Evolution & Genetics Assessment

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

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

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

• hidden allele
• dominant allele
• recessive allele
• present allele

Which of the following genotypes is a purebred?

• Bb
• Gg
• bb
• Dd

Two organisms that are closely related would have

• very similar DNA sequence
• exactly the same DNA sequences
• no proteins in common
• completely different DNA sequence

The bones of the forelimbs of the whale, the human and the bat are very similar. This indicates that they all may

• have descended from a common ancestor

• belong to the same species

• Have to range great distances to eat

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

• Purple
• Green
• GG
• gg

Tt is-

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

Which of the following genotypes is homozygous recessive?

• RR
• Rr
• rr
• None of the Above

The change over time in populations of related species.

• biological evolution
• transition
• variation
• adaptation

A slight difference in an inherited trait between individual members of the same species.

• variations
• adapatations
• homologous structures
• analogous structures
