ReeBop offspring?
Meiosis is a type of cell division that produces gametes with half the genetic material of the parent cell. This leads to genetic variation in the offspring due to the random assortment of genes and crossing over of genetic material during meiosis. This diversity in genetic traits is essential for the ReeBop offspring to inherit a unique combination of traits from the parents.
Offspring that result from meiosis and fertilization each have?
Offspring that result from meiosis and fertilization inherit half of their genetic information from each parent. This process ensures genetic diversity and variation in the offspring. Meiosis is responsible for producing gametes with half the number of chromosomes, while fertilization combines the genetic material from two parents to create a unique individual.
The passing of genetic material from parent to offspring is?
true
What happens to the genetic material from each parent before sexual reproduction can occur?
each parent must reduce his/her genetic material by half in a process called meiosis.
What proportion of each parent plant's genetic material does each offspring plant have?
Each offspring plant receives 50% of its genetic material from each parent plant. This is because offspring inherit one set of chromosomes from each parent during sexual reproduction.
How are mutations passed down from parent to offspring?
Mutations are passed down from parent to offspring through the genetic material, specifically the DNA. Mutations can occur spontaneously or be inherited from a parent, and they can be passed down to future generations through the transmission of genetic material during reproduction.
Variation of offspring of sexually reproducing organism is the direct result of?
Variation of offspring in sexually reproducing organisms is mainly due to genetic recombination during meiosis, which leads to unique combinations of genetic material being passed on to offspring from their parents. Additionally, mutations can also contribute to variation by introducing new alleles into the gene pool.
How do multicellular organisms reproduce?
Multicellular organisms reproduce sexually by the combination of genetic material from two parent organisms through processes like fertilization. This allows for genetic diversity and variation in offspring.
How does a daughter cell compare to the parent cell after undergoing meiosis?
They have 1/2 the genetic material of the parent cell.
What is a function of chromosomes?
A chromosome is transferred from parent to offspring and its purpose is to transport genetic material to the cell of the offspring
What is the difference between asexual reproduction and meiosis?
Asexual reproduction produces offspring that are genetically identical to the parent, while meiosis is a type of cell division that produces gametes (sex cells) with half the number of chromosomes. Asexual reproduction does not involve the fusion of gametes, while meiosis involves the combination of genetic material from two parents to create genetic diversity in offspring.
How much of each parent-plants genetic material does each offspring have?
hhh
