Question: A botanist studying waterlilies in an isolated pond observed three leaf shapes in the population: round, arrowhead, and scalloped. Marker analysis of DNA from 125 individuals showed the round-leafed plants to be homozygous for allele r1, while the plants with arrowhead leaves were homozygous for a different allele at the same locus, r2. Plants with scalloped leaves showed DNA profiles with both the r1 and r2 markers. Frequency of the r1 marker was estimated at 0.74.The botanist also counted 25 plants with scalloped leaves in the pond.
To calculate inbreeding coefficient from population data, use the following equation:
F = (He - Ho)/He
where He is the number of heterozygotes (2pq x # of individuals in the population) expected in the population and Ho is the number of observed heterozygotes in the population.
What is the inbreeding coefficient F for this population?
Round your initial calculations of p and q to two decimal places; then enter your final answer (F) to two decimal places.
