3. You have one copy of each gene from each of your parents.
Some are dominant: TT, Tt
& Some are recessive: tt

4. Vocab words for Thursday
Homozygous = Two copies of the same allele of a trait (AA, aa)
Heterozygous = One dominant and one recessive allele for a trait (Aa)
Phenotype = physical appearance of an organism (observable traits)
Genotype = Genetic make-up of traits, or an entire organism
Dominant = Allele that is expressed as the phenotype in heterozygous pairs (Aa)
Recessive = Allele that is not expressed in heterozygous pairs (Aa)

5. The probability of dominant and recessive traits can be show in a Punnett Square:

7. Step one: Know the parents
Is the parent heterozygous (they carry a DOMINANT and a recessive trait): Tt Or homozygous dominant (they carry two DOMINANT traits): TT Or homozygous recessive (they carry two recessive traits): tt
