One limitation of a Punnett square as a model of inheritance is that it simplifies genetic interactions by assuming a single locus with two alleles, while many traits are influenced by multiple genes (polygenic inheritance) and environmental factors. Additionally, it does not account for phenomena such as incomplete dominance, codominance, or epistasis, which can complicate the expression of traits. Therefore, while useful for basic genetic predictions, Punnett squares may not accurately represent the complexity of inheritance patterns in real organisms.
The model used to show the pattern of traits passed from one generation to the next in a family is a pedigree chart. This chart displays the inheritance of traits and helps to track genetic patterns within a family over multiple generations.
The concept of a pedigree chart to display genetic information was not discovered by one individual, but rather developed over time through the work of various scientists and researchers in the field of genetics. Gregor Mendel's work on inheritance and genetics in the 19th century laid the foundation for the use of pedigree charts to track and analyze patterns of inheritance in families.
A dominant pedigree refers to a pattern of inheritance in which a dominant allele on a gene is expressed in the phenotype of an individual, masking the effects of a recessive allele. This results in the dominant trait being exhibited in individuals who inherit at least one copy of the dominant allele.
One limitation of a Punnett square is that it simplifies genetic inheritance by assuming that traits are determined by only one or two alleles, which does not account for more complex inheritance patterns such as polygenic traits, gene interactions, or environmental influences. Additionally, Punnett squares do not provide information about the actual likelihood of traits appearing in a population over time, as they focus on individual genetic crosses rather than population genetics.

A family record that shows inheritance could include details about assets, properties, and financial resources that are passed down from one generation to the next. It may outline who is entitled to specific items or wealth based on familial relationships and legal agreements such as wills or trusts. This record helps ensure a smooth transfer of inheritance while documenting the lineage of ownership within a family.
