Study the Punnett Square below to answer the following question.
What is the missing parental genotype?
Albinism is a recessive condition.
Which circle graph shows the genotype probability of the offspring when an albino female mates with a male that is heterozygous for the albinism trait?
* use the alleles A and a in your Punnett Square
(1 point for selecting the right answer choice, 1 point for correctly setting up your Punnett Square with all the possible genotypes filled in)
Mice have two unlinked allele pairs that affect fur color. The table shows how allele pairs affect fur color. The term “agouti” describes fur with pigmentation that changes in each hair from the shaft to the tip, giving the fur a banded appearance. Mice with the homozygous recessive allele pair are albino, regardless of the second allele-pair combination.
What is the probability of albinism (only albinism) in the offspring of a cross between two mice with AaBb alleles?
Match the vocabulary terms with their definition.
| Draggable item | arrow_right_alt | Corresponding Item |
|---|---|---|
Genotype | arrow_right_alt | The physical trait a person shows. |
Phenotype | arrow_right_alt | A genotype that contains one dominant allele and one recessive allele (Bb). |
Homozygous / Pure | arrow_right_alt | The two alleles (letters) for a given trait (BB, Bb, or bb). |
Heterozygous / Hybrid | arrow_right_alt | A genotype that contains two alleles that are either both dominant or both recessive (BB or bb). |
In pigeons, Checkered Wings are dominant to Striped Wings.

The following cross between two pigeons is performed:
Which genotype is NOT possible in the offspring produced by the cross?
