If the plant morphs you study are going to respond to natural selection, they much vary in phenotype, and this variation must be heritable. this variation must also result in differences in relative fitness among the morphs. for example, the size of leaves a plant produces could affect relative fitness by determining how much energy a particular plant collects. the amount of energy collected would affect investment in reproduction. leaf size is a measurable trait. below, suggest three other measurable plant traits that could affect relative fitness and explain them briefly.:

Climate like that in the sahara desert have the fastest rates of weathering

Researchers studying a small milkweed population note that some plants produce a toxin and other plants do not. they identify the gene responsible for toxin production. the dominant allele (t) codes for an enzyme that makes the toxin, and the recessive allele (t) codes for a nonfunctional enzyme that cannot produce the toxin. heterozygotes produce an intermediate amount of toxin. the genotypes of all individuals in the population are determined (see chart) and used to determine the actual allele frequencies in the population. is this population in hardy-weinberg equilibrium? a) yes. b) no; there are more homozygotes than expected. c) no; there are more heterozygotes than expected. d) more information is needed to answer this question.
