Wednes-Day 1
Bio- HW: Outline of Section 10.2 is due on Thursday.
we drew out and discussed karyotypes, which are pictures of the homologous pairs of chromosomes found in the nucleus of a somatic/body cell. We saw how to determine the sex of a person from the karyotypes by focusing on the sex chromosomes: females have matching X chromosomes whereas males have an X and a much smaller Y sex chromosome.
We discussed the difference between a small genetic point mutation and a much larger scale chromosomal mutation.
We focused on the change in chromosome number caused by NONDISJUNCTION during either meiosis I or meiosis II. The resulting gametes, if viable, can unite with the opposite sex cell and for offspring with greater or fewer than the diploid number of chromosomes.
Chem 7/8/9 - we prepped for the upcoming Equilibrium exam by going over each problem type and reviewing some common errors/traps.
