ANTH 105 Lecture 99: ANTH105 Unit 1 Study Guide Part 2
● Somatic cells: Ordinary cells (Red blood cells, White blood cells, nerve cells, etc…)
○ Gametic cells: Eggs and Sperm
○ Mitosis: Cell division of somatic (body) cells
○ Meiosis: Cell division resulting in gametes
○ Haploid (n): The gametes (eggs and sperm) have 23 unpaired chromosomes
○ Diploid (2n): There are 23 pairs of chromosomes in somatic cells (46
chromosomes)
○ Homo sapiens (know n and 2n for our species) Humans (46 chromosomes, 23
pairs)
○ Fertilization/zygote/monozygotic twins/dizygotic twins
○ Gregor Mendel and Mendelian genetics: Be able to do a simple cross for an
autosomal trait and a simple cross for a sex-linked trait
○ Punnett Square
● Gene
○ Genome: All the genes in a given species or individual
