Chromosomes are super important for our genes. They carry the information that makes us who we are. Humans have 46 chromosomes, which we group into 23 pairs. Out of these, 22 pairs are called autosomes, and the last pair tells us whether we're male or female. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY).
Our traits come from genes located on these chromosomes. Each gene can have different forms, which we call alleles. Here are some key ideas about inheritance:
Pedigree charts are useful tools that show family relationships. They help us understand how certain traits or disorders are passed from one generation to another. For example, an autosomal recessive disorder like cystic fibrosis happens in about 1 in 2,500 births in Caucasian people.
About 1 in 150 babies are born with a genetic disorder. Some common ones include:
By learning about chromosomes and how they work, we can better understand the variety of genes in humans and how traits are inherited.
