Mendelian Genetics

Genotype: TT

• homozygous dominant

• homozygous recessive

• heterozygous dominant

Another word for homozygous is...

• true breeding

• hybrid

• heterozygous

• dominant

If a pea plant were homozygous recessive for height, how would its alleles be represented?

• TT
• Tt
• tt
• tT

If green is dominant over purple, then what is the genotype for this individual?

• Purple
• Green
• GG
• gg

Which of the following best describes a GENOTYPE?

• The allele/genetic makeup of an organism.
• The physical expression of a trait.

this image is an example of

• codominance
• dominance
• incomplete dominance

A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:

• all black
• all white
• all gray
• speckled black and white

What you see, or the physical appearance.

• Genotype
• Phenotype
• Homozygous
• Heterozygous
