Meiosis Flashcards
Somatic Cells
Body cells, Diploid cells
Gametes
Sex Cells, These are Haploid
Diploid
2 full sets of chromosomes (2n), A set from mom and a set from dad 2n=46
Haploid Cells
1 full set of chromosomes (n) Only one set that is a combination of chromosomes from mom and dad
Autosomes
Carry traits that make you who you are
Sex chromosomes
Cary traits that make you who you are AND determine your biological sex
Karyotype
A diagram that shows the number and visual appearance of the chromosomes in the cell
2 types of chromosomes
Autosomes and Sex chromosomes
Meiosis
Process of cell division that makes gametes in the gonads
What does Meiosis produce
Haploid sex cells
Sexual reproduction
organisms that reproduce sexually (like humans) fuse the genetic information (gametes) from two parents to produce offspring that are a genetic mixture of both parents.
Fertilization
Actual fusion of egg and sperm
Homologous Chromosomes
Chromosome pairs that have the same type of gene
Sister Chromatides
2 identical copies of the same chromosomes
Meiosis I
separation of Homologous chromosomes
