The trait that will be expressed only if two copies of the allele are present.

What is it called when a gene carries two different types of alleles?

What is it called when a gene carries two of the same alleles?

Which of the following is homozygous recessive?

Which of the following is homozygous dominant?

Brown eye color is dominant. Blue eye color is recessive. Select the combination of letters below that would represent a person being a purebred for brown eyes. In other words, which option represents a person having both alleles for brown eyes? (hint: think of capitalization of letters and what is used for dominant vs. recessive).

What is the definition of the phenotype?

What is NOT a possible genotype for someone with type B blood?

A calico cat shows both the traits for orange fur and black fur. What kind of allele expression is this?

The alleles of a gene pair in a heterozygote are both expressed with no blending.

If brown eyes are dominant and blue eyes are recessive, what color eyes do the parents in this Punnett Square have?

Which cross could produce a child with blood type A?

A roan (RW) bull mated with a red (RR) cow. What is the probability or producing a white (WW) cow?

Some flowers are controlled by codominance. Red flowers (RR), blue flowers (BB) and Speckled flowers (RB).

Cross a red flower with a speckled flower. What is the phenotypic ratio?

Law which states that different traits are inherited independently of each other

Law states that 1 allele is more dominant than the other. Recessive allele is only expressed when dominant is not present

If your genotype is Bb, then you can only pass a B or b to your child but you can't pass both.

An organism is a hybrid genotype (Tt) but is appears tall instead of short.

Mendel crossed purebred yellow seeds with purebred greenseeds. Then he self ferilised the F1 progeny to obtain the F2. The statistic analysis of the F2 showed that... (more than one answer might be right)

In dihybrid crosses, the alleles for the two traits segregate independently of each other when gametes are formed. So when looking at a parent with two traits there are four possible combinations when gametes are formed.

The alleles must separate when gametes are formed

Examples include skin color and height (the individual's phenotype exists somewhere along a spectrum)

A father has type AB blood and the mother has type O. What percentage of their offspring would you expect to have?

AB blood type is an example of what type of inheritance? Both alleles show in the phenotype

A single gene has 3 or more alleles. These are called

What type of inheritance is determined by multiple genes and there can be a range of traits?

A woman has type B blood and her husband has type O blood. What must be the woman's genotype, if they have a child with type O blood?

What are the blood types of the possible children that a woman (type O) and man (type AB) can have?

What is NOT a possible genotype for someone with type B blood?

Spider-Man has a genotype Ww and Mary Jane Watson has a genotype ww, what would be the genotypic ratio of their children?

What does it mean to be a "purebred" (select all that apply)
