Per 2 M2L1 Inheritance

Which of the following is NOT an example of a trait?

• eye color

• ear shape

Bird A has a genotype bb for bill length, and Bird B is BB. The bills of their offspring would be:

• long in 100% of the offspring.

• short in 100% of the offspring.

• long in 50% of the offspring.

• short in 75% of the offspring.

chromosomes from one parent.

• True

• False

Passing of traits from parent to offspring is ________________.

• phenotype

• heredity

• genotype

• genetics

A florist has one kind of plant that usually has red flowers (the dominant trait), but sometimes has white flowers (the recessive trait). If she crosses plants A and B as shown here, 50% of the offspring will have red flowers.

• True

• False

A heterozygous orange-flowered plant is crossed with a homozygous purple-flowered plant. If orange is a dominant allele and purple is recessive, what color ratio will the flowers of the offspring plants have?

• 1 purple : 3 orange

• 4 purple : 0 orange

• 2 purple : 2 orange

• 0 purple : 4 orange

What model can be used to show traits and help determine genotypes of genetically related family members over several generations?
