What major chromosomal event occurs between leptonema and zygonema?
After condensing into long strands in the nucleus during Leptotene/Leptonema Chromosomes line up approximately with each other into homologous pairs. Telomeres cluster at one end of the nucleus and synapsis (pairing together of the homologous chromosomes) takes place in Zygotene/Zygonema.
What 3 things homologous chromosomes have in common?
Homologous chromosome have gene of same character.
Where does recombination of DNA occur?
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA
What Recombination occurs during .?
Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA
In a diploid cell what is the origin of each of the homologous chromosomes?
Homologous chromosomes in a diploid cell come from male and female parents during fertilization. Pairing of these chromosomes takes place during meiosis to interchange the genetic material to facilitate evolution among those organisms.
Why do humans have homologous structured?
For genetic variation to take place
Different alleles of the same gene are found?
at the same place on homologous chromosomes source: Alleles of a gene reside at the same locus on homologous chromosomes.
What happens to each pair of duplicated homologous chromosomes during meiosis 1?
pairing of homologous chromosomes and recombination of genetic material takes place

What phrase is used to describe the chromatids after crossing over takes place and the homologous chromosomes separate?

Where does the crossing over during Snyapsis take place?
it takes place between homologous chromosomes and results in new gene combinations
How does meiosis contribute to the variation in a species?
During meiosis crossing over takes place between homologous chromosomes. Thus genetic material get interchanged and 50 % new combinations are obtained after each meiotic cell division. Thus, meiosis brings heritable variation in the gametes.
