Question
In the Paraguayan Easter Atlantic Forest, a mating between a homozygous black yaguarundi and
a homozygous blond yaguarundi will produce all brown yaguarundi offspring. When these
brown F₁ yaguarundies are mated, their offspring consists of 2 white, 31 black, 154 brown, and
17 blond yaguarundies.
A) Name what genetic interaction or ratio (depending on the ratio expected) may be occurring in
this population?
B) What are the observed and expec phenotypic ratios for these F2 progeny?
C) Use a Chi-squared analysis to test your hypothesis (set a = 0.05). Be sure to report all values
used in your comparisons (p-values, critical values, alpha value, df, etc), your hypothesis, and
show your work.
