Inheritance of sex-linked traits differs between boys and girls because boys have one X and one Y chromosome, while girls have two X chromosomes. This means that boys inherit sex-linked traits from their mothers, while girls can inherit them from both parents.
One key difference is that autosomal traits are located on the autosomes (non-sex chromosomes), while sex-linked traits are located on the sex chromosomes (X or Y). This difference affects how these traits are inherited and expressed, as sex-linked traits show different inheritance patterns among males and females.
Sex-linked inheritance refers to the inheritance of traits that are carried on the sex chromosomes (X and Y). Maternal inheritance, on the other hand, refers to the inheritance of traits that are passed down exclusively from the mother through the mitochondrial DNA. Sex-linked traits can be passed down by both males and females, while maternal inheritance is specific to traits passed from the mother.
Mendelian inheritance patterns follow predictable rules of inheritance, such as dominant and recessive traits, as described by Gregor Mendel. Non-Mendelian inheritance patterns involve more complex genetic interactions, like incomplete dominance or codominance, that do not strictly follow Mendel's laws.
Mendelian traits follow predictable patterns of inheritance based on the principles discovered by Gregor Mendel, such as dominant and recessive alleles. Non-Mendelian traits do not follow these patterns and may be influenced by multiple genes or environmental factors.
Pleiotropy refers to a single gene influencing multiple phenotypic traits, while polygenic inheritance involves multiple genes contributing to a single trait. Pleiotropy can lead to diverse phenotypic effects, while polygenic traits are often influenced by the additive effects of multiple genes.

Polygenic inheritance includes traits coming from one source. Mendel described traits as dominant or recessive and that determination created the charts determining the offspring outcome.

Sex-limited inheritance affects the transmission of genetic traits by causing certain traits to be expressed only in one sex. This can lead to differences in the prevalence of certain traits between males and females within a population, impacting the overall genetic diversity and distribution of traits.

Gregor Mendel was a biologist who studied the inheritance of traits. His laws for this inheritance are combined in Mendelian inheritance, which states that some alleles are dominant and as such some traits are dominant.
Mendelian genetics follow predictable inheritance patterns based on dominant and recessive traits, while non-Mendelian genetics involve more complex inheritance patterns such as incomplete dominance, codominance, and polygenic traits. Mendelian traits are controlled by a single gene, while non-Mendelian traits may involve multiple genes or environmental factors.
Alleles are different forms of a gene that can be inherited from each parent, while genotype refers to the specific combination of alleles an individual has for a particular gene. In genetic inheritance, alleles determine the genotype of an individual, which in turn influences their traits and characteristics.
Traits that exhibit non-Mendelian inheritance patterns include traits controlled by multiple genes, traits influenced by environmental factors, traits with incomplete dominance, traits with codominance, and traits linked to the sex chromosomes.
