What is a phenotype?

• The genetic make up (code)

• The physical trait

An allele whose trait only shows up when no dominant allele is present

• Hidden allele

• Dominant allele

• Recessive allele

• Present allele

What does heterozygous mean?

• An organism that has the same genes for a trait (TT or tt)

• An organism that has different genes for a trait (Tt)

• When neither gene is fully dominant; offspring is a mixture of both

• The different forms of a trait (hair color--> brown, blonde, red

What is the definition of genotype?

• The physical expression of a trait

• The genetic combination of alleles

• The genes on a DNA strand

• Homozygous

• Hetrozygous

• Protein

• Chromosome

Having two different genes for a trait (sometimes called hybrid)

• Protein

• Homozygous

• Heterozygous

• Genotype

G = green, g = yellow
The genotype for a yellow plant is...

• GG
• Gg
• gg
• all of the choices result in yellow
