You generated a plant that is heterozygous for three quantitative trait loci (qtls). in the heterozygous state, each locus has one allele that contributes one dose of trait (pigment) and another allele that does not contribute a dose to the trait; genotype: r1/r1; r2/r2; r3/r3. if you testcross this plant (by r1/r1; r2/r2; r3/r3 all "0-dose" alleles) what distribution of pigment doses would be observed in the progeny?

Benito is doing research on the effects of florida's elevation on its climate. his notes include the following: 1. the average elevation of florida is 30 m above sea level. 2. the highest point in florida is britton hill, which is 105 m above sea level. 3. the change in temperature from 0 m to 1,000 m is 7 °c. what can benito conclude about the effects of florida's elevation on its climate? a.) florida typically experiences cold temperatures and temperature changes within a narrow range. b.) florida typically experiences cold temperatures and temperature changes within a broad range. c.) florida typically experiences warm temperatures and temperature changes within a narrow range. d.) florida typically experiences warm temperatures and temperature changes within a broad range.
