1
Q
What is recombination
A
a process by which pieces of DNA are broken and recombined to produce new combinations of alleles in haploid cells & thus increases the genetic diversity of potential offspring
2
Q
What is a result of recombination?
A
alleles are swapped between non-sister chromatids
3
Q
How are chromosomes connected during synapsis?
A
by a protein-RNA complex called the synaptonemal complex
4
Q
What does the chiasma do?
A
hold the homologous chromosomes together as a bivalent until anaphase I
Chiasmata formation between non-sister chromatids can result in the exchange of alleles
5
Q
When are chiasma formed?
A
in prophase 1
6
Q
What are recombinant chromosomes?
A
These chromosomes that consist of genetic material from both homologues
