When corn plants are too tall, they lodge (topple over) prior to harvest. This is bad since the grain is often lost when it cannot be picked up off of the ground by mechanical harvesters. You have a high-yielding strain of corn, but the plants often lodge. You want to estimate broad-sense heritability for % lodging in corn. You start by mating two inbred lines to produce an F1 generation. The F1 was allowed to intermate to produce an F2 generation. The variances for each generation are given below: Variance of inbred line 1 = 311
Variance of inbred line 2 = 333
Variance of F1 = 316
Variance of F2 = 1153
1. What is the phenotypic variance?
2. What is the environmental variance?
3. What is the genetic variance?
4. What is the broad-sense heritability?

Drag each tile to the correct box. the body monitors the levels of oxygen in the blood to regulate breathing. isabel is running in a marathon and is near the finish line. she feels out of breath. how will her nervous system work to generate a reaction? arrange the tiles in chronological order. isabel's breathing rate increases. sensory receptors in the arteries detect low oxygen levels. the brain sends signals through motor neurons. sensory neurons generate an impulse. the central nervous system relays an impulse to certain brain regions.
