Biology is the physical science that studies life and living organisms, including their physical structure, chemical processes, molecular interactions, physiological mechanisms, development, and evolution. Biologists study the structure, function, growth, origin, evolution, and distribution of living organisms. Biology is an essential subject to study because it teaches students about the life cycle and what it entails. If you need to understand further about biology, try this quiz.

Incomplete dominance
Pleiotropy
Multiple alleles
Epistasis
The mother carries the gene but does not express it at all
The condition skipped a generation in the family
The child has a different allele of the gene than the parents
One of the parents has very mild expression of the gene
It is recessive
It is dominant
It has a late age of onset (> 60)
It is pleiotropic
A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents
A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny
A monohybrid cross results in a 9:3:3:1 ratio whereas a dihybrid cross gives a 3:1 ratio
A dihybrid cross involves organisms that are heterozygous for two characters and a monohybrid cross involves only one
No genes interacted to produce the parental phenotype.
Different genes interacted to produce the parental phenotype
One phenotype was completely dominant over another.
Each allele affected phenotypic expression
To observe whether or not a recessive trait would reappear
To observe whether or not the dominant trait would reappear
To distinguish which alleles were segregating
To be able to describe the frequency of recombination
