The correct choice from the options provided is <strong>tetrad<\/strong>.<\/p>\n\n\n\n<p>During meiosis, specifically in <strong>prophase I<\/strong>, homologous chromosomes pair up closely in a process called <strong>synapsis<\/strong>. This pairing results in a <strong>tetrad<\/strong>, which consists of <strong>four chromatids<\/strong>\u2014two from each of the homologous chromosomes. These chromatids are later involved in <strong>crossing over<\/strong>, a genetic process that allows the exchange of genetic material and increases genetic diversity in offspring.<\/p>\n\n\n\n<p>To understand why <strong>tetrad<\/strong> is the right answer, it helps to look at the incorrect choices:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Chromatid<\/strong> refers to one of the two identical halves of a duplicated chromosome. A chromatid is not a pair; it is a single strand that becomes visible during cell division.<\/li>\n\n\n\n<li><strong>Zygote<\/strong> is a single cell formed when a sperm fertilizes an egg. It contains a full set of chromosomes, but it is not a pair of homologous chromosomes.<\/li>\n\n\n\n<li><strong>Gamete<\/strong> is a reproductive cell (sperm or egg) that contains only one set of chromosomes (haploid). Gametes are produced through meiosis, and they do not have pairs of homologous chromosomes.<\/li>\n<\/ul>\n\n\n\n<p>In contrast, a <strong>tetrad<\/strong> is the structure that includes <strong>both homologous chromosomes<\/strong> lined up together, and each chromosome is made of two chromatids. This configuration is essential for genetic recombination and the correct segregation of chromosomes during meiosis.<\/p>\n\n\n\n<p>Therefore, a <strong>tetrad<\/strong> directly represents a homologous chromosome pair and is the best answer based on the biological process of meiosis.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-761.jpeg\" alt=\"\" class=\"wp-image-36146\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-761.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-761-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-761-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Which is a homologous chromosome pair? chromatid zygote gamete tetrad The Correct Answer and Explanation is: Correct Answer: Tetrad A homologous chromosome pair refers to two chromosomes\u2014one from each parent\u2014that are similar in shape, size, and genetic content.
