This flashcard explains how genetic variation arises in meiosis through crossing over (Prophase I) and independent assortment of homologous chromosomes (Metaphase I) and sister chromatids (Metaphase II).
This flashcard details the sources of genetic variation during meiosis: crossing over in Prophase I and independent assortment of homologous chromosomes in Metaphase I and sister chromatids in Metaphase II.
| Front | Meiosis genetic variation |
|---|---|
| Back | prophase 1 - crossing over (swapping of alleles) between homolgous chromosomes , chromosmes visible and unorganised metaphase 1 - independent assortment OF HOMOLOGOUS CHROMOSOMES anaphase 1 - seperates homo chromsomes but no splitting of centromere metaphase 2 - independent assortment of sister chromatids anaphase 2 - sperates sister chromatids and splitting of centromere |
