Даун синдроми қандай пайдо бўлади? (видеода айтилмагани учун қўшимча: ёш ўтгани сари ҳужайралар бўлинишида хатоликлар кўпайиб боради, шунинг учун Даун синдроми эҳтимоли эам ошиб боради). #pediatrics#genetics

Даун синдроми белгилари: - ақли заифлик - калта бурун - ғилайлик - кўзни ички бурчагида қўшимча тери бурмаси - очиқ оғиз - ясси энса - қулоқ кичиклиги - иккига бўлувчи кафт чизиғи - бурмали тил - киндик чурраси - мушаклар тонуси сустлиги - туғма юрак нуқсони 🩺Doctor Ziyod | #genetics#pediatrics

🏋🏻‍♂️Спортчилар гени 🔤Болаликда баъзи синфдошларимиз жисмоний тарбияда заифроқлиги учун "лапашанг", "касой", "ланж" каби сўзлар билан камситардик, эсингиздами? 🙈 Бунда уларни айби йўқлигини генетика тушунтириб бера олади. ACTN3 генини «спортчилар гени» дейишади, у мушаклардаги альфа-актинин-3 оқсилини ишлаб чиқарилишига жавобгар. Бу генни уч ҳил варианти бор – R/R, R/X ва X/X. Шу "Х" қисми мутацияли бўлади ва етарлича альфа-актинин-3 ишлаб чиқара олмайди. "Х" ҳарфи бор инсонлар эса орамизда 43%ни ташкил қилар экан. Демак R/R ли инсонлар мушак кучига асосланган спорт турларида қобилиятлироқ бўлади. R/X лар ўртача, X/X эса спортда ютуқларга кўп ҳам умид қилмаса бўлади. ☝️Демак, қобилият ёки талант деганда генлар ҳам катта ролни ўйнайди. ❓Нима деб ўйлайсиз, болангиз жисмонан сустроқ бўлса ва жисмоний тарбияни ёқтирмаса, уни спортга бериб "ҳақиқий эркак" ёки "Барчинойдек" қилишга уруниш тўғримикан? 🩺Doctor Ziyod | #genetics#facts

🌎 The discovery of the structure of DNA in 1953 by James Watson and Francis Crick revealed that genetic information is stored as a double helix. Their breakthrough relied on Rosalind Franklin’s X-ray crystallography images, which showed the molecule’s repeating patterns. ✨ #genetics⚡#discovery⚡#biology 👉subscribe Interesting Planet 👉more Channels ​

The “Identical Ancestors Point” is estimated to be about 5,000–15,000 years ago. For Europeans, it may be around 1000 A.D. Some religions teach that all humans share common ancestors from a few thousand years ago, which is similar to these estimates. Simplified: Before this point, all living people share the same ancestors, but inherit different amounts of DNA. 🧬🌍 [Read more] #humanhistory#genetics#sciencefacts#ancestry#history@googlefactss

🗓January 13 marks the birth of Sydney Brenner (1927–2019) — an outstanding South African biologist 🇿🇦🧬 and one of the founders of modern molecular genetics. He made fundamental contributions to the decoding of the genetic code and to the study of developmental biology and cancer mechanisms. His pioneering research greatly advanced our understanding of genetics and molecular biology🔬✨ 🏅 In 2002, Sydney Brenner was awarded the Nobel Prize in Physiology or Medicine for discoveries that reshaped biological science. 📸 Photo: https://en.wikipedia.org/wiki/Sydney_Brenner #Science#Biology#Genetics#NobelPrize#SouthAfrica#SydneyBrenner

Haldane’s rule states that if one sex of a hybrid is absent, rare, or sterile, it is usually the heterogametic sex (e.g., XY in mammals). This pattern is common in hybrid animals and plants. [Read more1] [Read more2] [Read more3] @googlefactss #HaldanesRule#Genetics#Evolution#Biology#Science
