Meiosis II results in four haploid daughter cells, each with the same number of chromosomes. However, each chromosome is unique and contains a mix of genetic information from the maternal and paternal chromosomes in the original parent cell.
How do daughter cells receive both maternal and paternal chromosomes?
In MEIOSIS I , each daughter cell gets EITHER the maternal OR the paternal PAIR of chromosomes. [NOTE: each chromosome is separate. There will almost always be a mix of chromosomes from the mother and father in the entire cell. ... In MITOSIS, each daughter cell gets ONE maternal chromosome and ONE paternal chromosome.
What creates different combinations of maternal and paternal chromosomes?
In this example, there are four possible genetic combinations for the gametes. With n = 23 in human cells, there are over 8 million possible combinations of paternal and maternal chromosomes. ... It is the specific process of meiosis , resulting in four unique haploid cells, that results in these many combinations.
What results in a random mixture of paternal and maternal genetic material in each daughter cell during meiosis?
What results in a random mixture of paternal and maternal genetic material in each daughter cell during meiosis? Random alignment of chromosome pairs during metaphase I . ... Random and results in genetic variability.
What process creates genetically identical daughter cells?
Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. ... These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
What are the maternal and paternal chromosomes?
Maternal chromosomes refer to the set of chromosomes that comes from the female gametes while paternal chromosomes refer to the set of chromosomes that comes from the male gametes. Thus, this is the basic difference between maternal and paternal chromosomes.
How many chromosomes are there in each daughter cell?
At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes . At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.
What is the probability of passing on all paternal chromosomes?
All the chromosomes of maternal origin do not go on one side with all the paternal ones on the other. Maternal and paternal chromosomes are randomly distributed on either side of the metaphase plate. So for each pair there’s a 50/50 chance as to which side the homologs will go on (8.17).
How many genetic combinations are possible per child?
There are 8,324,608 possible combinations of 23 chromosome pairs . As a result, two gametes virtually never have exactly the same combination of chromosomes. Each chromosome contains dozens to thousands of different genes.
What is recombination of gene?
Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles . This recombination process creates genetic diversity at the level of genes that reflects differences in the DNA sequences of different organisms.
What is it called when chromosomes split into daughter cells?
A cell with two pairs of each set of chromosomes is called a [ diploid / haploid ] cell. These cells are typically found throughout the body tissues and are called [ germ / somatic ] cells. ... During meiosis , chromosomes will split into daughter cells randomly, making each gamete unique.
Are somatic cells passed onto offspring?
Somatic Cells
A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent. Mutations in somatic cells can affect the individual, but they are not passed on to offspring .
What is it called when chromosomes split into daughter cells randomly during meiosis?
during meosis , chromosomes will split into daughter cells randomly, making each gamete unique. this is called. genetic recombination.
What is the correct order of steps in the cell cycle?
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage) . The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
How do cells multiply?
Mitosis is when a cell multiplies by spliting into two , to do this there must be enough nutrients and the cell must have undamaged DNA. The cell multiplies its DNA and then through Prophase, Metaphase, Anaphase, and Telophase. Once it goes through this process there is two cells.
What are the 3 types of cell division?
Cells must divide in order to produce more cells. They complete this division in three different ways called mitosis, meiosis, and binary fission .
