What are genes, and how many do humans approximately have?
What are genes, and how many do humans approximately have?
Genes are sections of DNA that code for a specific trait, and humans have approximately 1000s of genes.
What is the relationship between a gene and a trait, and how is it often oversimplified?
What is the relationship between a gene and a trait, and how is it often oversimplified?
A gene codes for a specific trait, but it's not always a one-to-one relationship; however, it's often oversimplified in basic biology classes as one gene for one trait.
What are alleles, and how can they be thought of in terms of genes?
What are alleles, and how can they be thought of in terms of genes?
Alleles are different forms of the same gene, and can be thought of as different flavors or varieties of the gene.
