Multiple alleles is when there are more than 2 alleles in a single trait. In blood type, instead of either one dominant and one recessive type alleles, there is one recessive allele (type O) but two dominant alleles(type A and B). Polygenic inheritance is when more than one gene controls a single trait, such as height in which three genes are responsible.

How are the word parts poly- and genic related to the meaning of the term polygenic traits?
The word part poly- means "many," and genic refers to genes. Polygenic traits are determined by multiple genes, each contributing a small effect to the overall trait. So, the terms poly- and genic in polygenic traits indicate that multiple genes are involved in determining the trait.
Why are most mutations in eukaryotes recessive?
Most mutations in eukaryotes are recessive because for a mutation to be expressed phenotypically, it typically needs to be present in a homozygous state. In a heterozygous individual, the presence of one normal allele usually masks the effects of the mutated allele, leading to a recessive trait.
How do modern taxonomists classify organisms?
Modern taxonomists classify organisms based on their evolutionary relationships using a combination of morphology, genetics, behavior, and biochemistry. They use a hierarchical system that groups organisms into categories such as domain, kingdom, phylum, class, order, family, genus, and species. This classification system helps to organize and categorize the vast diversity of life on Earth.
What is genic drift?
Genetic drift is change in allele frequencies due to random chance events. Two types are the Founder effect and the Bottleneck effect. The founder effect is when a subset of a population goes to a new are where there are no other of that same species. The bottleneck effect is when a large population is reduced to a small population. Genetic drift decreases variation in a population and has a greater effect on a smaller population than a larger one.
Why is the nucleus so important to the cell?
The nucleus is important to the cell because it houses the genetic material in the form of DNA, which contains instructions for cell function and growth. It also regulates gene expression and controls cellular activities through the production of messenger RNA. Additionally, the nucleus helps protect the DNA from damage by controlling its access and interactions with other cellular components.

Having the left thumb cross over the right thumb is neither related to a recessive nor dominant gene. It is more of a behavior as to which thumb feels more natural on top when fingers are crossed.
