If two heterozygous dogs had a litter, what is the phenotype ratio of dominant traits to recessive traits?
What is 3:1?
Following a codominant inheritance pattern, if two roan cows with roan coats (RW) are crossed together; what is the percent chance they have white coats?
What is 25%?
What phase in meiosis does crossing over occur?
What is prophase I?
What are the bonds that hold two DNA strands together?
What are Hydrogen Bonds?
What is the law called, where the inheritance of alleles is not affected by one another?
What is the law of independent assortment?
In humans blood type is determined by multiple allele and codominance. If a man with blood type AB has a child with a woman with type O blood. What possible blood types would be possible for their children?
What are Type A and Type B?
After meiosis, cells are considered diploid or haploid?
What is haploid?
Using Chargaff's base pairing rule, if a molecule of DNA has 33% Guanine (G); what is the percentage of Thymine (T)?

In dogs, pointy ears are determined by the dominant allele "E" and floppy ears are determined by the recessive allele "e". Make a key using this information.
Pointy Ears = E_
Floppy Ears = ee
In a pedigree, if there is a skip in a generation; what does that mean about the inheritance pattern of a trait?
What is recessive?

What is 50%?
In humans, hemophilia is a x-linked recessive disorder. Using this information make a key.
Hemophilia = X^a X^a & X^a Y
What is crossing over? How does it impact the haploid cells formed?
What is exchanging homologous chromosomes and creates genetic variation?
