Homologous chromosomes ANSWER> Chromosomes with the same genes in the same
order
1
, How many rounds of homologous chromosomal replication occurs during meiosis?
ANSWER> One round
When do the chromosomes replicate during meiosis? ANSWER> Before meiosis I
Are the products (cells) of meiosis 1 haploid or diploid? ANSWER> Haploid cells
Are the products of meiosis 2 haploid or diploid? ANSWER> Haploid cells
What's the key event during meiosis 1? ANSWER> (Crossover) Pairing of Homologous
chromosomes
What's the key event during meiosis 2? ANSWER> Sister chromatids separate
Synapsis ANSWER> Pairing of homologous chromosomes (during meiosis 1), makes a
tetrad
Crossover ANSWER> Exchange of genetic material between homologous chromosomes
Tetrad ANSWER> A group of four chromatids formed during meiosis
Why is meiosis called a reduction division? ANSWER> because it reduces the number of
chromosomes to half the normal number so that, when fusion of sperm and egg occurs,
baby will have the correct number. Results in haploid cells
