Answer #1

In dragons the fire breathing allele is F. This allele is dominant meaning that when it is present it will always express its phenotype (fire breathing) . By convention the non-fire breathing allele is the recessive allele and will be denoted by small letter: f. This allele will only express it's phenotype when the dominant allele is not present.

So the three possible genotypes and phenotypes of the dragons will be:

1. FF (Homozygous dominant) - Fire breathing  

2. Ff (Heterozygous dominant) - Fire breathing

3. ff (Homozygous recessive) - Non-fire breathing

    For these questions, you are using the A, B, and O to represent the alleles in this example. The ABO blood system works in a Mendelian fashion, but has 3 possible alleles at one locus (A, B, and O alleles). Each person can have only 2 of those alleles in their genotype. A and B are both dominant (and so can be co-dominant), and O is recessive to both A and B. So, for example, if you have B blood...

    Problem Description: A gene with two alleles (e.g. A and a) is responsible for a dominant trait in Hellbenders (Cryptobranchus alleganiensis). AA individuals have a normal phenotype, while those with aa lack the trait. Heterozygotes have phenotypes that are identical to AA individuals. Although aa individuals have lower survivorship (15%) than those with the “normal” trait (35%), they have higher fecundity over their lifetime (100 individuals for aa; compared to 48 for AA and Aa). Assume the allele frequency of...
