Multiple Choice

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

Multiple Choice

incomplete dominance means that there traits are,,,

• expressed equally
• dominant
• recessive
• blended

Multiple Choice

Which of these Punnett squares represents a cross between a homozygous dominant parent and a heterozygous parent?

Multiple Choice

Which of the following genotypes is dominant?

• AA

• Aa

• aa

• both AA and Aa

Multiple Choice

This is an example of ___________?

• Incomplete dominance
• Co-Dominance

Multiple Choice

Rabbits may have long or short ears. A long-eared, homozygous dominant rabbit is mated with another long-eared, but heterozygous rabbit.

If L represents the dominant trait allele and l represents the recessive trait allele, select the alternative below that best illustrates the genotypes of the offspring.

• all long-eared

• LL and ll

• LL and Ll

• long-eared and short-eared

Selective breeding is intentional!

Multiple Choice

TRUE or FALSE: Selective breeding happens naturally over time

• TRUE

• FALSE

Multiple Choice

Which stage of the selective breeding process comes first?

• Only let individuals with the desired characteristics reproduce

• Select the offspring with the desired characteristics

• Select the individuals with the desired characteristics

• Repeat the process until the entire group have desired characteristics

Multiple Choice

Which of these is a common example of selective breeding?

• Chickens that produce lots of eggs

• Crops that catch diseases

• Plants that produce fewer tomatoes

• A, B and C are all examples of selective breeding

Multiple Choice

How can farmers best use selective breeding to increase apple production?

• By limiting the number of trees growing so they can have more space.

• By choosing trees that are the largest in size.

• By increasing the amount of water and fertilizer the trees receive.

• By choosing trees that consistently have the most apples.

Multiple Choice

Problems with animals that are selectively bred include:

• Being more disease resistant

• Producing more meat

• Being more likely to suffer from genetic disease

• Being more genetically diverse
