☆ bio unit 6: meiosis

how many cells does meiosis produce?

4 genetically different cells (these cells are haploid)

whats a haploid cell?

cell that only has one chromosome (n)

whats a diploid cell?

cell that has 2 sets of chromosomes

what is the name of the daughter cells during meiosis

gametes (sperm and egg)

why is an organisms diploid cell always even

Because there is always one from mom and one from dad

duing fertilization how many how many haploid cells make one diploid cell

whats crossing over?

Crossing over is when the alleles switch places on the homologous chromosomes 

how does dna mutations or replication errors create genetic variety

causes changes in dna

whats independent assortment?

random assortment of chromosomes which causes different combinations of gametes 

how does crossing over create genetic variety?

creates brand new hybrid chromosome

whats non-disjunction?

non- disjunction is where chromosomes fail to separate correctly during meiosis resulting in extra or fewer chromosomes in a gamete
