Heredity Flashcards
The passing of genetic traits from a parent to a offspring.
Heredity
The passing of genetic traits from a parent to a offspring.
Dominant trait
A trait that reappears in the second generation after disappearing in the first generation when parents with different traits are bred.
Recessive Trait
One set of instructions for an inherited trait
Gene
One of the alternative forms of a gene that governs a characteristic, such as hair color.
Allele
An organism’s appearance or other detectable characteristic.
Phentotype
The entire genetic makeup of an organism; also the combination of genes for one or more specific traits.
Genotype
Chromosomes that have the same sequence of genes and the same structure.
Homologous Chromosomes
A process in cell division during which the number if chromosomes decreases to half the original number by two divisions of the necleus, which results in the production of sex cells.
Meiosis
One of the pair of chromosomes that determine the sex of the individual.
Sex Chromosoms
A diagram that shows the occurrence of a genetic trait in several generations of a family.
Pedigree
DeoxyriboNucleic Acid, a molecule that is present in all living cells and that contains the information that determines the traits that a living thing inherits and needs to live
DNA
In a nucleic-Acid chain, a subunit that consists of a sugar, a phosphate , and a nitrogenous.
Nucleotide
RibNucleic Acid, a moleucule that is present in all living cells and that plays a role in the protein production.
RNA
A change in the nucleotide-base sequence of the gene or DNA molecule.
Mutation
