Tampa Bio exam 1 with complete solutions.
A human autosomal recessive trait appears in 1 in 100 births. What percent of people are homozygous dominant for this gene? 81% As a mechanism of evolution, natural selection acts on variants within populations and ultimately leads to different species. This was proposed by Darwin A population of geese has two color phenotypes, brown and gray. Color is controlled by a single gene, with the brown allele dominant. A random sample of 250 geese finds that 210 are brown. What percentage of geese are heterozygous? 48% In a research study, seed production was measured for a plant that has variation in flower petal size. The researchers hypothesized that larger petals would better attract pollinators and result in higher fitness. Does the data support this hypothesis? A table with 4 columns. The row headers are average seed number and relative fitness. The first column header is blank. Small petals Medium petals Large petals Average seed # 20 25 15 Relative fitness 0.8 1.0 0.6 No, because plants with small and medium petals had higher relative fitness For a gene with two alternative alleles, A (with a frequency of p) and a (with a frequency of q), the term in the algebraic form of the Hardy-Weinberg equilibrium for the heterozygote genotype frequency is 2pq
