En esta lección vamos a examinar algunos conceptos básicos relacionados con la herencia y los términos o vocabulario que van junto con esos conceptos.
A genetic unit of heredity; a specific section of DNA that codes for a specific protein.
Variation in a gene, an example would be eye color; there is a gene for eye color but there are different versions of genes that allow for different eye colors.
The term used to describe the specific location of a gene/DNA sequence on a chromosome; variations of these genes are referred to as alleles.
An organism with two identical alleles of a gene.
An organism with two different alleles of a gene.
A trait or characteristic expressed at the genetic level, that is, the genetic makeup of an organism.
An observable characteristic of someone’s traits, examples: eye color, skin color, height, gender etc.
When one allele masks the expression of another on the same locus, this is seen at the phenotype level.
An allele that is masked by a dominant allele, recessive alleles are only expressed when they are found in homozygous pairs.
The passing of traits from parents to offspring.
Dubbed the "father of modern genetics" and arguably modern biology, Mendel was an Austrian monk who studied heredity and inheritance in plants.
Receiving genetic characteristics from parents, the manner in which genes are passed down to offspring.
