Question 1

mitosis

Answer 1

asexual reproduction. diploid daughter cells, divide one time, two different cells. Prodcues cells for growth and healing, parents are somatic cells, 2 identical cells made, during metaphase sister chromatids line up, mutation is the only source of variation

Question 2

meiosis

Answer 2

cell didvision to create gametes

Question 3

uniqe trates of meiosis

Answer 3

daughter cells are haploid and gametes, produces reporocudtive cells, 4 different cells are made, divides two times, crossing over can rearange chromosomes, greater variety in offspring, daughter cells are haplid and genuinely unique, fertilization

Question 4

haploid

Answer 4

one copy of chromosomes, gametes, cells are identical

Question 5

diploid

Answer 5

2 copies of each chromosome, somatic cells, cells have homologous chromosomes

Question 6

fertilization

Answer 6

sperm joing w/ and egg ( sperm+egg =zygote)

Question 7

syanpsis

Answer 7

pairing of homologous chromosmes

Question 8

crossing over

Answer 8

occurs in prophase 1 of meiosis, homologous pairs swap pieces of chromosomes
