In this case however, your red hair and your Rh-negative status are just a coincidence, not a case of genetic correlation.<br>So why do blonde hair and blue eyes but not red hair and Rh factor usually come together? Blonde hair and blue eyes are often found together in people because the genes for each trait are close together on the same chromosome.*<br>As you know, people have 2 copies of each chromosome &#8212; one from their mom and one from their dad. The chromosome you inherit from your mother is a combination of both of her copies of that chromosome, not just one of the original two she got from her parents. Nature has come up with this system to make everyone as different as possible.<br>How does this system work? When eggs and sperm are made, blocks of DNA are moved between the two chromosomes of a pair in a process called recombination. If two genes are on the same chromosome and very close to each other, they have a good chance of being moved together as a block and getting passed on to you as a single unit.<br>So where are the genes for red hair and Rh factor? The gene for red hair, MC1R, is found on chromosome 16. The gene for Rh factor is found on chromosome 1. Since the two genes are on different chromosomes, they can\u2019t be linked together. <\/p><cite>https:\/\/www.thetech.org\/ask-a-geneticist\/ask60<\/cite><\/blockquote>\n\n\n\n<p>I will give you a hint:<\/p>\n\n\n\n<p><strong>Are black people more likely to have curly hair?<\/strong><\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p> The scientists, from the Genetic Epidemiology Laboratory at the Queensland Institute of Medical Research (QIMR) in Brisbane identified the&nbsp;TCHH gene (trichohyalin)&nbsp;on <strong>chromosome one <\/strong>as the major gene controlling the <strong>curliness of hair<\/strong>. <br><br> <\/p><cite>https:\/\/medicalxpress.com\/news\/2009-11-gene-curly-hair.html<\/cite><\/blockquote>\n\n\n\n<p><a href=\"https:\/\/www.rhesusnegative.net\/staynegative\/rh-negatives-likely-wavy-hair\/\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\"Chromosome 1?
