Question 18

A pattern of inheritance in a hybrid in which both traits are present but not blended

Answer 18

Codominance

Question 19

The treat that an organism expresses as determined by it’s genotype

Answer 19

Phenotype

Question 20

A Labrador retriever coat color is determined by two different genes what type of inheritance is this?

Answer 20

Polygenic inheritance

Question 21

Human blood involves what type of inheritance.

Answer 21

Multiple alleles

Question 22

A white albino rabbit lacks fur color. It carries the alleles rr. What is its Genotype and phenotype.

Answer 22

Genotype is rr

Phenotype is white fur (fur lacking color)

Question 23

I did if I the example as simple dominance, incomplete dominance, or code dominance. A purebred white sheep is Brad with a purebred black sheep to produce a white limb.

Answer 23

Simple dominance

Question 24

Identify the example as simple dominance, incomplete dominance, or code dominance. A purebred white Poppy is pollinated by a purebred red poppy all of the offspring have pink blossoms.

Answer 24

Incomplete dominance

Question 25

Identify this example as simple dominance, incomplete dominance, or codominant. A mom with type A blood and a dad with type B blood have a child with type AB blood.

Answer 25

Codominance

Question 26

Identify if this is an example of simple dominance, incomplete dominance, or codominant. A purebred P plant with wrinkled seeds is pollinated with a purebred pre-plan with round seeds. All of the offspring have round seeds.

Answer 26

Simple dominance

Question 27

Two Pea plants with yellow peas were crossed and the seeds were planted. Of the hundred offspring 73 had yellow peas and the other 27 had green peas which allele is Dominent

Answer 27

Yellow

Question 28

Summarize Mendels third principle of inheritance

Answer 28

A parent passes each allele to its offspring independently of all other alleles

Question 29

Summarize Mendels second principle of inheritance

Answer 29

For any one character, the two alleles for a parent Jean separate and then combine with the other parents alleles to determine the offspring’s trait.

Question 30

Summarize Mendels first principle of inheritance

Answer 30

1. in across a purebred parents all offspring will show the dominant trait

Question 31

What do we call the change in the ratio of alleles caused by the Environment?

Answer 31

Natural selection

Question 32

What do we call random changes in the ratio of alleles in a population

Answer 32

Genetic drift

Question 33

The process through which organisms with certain adaptations survive to pass on their treats to a greater number of offspring that other organisms do

Answer 33

Natural selection
