CHYS 2P35 Lecture 4: Lecture 4
Document Summary
Father"s sperm + mother"s ovum = zygote with 46 chromosomes in total (these chromosomes are in every cell in our bodies) 23 from each parent for the first 10 days, the zygote just floats in the fallopian tubes, it needs nutrients to grow (coming from the biological mom) used as a defense mechanism. The process by which a cell separates chromosomes in its nucleus into two identical cells. Sections of chromosomes p section, q section 6p22 (allele little section of the chromosome, gene is associated with a learning disability, a mutation doesn"t carry proper instructions) being near-sighted is considered a mutation. Dcdc2 a mutation is related to a particular learning disability. A sperm cell is getting ready to go, meiosis splits into half. One kid could get 50% of this random mix of dad, and 50% of mom. This is important because one kid could get a learning disability and the other kid does not have it.
