Genetics Practice
Recall that a dominant allele is typically represented by a capitalized letter. The letter chosen is
usually the first letter of the characteristic. (Example: B =Brown fur) A recessive gene is represented
by the same letter as the dominant gene, but it is not capitalized. (Example: b = white fur)
Using this information complete the following chart on the following chupacabra traits:
Dominant: Dark eyes, Long legs, Brown fur, Wide stripes, Complex Tail,
Recessive: White eyes, Short legs, White fur, Narrow stripes, Simple Tail

Using symbols from the chart above, write the genotypes (LETTERS) for the genes that would be
present in the following individual. This individual is homozygous for each trait.
Dark eyes _________
Short legs _______________
Wide stripes _________________
