Chromosomes, Mitosis, and Meiosis 6.1
2
Autosomes – Chromosomes 1-22
Karyotype – Image of all the chromosomes in a cell Autosomes – Chromosomes 1-22 Sex Chromosomes – #23 Homologous chromosomes – pair of matching chromosomes
3
Somatic cells -Body cells Gametes -Reproductive cells
4
Life Cycle of a cell
5
Diploid Cell – Cell that has 2 copies of each chromosome (2n).
Mom gave Dad gave Chromatid 1 Chromatid 2 You Interphase Asexual reproduction: identical cells Involved in Sexual reproduction: Produces genetically unique cells Results in Diploid cells Results in Haploid cells Mitosis Meiosis Diploid Cell – Cell that has 2 copies of each chromosome (2n). Haploid Cell – Cell that has 1 copy of each chromosome (n).

“Houston, we have touchdown”
Oogonia Diploid cells in ovary of females make eggs Spermatogonia Diploid cells in testies of males produce sperm Meiosis “Houston, we have touchdown”
7
Zygote- A fertilized egg
