1. Law of Segregation: The two alleles for a trait
separate when gametes (eggs and sperm) are
formed.

3. Notes: Mendel’s Laws
1. Law of Segregation: The two alleles for a trait
separate when gametes (eggs and sperm) are
formed. Therefore, a parent passes on only
one allele for each trait to each offspring.

2. Law of Independent Assortment: Genes for
different traits are inherited independently of
each other.

5. Notes: Mendel’s Laws
2. Law of Independent Assortment: Genes for
different traits are inherited independently of
each other. Example: Seed color and flower
color are inherited separately. Law is only true
if the genes are far apart in the genome.

6. Homo/Heterozygous
• Homozygous = the two alleles for a trait are
the same

7. • Homozygous = the two alleles for a trait are
the same
• Heterozygous = the two alleles for a trait are
different

heterozygous
