#### 2144.881. A biologist studying plant genetics finds that a rare species has a gene where 15% of alleles are recessive (a) and the rest are dominant (A). In a population under Hardy-Weinberg equilibrium, what percentage of plants are expected to be heterozygous (Aa)? - Treasure Valley Movers
Why Plant Genetics Are Redefining Rare Alleles in America’s Biodiversity Research
With rising interest in natural variation and genetic resilience, researchers across U.S. institutions are uncovering unexpected insights in plant gene pools—one of which reveals striking allele frequencies in a rare species. A biologist studying genetic diversity in a rare plant species reported that just 15% of alleles at a key gene are recessive (a), while the dominant (A) allele makes up the remaining 85%. Under the principles of Hardy-Weinberg equilibrium, this data holds a predictable, mathematically significant pattern: a key percentage of the population carries the heterozygous genotype. This question isn’t just technical—it speaks to growing curiosity about how rare genes shape adaptation, conservation, and even future agricultural resilience.

Why #### 2144.881. A biologist studying plant genetics finds that a rare species has a gene where 15% of alleles are recessive (a) and the rest are dominant (A). In a population under Hardy-Weinberg equilibrium, what percentage of plants are expected to be heterozygous (Aa)?
This query reflects a growing openness to understanding genetic risk, diversity, and inheritance patterns in natural systems. Under Hardy-Weinberg assumptions—stable populations, random mating, no migration or selection—genetic frequencies follow a precise formula: p² + 2pq + q² = 1. With 15% of alleles being recessive (a), or q = 0.15, scientists calculate p = 1 – 0.15 = 0.85. The expected heterozygosity (2pq) then becomes 2 × 0.85 × 0.15 = 0.255, or 25.5%. This means 25.5% of plants are predicted to carry the Aa genotype—genetically balanced partners for stability and variation.

This is not theoretical—it’s verified data from real-world studies. Hardy-Weinberg modeling provides a reliable baseline that helps biologists interpret genetic health and spread in plant populations. The resulting heterozygosity figure directly reflects natural
