Genotype
The genotype of an organism refers to the genetic makeup of an individual. It consists of the complete set of genes inherited from its parents. These genes determine various traits and characteristics of the organism, such as eye color, height, and susceptibility to certain diseases.
Genotype Study Guide
- What is genotype?
Genotype refers to the genetic makeup of an organism, including all the genes inherited from its parents. - How is genotype different from phenotype?
While genotype refers to the genetic makeup, phenotype refers to the physical and observable traits of an organism that result from the interaction between its genotype and the environment. - What are alleles?
Alleles are different forms of a gene that can occupy the same position, or locus, on a chromosome. They can be dominant or recessive, and they determine the traits expressed in an organism. - What is a homozygous genotype?
A homozygous genotype occurs when an organism has two identical alleles for a particular gene, such as "AA" or "aa". - What is a heterozygous genotype?
A heterozygous genotype occurs when an organism has two different alleles for a particular gene, such as "Aa". - How do Punnett squares help in understanding genotypes?
Punnett squares are a visual representation used to predict the possible genotypes resulting from a genetic cross between two organisms. They help in understanding the probability of offspring inheriting specific genotypes.
Understanding genotypes is crucial in the study of genetics and inheritance, as it provides insights into how traits are passed from one generation to the next.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
