the centromeres that join the chromatids split, allowing sister chromatids to separate and become individual chromosomes.
anaphase
100
at the end of meiosis the cell is said to be..... (a single set of chromosomes)
haploid
100
type of cells involved in meiosis
gametes
100
punnett squares can be used to predict what?
possible genotypes
200
process by which a cell divides into two new daughter cells.
cell division
200
the chromosomes line up accross the center of the cell
metaphase
200
a stucture thats is formed when each chromosome pairs with its corresponding homologous chromosome
tetrad
200
how many times do the cells divide in one round of the cell cycle in mitosis? what about meiosis?
1 and 2
200
who invented the punnett square?
gregor mendel
300
each pair of chromatids is attached at an area called the?
centromere
300
the chromosomes become visible. the centrioles separate and take up positions on opposite sides of the nucleus.
prophase
300
how many phases are in meiosis?
69........ just kidding 8
300
how many identical cells result from mitosis?...meiosis?
2 and 4
300
what does a capitol letter represent?
dominant trait
400
the series of events that cells go through as they grow and divide.
the cell cycle
400
The chromosomes begin to disperse into a tangle of dense material. A nuclear membrane reforms around each cluster of chromosomes. Then the cytoplasm divides making two new sister cells.
telophase/ cytokinesis
400
as homologous chromosomes pair up and form tetrads in meiosis 1, they exchange portions of their chromatids in a process called?
crossing-over
400
how do the gametes divide? mitosis or meiosis?
meiosis
400
if you have a dominant trait and a recessive trait together what is that called?
heterozygous
500
a specific characteristic, such as seed color or plant height.
trait
500
a fanlike microtuble structure that helps separate the chromosomes
spindle
500
how many copies of each gene are in a diploid organism just after meiosis 2
2
500
what is the fifth phase of meiosis?
prophase 2
500
an organism that has two identical alleles is said to be what?
