Difference between synapsis and crossing over
WebDuring synapsis, the chromosomes in the cell come together to form tetrads. When they are in tetrads, chiasmata occurs and during the crossing over, genetic information is swapped between the ends of the chromosomes. When the cells eventually divide into 4 cells, each cell has a new variety of genetic information. WebA) Each diploid cell has eight homologous pairs of chromosomes. B) The species is diploid with 32 chromosomes per cell. C) A gamete from this species has four chromosomes. D) The species has 16 sets of chromosomes per cell. A) Each diploid cell has eight homologous pairs of chromosomes.
