Usimov [2.4K]

Answer:

C) 19.7%

Explanation:

The new population distribution after climate change wiped out homozygous recessive dinosaurs is:

AA = \frac{4}{4+32}=\frac{1}{9}

Aa = \frac{32}{4+32}=\frac{8}{9}

The percentage of offspring of this new population that are homozygous recessive is given by:

P(Aa\ x\ Aa) = \frac{8}{9} *\frac{8}{9} =\frac{64}{81} \\P(aa) = \frac{1}{4}\\P(Aa\ x\ Aa) \cap P(aa) = \frac{64}{81}*\frac{1}{4} =0.197=19.7\%\\

19.7% of these newborn dinosaurs died
