A monohybrid cross is a genetic mix between two individuals who have homozygous genotypes, or genotypes that have completely dominant or completely recessive alleles, which result in opposite phenotypesfor a certain genetic trait. Monohybrid crosses are used by geneticists to observe how the offspring of homozygous individuals express the heterozyg...
Gregor Mendel’s Peas
Although he did not know it at the time, Gregor Mendel used monohybrid crosses to identify dominant and recessive traits in his landmark experiments with peas. Gregor Mendel focused on several different genetic traits, but we will focus on one: stem length. Imagine that two types of pea plants grow in a garden. One type of pea plant has long stems, while the other has short stems. For the sake of this example, assume that both types of pea plant have a homozygous genotype (LL and ll), and tha...
Huntington’s Disease
Huntington’s Disease is a progressive degenerative condition that occurs in 4 to 15 of every 100,000 people in the United States. Having no cure, it is a certain death sentence for those diagnosed. While little is known about this condition, geneticists are sure that it is inherited via a dominant gene. At the simplest level, a monohybrid cross was used to determine the genetic nature of Huntington’s disease. Everyone carries the aptly-named Huntingtin gene, the gene responsible for the compl...
Confirming Dominant Traits
We have already discussed how scientists use monohybrid crosses to determine the dominant allele of a genotype. However, monohybrid crosses between homozygous individuals is often only the first step. Heterozygous crosses, in which both parents carry a dominant allele and a recessive allele, helps confirm whether a trait is dominant or recessive. The model for this second step greatly resembles the process Gregor Mendel followed, with peas. Using stem length as an example, scientists breed tw...
Genotype– The genetic code one inherits for a specific trait.Phenotype– The physical manifestation of a specific genetic trait that signals the inheritance of certain genetic codes.Homozygous– A genotype carrying two dominant or two recessive alleles. One allele is inherited from the father, and the other, from the mother.Heterozygous– A genotype carrying one dominant and one recessive allele.1. A monohybrid cross breeds one parent with a __________ ___________ genotype with another parent with a _________ __________ genotype to determine the ________ ______. A. Homozygous dominant, homozygous retrograde, dominant alley B. Heterozygous dominatrix, homozygous dominant, dominant allele C. Homozygous dominant, homozygous recessive, dominan...

Devolution events most often occur on the margins of state and at the heart of most devolutionary movements, however, is a strong sense of ethnocultural or economic difference---and when sense of difference coincide with conflicting senses of territory, the results can be explosive.
What are the differences between convergent and divergent evolution, and what are examples of each that support evolution by natural selection? What are examples of homologous and vestigial structures, and what evidence do these structures provide to support patterns of evolution? What are common misconceptions about the theory of evolution?
The AP ® Biology curriculum is organized around four major themes called the Big Ideas that apply to all levels of biological organization—from molecules and cells to populations and ecosystems. Each Big Idea identifies key concepts called Enduring Understandings, and Essential Knowledges, along with supporting examples.
