Chapter 8.11 - 8.14 Flashcards
somatic cells
every cell in your body except sex cells
germ cells
start as diploids but become haploid gametes via meiosis
go through meiosis to create sex cells
autosomes
non-gender determining chromosomes
sex chromosomes
determine gender and some other traits
diploid
a cell containing a full set of chromosomes (46 chromosomes)
haploid
a cell containing one copy of each chromosome or a single set of unpaired chromosomes
homologous chromosomes
one chromosome from mom, one from dad, contain the same trait if different variations
sexual reproduction
the fusion of two gametes resulting in an offspring that is a genetic mixture of both parents
fertilization
the fusion of haploid egg and haploid sperm
zygote
fertilized diploid egg
meiosis purpose
turn a diploid to haploids for sexual reproduction; create gametes
mitosis purpose
growth and regeneration of new cells
meiosis I
homologous chromosomes separate
meiosis II
sister chromatids separate
