Genetics
stating that when two alleles of an inherited pair is heterozygous, then, the allele that is expressed is dominant whereas the allele that is not expressed is recessive is. . .
Mendel's Law of Dominance
the science of heredity
Genetics
the process by which genetic information is passed on from parent to child. This is why members of the same family tend to have similar characteristics.
Inheritance
the record of descent of an animal, showing it to be purebred.
Pedigrees
the offspring of two plants or animals of different species or varieties
Hybrid
dominant if it is expressed in a person who has only one copy of that gene
Dominant Traits
consists of a square divided into four quadrants
Punnett Squares
A trait resulting from an allele that is independently and equally expressed along with the other
Co-dominant traits
a dominant trait or gene.
Dominant
bred from parents of the same breed or variety
Purebred
a trait that is expressed only when genotype is homozygous
Recessive Traits
one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
Allele
a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring
Genes
relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents
Recessive
having two different alleles of a particular gene or genes
Heterozygous
Law of Segregation
When an organism makes gametes, each gamete receives just one gene copy, which is selected randomly
Phenotypes
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Reproduction
the action or process of making a copy of something
Genotype
the genetic constitution of an individual organism.
Homozygous
having two identical alleles of a particular gene or genes
Law of Independent Assortment.
describes how different genes independently separate from one another when reproductive cells develop
Genotypes
the genetic constitution of an individual organism.
Environmental Factors
include temperature, food, pollutants, population density, sound, light, and parasites
Phenotype
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
