1. Genetics Notes

2. Law of Segregation
               i.      Mendel didn’t know about chromosomes and genes or meiosis
      ii.      But figured out that there was some factor for each trait
1.    T vs. t
2.    Mendel figured a hybrid had both Tt, but during gamete formation they separated and recombined in fertilization
3.    This concept is the LAW OF SEGREGATION

3. Law of Segregation

4. Law of Independent Assortment
.      Different traits are inherited independently (separately) of one another

5. Incomplete Dominance i. Both alleles contribute to phenotype
  ii.      Mixing of parental traits
1.    ex.  Four O’Clock Flower
a.     Red x White = Pink

6. Meiosis
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
Haploid: 1 set of chromosomes
Diploid: 2 sets of chromosomes

7. Mitosis
Meiosis
How many cells are produced?
Haploid or Diploid
Sexual or Asexual
Cells the same or different?
Check the one that exchanges genetic material.
How many rounds of division?
1 or 2
Check the one that is an exact copy of itself.
Tell me one thing that they have in common.
