what is the evolutionary significance of Diplotene stage
Answers
diplotene. a stage of MEIOSIS near the end of Prophase 1, in which the CHROMATIDS become separated (except at the CHIASMATA), and the chromosomal material is contracting. The chiasmata indicate that CROSSING OVER is taking place.
plz mark me brainlist dear
The evolutionary significance of diplotene stage is that there occurs a crossing over of genes from 2 different cells or chromosomes at this stage, that aids in the formation of a single zygote from 2 different gametes.
EXPLANATION:
Since the mixing of gene takes place, the inferior combination of genes gets deleted and the superior combination of genes which is required for existence gets selected. Due to this selection and deletion of the required genes it becomes an ideal process in the evolution .
