Chi-square test result (critical value = 3.14, observed = 6.79):<\/strong><\/h3>\n\n\n\n<p><strong>Correct answer: <em>The hypothesis can be rejected.<\/em><\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Explanation<\/strong><\/h3>\n\n\n\n<p>In meiosis, <strong>prophase I<\/strong> is a crucial stage where homologous chromosomes pair up closely to form tetrads. This allows for <strong>crossing over<\/strong>, a process where genetic material is exchanged between <strong>homologous chromosomes<\/strong>, not non-homologous ones. This mixing of genes increases genetic diversity. The statement claiming that crossing over happens between non-homologous chromosomes is false, since non-homologous chromosomes do not share corresponding loci and do not align in tetrads. That makes this the correct \u201c<em>except<\/em>\u201d answer.<\/p>\n\n\n\n<p>The <strong>15:1 ratio<\/strong> in the rabbit cross suggests <strong>duplicate dominant epistasis<\/strong>. This means that either gene A or gene B can produce black fur. Only the double recessive genotype (<strong>aabb<\/strong>) lacks both dominant alleles, leading to the white fur phenotype. All other combinations (AaBB, AaBb, AAbb, etc.) produce black fur because at least one dominant allele is present. So, the only genotype that would result in a white rabbit is <strong>aabb<\/strong>.<\/p>\n\n\n\n<p>For the <strong>chi-square test<\/strong>, the critical value of 3.14 at a certain degree of freedom (often 1) is used as a threshold. If the calculated chi-square value (6.79) is <strong>greater<\/strong> than the critical value, this means the difference between observed and expected results is statistically significant. Therefore, the <strong>null hypothesis must be rejected<\/strong> because the deviation is too large to be due to chance. This suggests that some factor besides random variation is influencing the results.<\/p>\n\n\n\n<p>Each of these answers is based on fundamental genetic principles and standard statistical interpretation<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-131.jpeg\" alt=\"\" class=\"wp-image-30248\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-131.jpeg 1024w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-131-300x300.jpeg 300w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-131-150x150.jpeg 150w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner5-131-768x768.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>All of the following statements are true about meiosis, except: answer choices: During prophase I of meiosis, chromosomes pair tightly to form tetrads, the prophase I stage of meiosis can last several years in humans.
