During metaphase 1 all 23 maternal chromosomes lined up on one side of the cell would genetic diversity in crease?

No...the chromosomes ate not being crossed over and there would not be any room to fit them all on one side anyways.

How do meiosis and sexual reproduction fertilization produce offspring that differ genetically from the parents?
Meiosis maintains genetic diversity in two ways:1) Genetic recombination: the exchange of genetic material between sister chromatids2) By random assortment of paternal and maternal chromosomes and the alleles of genes they contain.
The process of cell division that creates genetic variety in cells is what?
Genetic variation occurs due to crossing over at prophase 1 and independent assortment of homologous chromosomes at metaphase 1. Both prophase 1 and metaphase 1 are stages of meiosis 1, in which homologous chromosomes are separated.
What event increases genetic diversity during meiosis?
During meiosis 1, a process called crossing over occurs, wherein segments of genes are exchanged between homologous chromosomes. Homologous chromosomes line up or 'cross over' one another to form structures called chaismata. This structural orientation allows the exchange of genetic segments between chromosomes. The crossing over event is the cornerstone of genetic diversity.
Genetic mixing of genes that result from crossing-over?
Recombination is the genetic mixing of genes that result from crossing over.
Why is metaphase important?
Metaphase is important because it involves chromosomes transporting genetic material to the center of a cell before becoming a couple of daughter cells. Mitosis or meiosis would be impossible without this intermediary phase.
Is genetic diversity due entirely to inherited genes on the sex chromosomes?
No, because genetic diversity has nothing to do with the sex chromosomes but is due to crossing-over of chromosomes independent assortment of chromosomes, and segregation of chromosomes

What factors contribute to genetic diversity?
The way the chromosomes line up during meiosis.
Genetic mixing of genes that result from crossing-over?
Recombination is the genetic mixing of genes that result from crossing over.
What event in meiosis leads to genetic variation in organisms?
Genetic crossover occurs, which causes a sharing and transference of genetic information between maternal and paternal copies of chromosomes and further enhances the genetic variability of their offspring.
Why is metaphase important?
Metaphase is important because it involves chromosomes transporting genetic material to the center of a cell before becoming a couple of daughter cells. Mitosis or meiosis would be impossible without this intermediary phase.
What is the first things chromosomes do?
DNA is exchanged between homologous chromosomes in a process called "crossing over" or "genetic recombination," which is important for maintaining diversity in the genetic pool from one generation of individuals to the next.
In a human the 46 chromosomes would be at the equator during?
There won't be more than 23 Chromosomes at any stage unless the individual has a genetic disorder. They align in metaphase during mitosis and meiosis.
What are two ways that sexual reproduction helps create and and maintain genetic diversity?
Sexual reproduction helps create and maintain genetic diversity by: # The independent assortment of chromosomes during meiosis. # The random fertilization of gametes.
Is crossing over a chromosomal abnormality?
No, it is normal for chromosomes to cross over. Crossing over is how we humans have genetic diversity.
