Genetics!

TermDefinition
DNA Genetic material in the nucleus of a cell, provides instructions for cell traits.
Gene A DNA section of a chromosome that codes for a trait.
Chromosome A collection of genes, made of DNA, that carries genes from parents to offspring.
Trait Any inheritable characteristic (physical or behavior).
Mutation A mistake made when a cell is copying DNA before mitosis, can result in a positive ,negative change in resulting cells or offspring.
Genetic Disorder A disease caused by a mutation in DNA.
Allele A version of a gene – there may be multiple versions in a population, such as alleles for hair color.
Genotype Genetic make-up of an organism, the particular combination of alleles.
Phenotype Physical make up of an organism, the actual physical features and behaviors.
Dominant Trait Trait that if the allele is present in the genotype, it will always be expressed in the offspring.
Recessive Trait Trait that is only expressed if two copies are present in the genotype.
Homozygous/Purebred Two copies of the same allele for a trait (TT or tt).
Heterozygous/Hybrid One dominant and one recessive allele for a trait (Tt).
Sexual Reproduction Reproduction where 2 parents each donate 50% of their genes to produce a genetically diverse offspring.
Asexual Reproduction Reproduction where 1 parent makes a genetically identical offspring with 100% the same genes. Ex: cloning, binary fission, budding.
Genetic Variation/Diversity The amount of different allele combinations present in a population of organisms. More diverse populations have more organism with different combinations of alleles.
