Gregor MendelThe Father of Genetics

• Noticed inheritance traits were passed done from
  generation to generation
• Worked with peas.

Law of Dominance

Gene Sequence of DNA that codes for a particular
traitAllele Alternative forms of a gene
Humans are diploid therefore we have ___ copies
of each gene, and thus ___ alleles.Dominant
Alleles Determine the expression of a trait
(upper case letter) Recessive Alleles Are
overruled by the dominant allele (lower case
letter)

Genotype The alleles an organism
contains.Phenotype The observable traits that
arise because of the interaction between genes
environment.
Homozygous Genotype in which both alleles are
the same.Heterozygous Genotype in which both
alleles are different.
10
Mendels Law of SegregationAlleles separate
during meiosis.A gamete will receive one allele
or the other, but not both.
11
Mendels 2nd Law Law of Independent
AssortmentAlleles of different genes assort
independently of one another during meiosis.
