Mendelian Genetics

What did Mendel call the two kinds of traits exhibited by the pea plants (one coming from the father, one from the mother)?

• Genesis
• Elective traits
• Alleles
• Quadrants

What do we call the result of the genotype (for example, the color of the peas)?

• Visible traits
• Physiotrait
• Genotype 2
• Phenotype

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

• Purple
• Green
• GG
• gg

Another word for homozygous is...

• purebred
• hybrid
• heterozygous
• dominant

Tt is-

• homozygous dominant
• homozygous recessive
• heterozygous
• none of these

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

• TT
• Tt
• tt
• tT

Which of the following best describes a GENOTYPE?

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

The letters on the TOP AND SIDE of a punnett square represent ______________.

• The combination of alleles in offspring.
• The possible alleles given by the parents following meiosis.
• The genotype and phenotype of offspring.
• The results of genetic mutations in offspring.

What is the predicted percentage of homozygous recessive offspring in this cross?

• 0%

• 25%

• 50%

• 75%

Why do we see only tall plants in the second generation?

• The gene for tall height is dominant
• The gene for short height is dominant
• The gene for tall height is recessive
• The parents did not have the tall gene
