When Mendel cross pollinated a pure breeding tall plant with a pure breeding short plant, what were the results? (HINT: make a Punnett square to see results)

• all short plants

• all tall plants

• some tall and some short

When Mendel allowed a hybrid plant to self pollinate, what were his offspring results? (HINT: make a Punnett square to see results)

• 50% tall, 50% short

• all tall

• all short

• 75% tall, 25% short

Homozygous means

• Two alleles(letters) for a trait that are the same

• Two alleles (letters) for a trait that are different

• No alleles for a trait

A trait that overpowers or overshadows another trait is considered to be

• recessive

• hybrid

• uncommon

• dominant

TT is

• Homozygous

• Heterozygous

• Hybrid

• common

Hybrid means that an organism has

• two of the same type of allele for a trait

• two different alleles for a trait

• Two uppercase letters

• Two lowercase letters

The physical appearance of a trait is known as that organism's

• genotype

• genes

• phenotype

• phenomes

The passing of traits from parents to offspring is known as

• genetics

• allele

• gene

• heredity
