State Diffrence btw Synapsis and crossing over.
Answers
Answer:
Synapsis:
The pairing of the homologous chromosomes during the prophase 1 of the meiosis 1 is known as the synapsis.
Crossing Over:
The exchange of the genetic material during synapsis is known as the crossing over.
Synapsis: Synapsis occurs at first.
Crossing Over: Synapsis is followed by crossing over.
Synapsis: Synapsis always occurs.
Crossing Over: Crossing over may occur sometimes.
Synapsis: Synapsis ensures the proper segregation of homologous chromosomes and allows the recombination through crossing over.
Crossing Over: Crossing over allows the variations of alleles in a population through genetic recombination.
Synapsis: Two homologous chromosomes come together during synapsis.
Crossing Over: DNA pieces of the non-sister chromatids are exchanged during crossing over.
Crossing over is an interchange or reciprocal exchange of segment between chromatids of a homologous pair of chromosomes resulting in a recombination of gene.The term crossing over was coined by Morgan 1990.
Synapsis is the pairing of two homologous chromosomes that occur during meiosis. It allows matching up of homologous pair prior to their segregation & possible chromosomal crossover between them. It takes place during prophase 1 of meiosis.
