5987123040	eggs	the type of gamete found in females	8
5987123041	ovaries	meiosis occurs in this organ in females	9
5987123042	testes	meiosis occurs in this organ in males	10
5987123043	prophase I	the phase in meiosis where the chromatin condenses into chromosomes and forms homologous pairs.	11
5987123044	prophase I	the phase in meiosis where crossing over occurs	12
5987123045	crossing over	the exchange of genetic material between non sister chromatids of homologous chromosomes	13
5987123046	non sister chromatids	crossing over occurs between these	14
5987123047	metaphase I	the phase in meiosis where homologous chromosomes line up in the middle of the cell	15
5987123048	independent assortment	the phenomenon where homologous chromosomes align along the metaphase plate independently of one another	16
5987123049	anaphase I	the phase in meiosis where homologous chromosomes are pulled to opposite sides	17
5987123050	telophase I	the phase in meiosis where two new haploid nuclei are formed	18
5987123051	metaphase I	the phase in meiosis where independent assortment occurs	19
5987123052	diploid	two sets of chromosomes	20
5987123053	haploid	one set of chromosomes	21
5987123054	prophase II	the phase in meiosis were the chromatin condenses into chromosomes	22
5987123055	metaphase II	the phase in meiosis where the chromosomes line up in the center of the cell	23
5987123056	anaphase II	the phase in meiosis where the chromosomes are split into chromatids	24
5987123057	telophase II	the phase in meiosis where two new nuclei are formed, resulting in four haploid cells	25
5987123058	s phase	the phase of interphase where the DNA is duplicated	26
5987123059	g1 phase	the phase of interphase where the cell grows	27
5987123060	g2 phase	the phase of interphase where the cell continues to grow and correct errors in DNA replication	28
5987123061	zygote	a fertilized egg, it is diploid	29
5987123062	budding	a type of asexual reproduction performed in yeast where a new identical organism buds off an anatomical point of the original organism	30
5987123063	fertilization	the joining of an egg and a sperm	31
5987123064	parthenogenesis	a type of asexual reproduction where an unfertilized egg develops into an identical female offspring	32
5987123065	sprouting	a type of asexual reproduction where an identical offspring develops from a shoot of a root or a stump	33
5987123066	nondisjunction	occurs in anaphase 1, when a homologous chromosome fails to separate, or in anaphse 2, when a chromosome fails to separate	34
5987123067	down syndrome	trisomy 21, a child is born with mental retardation and elfish features	35
5987123068	edward's syndrome	trisomy 18, a child is born with severe defects, most die within the first year	36
5987123069	turner syndrome	a child is born with a single x chromosome, develops as a female, is small in stature, and is sterile	37
5987123070	klinefelter's syndrome	a child is born with xxy, develops as a male with subtle female characteristics such as wide hips and enlarged breasts	38
