Explain in detail how traits are passed from biological parents to offspring

Traits are passed from biological parents to offspring from heredity. Really, a Punnett Square. A Punnett Square lists all the Homozygous and Heterozygous alleles from each parent to figure out, what types of traits the offspring will have

 traits can be auto dominat or recessive. you receive alleles from each parent. A dominant trait needs only 1 allele to have expressed feature, a recessive trait you need both as in hemophilia or cystic fibrosis. A carrier has 1 affected alle, but the condition isnt expressed
