Question

1. crossing-over occurs in

while independent
assortment occurs in
and anaphase i.

1. because of

and
independent assortment in meiosis,
each gamete contains a different set
of dna.

1. independent assortment is the

process where the
move randomly to separate poles
during meiosis.

1. this reshuffling of genes into

unique combinations increases the
genetic
in a population
and explains the variation we see
between siblings with the same

metaphase i genes
chromosomes variation
prophase i anaphase i
recombination

Explanation:

1. Crossing-over (chromosomal exchange) happens in prophase I of meiosis; independent assortment starts in metaphase I.
2. Crossing-over (recombination) and independent assortment create unique gamete DNA.
3. Independent assortment involves random movement of chromosomes to poles.
4. Reshuffling increases genetic variation in populations.

Answer:

1. prophase I; metaphase I
2. recombination
3. chromosomes
4. variation
