independent assortment and crossing over

Question 1

independent assortment is when

Answer 1

The alleles of two (or more) different genes get sorted into gametes independently of one another

The allele a gamete received for one gene does not influence the allele received for another gene

Question 2

The alleles of two (or more) different genes get sorted into gametes independently of one another

The allele a gamete received for one gene does not influence the allele received for another gene

why does this happen

Answer 2

This is because homologous chromosomes line up in random orientations at the middle of the cell at metaphase as they prepare to separate, meaning that the same parent cell can produce different combinations of chromosomes in the daughter cells
