Gregor Mendel experimented on the following

• rats

• mice

• flowers

• peas

Mendel took over true breeding pea plants, this means that

• the plants were all homozygous dominant

• the plants were all homozygous recessive

• the plants would produce identical offspring if allowed to self-pollinate

• the plants would produce identical offspring if allowed to pollinate with other pea plants

Variations of a gene that can vary between individuals

• genes

• chromosomes

• traits

• segments

Mendel studied

• 2 traits of pea plants

• 7 traits of pea plants

• 1 trait of pea plants

• he only studied genotypes

The original pair of plants before breeding

• P (parental generation)

• F0 (parental generation)

• F1 (parental generation)

• F1 (first generation)

The direct offspring of original breeding plants

• F1

• F2

• O1

• O2

Some alleles are dominant while others are recessive

• Allele principle

• principle of dominance

• principle of genetics

• principle of inheritance

When Mendel crossed F1 plants he noticed

• heterozygous traits from the parental generation

• homozygous dominant traits from the parental generation

• homozygous recessive traits from the parental generation

• he made F2 plants

The oldest generation

• F2

• F1

• F0

• P
