Random Independent Produces Genetic Homologous Pair Maternal Paternal

This flashcard explains random independent assortment, emphasizing that the random orientation of homologous pairs on the metaphase plate results in daughter cells receiving any combination of maternal and paternal chromosomes, thereby generating genetic variation.

Random independent assortment: random orientation of homologous pairs on metaphase plate leads to any combination of maternal/paternal chromosomes in daughter cells.

Front Describe the process of random independent assortment and explain how it produces genetic variation.
Back Random independent assortment:
  • Orientation of each homologous pair on metaphase plate is random and independent of any other homologous pair
  • Maternal or paternal chromosomes can end up facing either pole
  • This means that the daughter cells can end up with any combination of maternal and paternal chromosomes hence why it produces genetic variation
