Transcribed Image Text:Determining if a plant population is Evolving
One way to test whether evolution is occurring in a population is to compare
the observed genotype frequencies at a locus with those expected for a non-
evolving population based on the Hardy-Weinberg equation. In this exercise,
you'll test whether a pea plant population is evolving at a locus with two
alleles, Cand C, that affect chlorophyll production and hence leaf color.
Experimental Set-up:
Students planted soybean seeds and then counted the number of seedlings
of each genotype at Day 7 and again at Day 21. Seedlings of each genotype
could be distinguished visually because the C° and C' show incomplete
dominance: C°C® seedlings have green leaves, C°C" seedlings have green-
yellow leaves, and C'C" seedlings have yellow leaves.

Interpret the Data
1. Use the observed genotype frequencies from Day 7 data to calculate
the frequencies of the C allele (p) and the C allele (q). (Remember
that the frequency of an allele in a gene pool is the number of copies
of that allele divided by the total number of copies of all alleles at that
locus.)
