A Sexually Reproducing Species of Algae Has Been Engineered to Produce

question 11

Multiple Choice

A sexually reproducing species of algae has been engineered to produce biofuels with varying yields. A colony with the highest yield is stimulated to reproduce with a colony with the lowest yield and the resulting F¹ progeny are allowed to grow. Yields among the F₁ generation have a variance of 7.8 g². The F₁are allowed to mate and the resulting progeny are sampled and found to have a variance of 9.1 g². Assuming that the F₁ progeny are genetically uniform, determine the broad sense heritability (H²) and interpret if genetic heritability is low or high.

• A) H² = 0.86, genetic variability is high
• B) H² = 0.17, genetic variability is low
• C) H² = 0.14, genetic variability is high
• D) H² = 0.14, genetic variability is low
• E) H² = 0.86, genetic variability is low
