True or false<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-1-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p>False. The Hardy-Weinberg equilibrium principle states that in a population, allele frequencies will remain constant from one generation to the next in the absence of evolutionary influences. The equilibrium is represented by the equation:<\/p>\n\n\n\n<p><strong>p\u00b2 + 2pq + q\u00b2 = 1<\/strong><\/p>\n\n\n\n<p>Here, <strong>p<\/strong> and <strong>q<\/strong> are the frequencies of the two alleles (typically dominant and recessive) for a given gene, and p\u00b2, 2pq, and q\u00b2 represent the frequencies of the genotypes (homozygous dominant, heterozygous, and homozygous recessive, respectively).<\/p>\n\n\n\n<p>The equation <strong>p + q = 1<\/strong> is often used to express the relationship between the allele frequencies. This indicates that the sum of the frequency of the dominant allele <strong>p<\/strong> and the recessive allele <strong>q<\/strong> must be 1, as they represent all the possible alleles for a gene.<\/p>\n\n\n\n<p>However, <strong>p q = 1<\/strong> is incorrect because it suggests a multiplicative relationship between the frequencies of the two alleles, which is not a part of the Hardy-Weinberg principle. Instead, the equation for allele frequencies is:<\/p>\n\n\n\n<p><strong>p + q = 1<\/strong><\/p>\n\n\n\n<p>So, while <strong>p<\/strong> and <strong>q<\/strong> represent the frequencies of the two alleles in a population, their sum must be 1, not their product. If the product of <strong>p<\/strong> and <strong>q<\/strong> were equal to 1, it would imply that <strong>p<\/strong> and <strong>q<\/strong> would both have to be 1, which contradicts the concept of allele variation in the population.<\/p>\n\n\n\n<p>In conclusion, the correct equation related to Hardy-Weinberg equilibrium is <strong>p + q = 1<\/strong>, not <strong>p q = 1<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner8-270.jpeg\" alt=\"\" class=\"wp-image-248600\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>The Hardy-Weinberg equilibrium is about p q = 1.
