1) To identify whether different described traits follow Mendelian or Non-Mendelian inheritance, we need to understand the basic principles of Mendelian genetics. According to Mendel's laws, traits are inherited as discrete units called genes, which are passed from parents to offspring in a predictable pattern. If a trait follows Mendelian inheritance, it means that the inheritance pattern of that trait can be explained by Mendel's laws, such as the law of segregation and the law of independent assortment.
On the other hand, Non-Mendelian inheritance refers to patterns of inheritance that do not follow Mendel's laws. These patterns involve more complex interactions between genes and may involve multiple genes, incomplete dominance, codominance, or other factors that affect the inheritance of a trait.
To determine whether a trait follows Mendelian or Non-Mendelian inheritance, we can look at the inheritance pattern of the trait in a family tree or pedigree. If the inheritance pattern of the trait can be explained by Mendel's laws, then it is likely to follow Mendelian inheritance. If the inheritance pattern cannot be explained by Mendel's laws, then it is likely to follow Non-Mendelian inheritance.
2) Non-Mendelian patterns violate Mendelian genetics because they involve more complex interactions between genes that cannot be explained by Mendel's laws. Mendel's laws assume that genes are inherited as discrete units and that each gene has a dominant and a recessive allele. However, in Non-Mendelian inheritance, genes may interact in more complex ways, such as through incomplete dominance, codominance, or epistasis.
For example, in incomplete dominance, the heterozygous offspring may have a phenotype that is intermediate between the two homozygous parents. In codominance, both alleles are expressed in the heterozygous offspring. In epistasis, one gene may mask the effect of another gene.
These Non-Mendelian patterns violate Mendel's laws because they involve interactions between genes that are more complex than what Mendel's laws can explain. Therefore, Non-Mendelian inheritance requires a more nuanced understanding of genetics and may involve additional factors, such as environmental influences or gene interactions, that can affect the inheritance of a trait.
