How many genes do you share with your relatives?

September 15, 2020 By Maris Munkevics Leave a Comment Filed Under: Did You Know?, Genetics

A diagram of how many genes I share with my relatives.

It’s easy to calculate how many genes you share with your parents, children, siblings, and other relatives. Given the fact that parents pass half of their genes to their children, and siblings share half of their genes, the rest is just math. To determine this, you just have to divide genetic relatedness each time you […]

How do genes determine your traits?

genes determine eye color

Genes define who we are, at least in a physical sense, since they determine your traits. A tiny difference in DNA can specify whether you are a human of a chimp. But how does it work? How can genes, fragments of DNA determine traits? How can genes, for example, determine your eye color, height or even what flowers you like? Let’s find out.

Why humans and chimps look different if 99% of their genes are identical?

chimpanzees use tools like humans

Depending on who you ask, humans and chimps share 96 to 99 percent of genes. Yet we look staggeringly different. Or do we? Since genes alter our traits, we would expect organisms with so much of their genome identical, also look similar, right?

Chromosome fusion: Why humans have fewer chromosomes than chimps

chimpanzees are a lot like humans, but with more chromosomes

You may have heard that we humans have 23 chromosome pairs, whereas our closest neighbors chimpanzees have 24 — one pair more. Do we have to worry that humans have fewer chromosomes than chimps do? What is the function of those extra chromosomes that chimps need and we don’t? Let’s find out.
