AP meiosis Flashcards

9226851622	crossing over	Process in which homologous chromosomes exchange portions of their chromatids during meiosis.	0
9226851623	diploid	(genetics) an organism or cell having two sets of chromosomes or twice the haploid number	1
9226851624	disjunction	the separation of homologous pairs of chromosomes following meiotic synapsis	2
9226851625	fertilization	Process in sexual reproduction in which male and female reproductive cells join to form a new cell	3
9226851626	gamete	Sex cell	4
9226851627	gametogenesis	Formation of gametes	5
9226851628	gonad	ovaries and testes Glands related to sexual characteristics and the processes involved in reproduction	6
9226851629	haploid	An organism or cell having only one complete set of chromosomes.	7
9226851630	homologous pair	Similarly constructed chromosomes that have the same shape and contain genes for the same traits	8
9226851631	meiosis	A type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.	9
9226851632	nondisjunction	Error in meiosis in which homologous chromosomes fail to separate.	10
9226851633	oogenesis	Egg production	11
9226851634	ootid	final product of oogenesis; following a period of maturation, becomes an ovum	12
9226851635	ovum	A mature egg cell	13
9226851636	polar bodies	the 3 smaller cells produced in oogenesis that will degenerate	14
9226851637	somatic cell	Any of the cells of a plant or animal except the reproductive cells.	15
9226851638	sperm	Male sex cell	16
9226851639	spermatogenesis	Formation of sperm	17
9226851640	synapsis	Pairing of homologous chromosomes	18
9226851641	tetrad	structure containing 4 chromatids that forms during meiosis	19
