What is the relationship between alleles, genotype, and phenotype?
Write down an example of a genotype that is:
Homozygous dominant
Homozygous recessive
Heterozygous

2. Traits Observable characteristic
Determined by protein shape which is determined by our genes that we get from our parents

3. Genetics
Study of how traits are passed from parent to offspring

5. Mendel’s experiments Traits are observed separately from each other
Chose traits that had two distinct phenotypes
Took data, saw a consistent pattern

6. Law of Segregation
Organisms donate only one copy of each gene in their gametes. The two copies of each gene segregate, or separate during meiosis
Organisms inherit 2 copies of each gene, one from each parent A a
Meiosis A a A a
