Ever wondered why you have your father\u2019s height but your mother\u2019s eye color? Or why\u00a0two tall pea plants can\u00a0sometimes produce a short one? The answer lies in the\u00a0<\/span>Monohybrid Cross<\/span><\/b>\u2014the foundation of modern genetics.<\/span>\u00a0<\/span><\/p>\n

If you are a Class 10 student preparing for your CBSE, ICSE, or State Board exams, this is one of the most important topics in the “Heredity” chapter. In this guide,\u00a0we\u2019ll\u00a0break down the concepts, ratios, and diagrams into simple, bite-sized pieces that will help you score full marks.<\/span>\u00a0<\/span><\/p>\n

What is a Monohybrid Cross? (Simple Definition)<\/span><\/b>\u00a0<\/span><\/h1>\n

A\u00a0<\/span>monohybrid cross<\/span><\/b><\/a>\u00a0is a genetic experiment that focuses on the inheritance of\u00a0<\/span>one single trait<\/span><\/b>\u00a0at a time. For example, if we only look at the height of a plant (Tall vs. Dwarf) while ignoring its seed color or shape, we are performing a monohybrid cross.<\/span>\u00a0<\/span><\/p>\n

Gregor Mendel, the “Father of Genetics,” used garden pea plants (<\/span>Pisum sativum<\/span><\/i>) to show how traits are passed from parents to offspring through these crosses.<\/span>\u00a0<\/span><\/p>\n

Key Term:<\/span><\/b>\u00a0A “Monohybrid” is an offspring produced by parents that differ in only one trait.<\/span>\u00a0<\/span><\/p>\n

The Step-by-Step Process of a Monohybrid Cross<\/span><\/b>\u00a0<\/span><\/h5>\n

Mendel\u2019s classic experiment involved crossing a pure-bred\u00a0Tall\u00a0plant with a pure-bred Dwarf plant. Here is how it works:<\/span>\u00a0<\/span><\/p>\n
