Glossary Flashcards
What does the term “genotype” refer to?
An organism’s genetic composition, describing all alleles
What does the term “phenotype” refer to?
The observable characteristics of an organism due to their genotype
What does the term “gene” refer to?
A section of DNA that contains coded information to form polypeptides and functional RNA
What does the term “allele” refer to?
A different form of a gene
What does the term “homologous chromosomes” refer to?
Homologous chromosomes are a pair of chromosomes that have the same gene loci and therefore the same features
What does the term “heterozygous” refer to?
The condition in which the alleles of a particular gene are different
What does the term “ homozygous dominant” refer to?
A genotype where an organism inherits two copies of a recessive gene
What does the term “heterozygous recessive” refer to?
A genotype where an organism inherits two copies of a recessive gene
What does the term “ diploid” refer to?
A term applied to cells in which the nucleus contains two sets of chromosomes
What does the term “co dominant” refer to?
The type of inheritance where two alleles of the same gene in an heterozygous organism are both expressed in the phenotype
How would you write a codominant allele?
Capital c and the allele in a to the power of type of style: C^(allele)
What does the term “ multiple alleles” refer to?
When a gene has more than two potential alleles
