Patterns of inheritance in humans are more complex than in peas or fruit flies due to factors such as environmental influences, genetic variability, and ethical constraints on controlled breeding experiments. Additionally, human generations take longer to observe compared to simpler organisms, making it more challenging to study inheritance patterns in humans.
Some common genetic inheritance patterns include autosomal dominant, autosomal recessive, X-linked dominant, and X-linked recessive. These patterns describe how traits are passed down from parents to offspring.
patterns of familial inheritance. patterns of sex-linked inheritance.
Autosomal dominant inheritance: a mutation in one copy of the gene is sufficient to cause the disorder. Offspring have a 50% chance of inheriting the mutated gene. Autosomal recessive inheritance: both copies of the gene must be mutated for the disorder to be expressed. Offspring have a 25% chance of inheriting the disorder. X-linked inheritance: the gene causing the disorder is located on the X chromosome. Males are more commonly affected as they only have one X chromosome.

Sex-linked traits in humans follow specific inheritance patterns based on the genes located on the sex chromosomes. In males, who have one X and one Y chromosome, sex-linked traits are typically passed down from the mother on the X chromosome. In females, who have two X chromosomes, the trait can be passed down from either parent. This results in different patterns of inheritance for males and females when it comes to sex-linked traits.
