The genotype AA is Homozygous or Heterozygous? Why?
The F1 generation is
The 1st generation of offspring or the 1st Filial generation
True or false? The phenotype determines the genotype.
FALSE: The GENOTYPE determines the PHENOTYPE.
What is the phenotypic ratio for a cross between
TT x Tt?
[Mendel's observations for plant height: T is dominant for tall, t is recessive for short]
SHOW YOUR WORK
100% Tall
The genotype Tt is Homozygous or Heterozygous? Why?
Heterozygous because alleles are different
Genes expressed by PHYSICAL traits
When Mendel crossed his parent generation, all of the offspring from F1 gen were...
Heterozygous Dominant, all Tall, or all Tt
What is the genotypic ratio for a cross between
Tt x Tt?
[Mendel's observations for plant height: T is dominant for tall, t is recessive for short]

Dominant
What is Genotype?
The genetic makeup for trait(s)
This Law states that the alleles of a gene will be sorted into gametes independently of one another.
The law of Independent assortment
