Before Meiosis Flashcards
What stages occur before meiosis?
early interphase
late interphase
prophase 1
What are homologous pairs?
one chromosome from each parent
same gene but different alleles
What is a chromosome made up of?
chromotaids (the long part) and a centromere that joins the two chromatids
What occurs during early interphase?
6 chromosomes and 3 homologus pairs
diploid 2n
chromatids are not joined at this point (so no double chromosomes)
What occurs during late interphase?
6 (double) chromosomes
3 homologous pairs
diploid 2x 2n
the chromatids are joined together at this point
What happens at prophase 1?
the chromosomes are randomly assorted
nuclear membrane starts to break down
