Yei Flashcards
The characteristics of an organism
Trait
The study of heredity
Genetics
The passing on of traits from an organism to its offspring
Heredity
The basic unit of heredity
Gene
Stronger trait in genetics
Dominant
Weaker trait in genetics
Recessive
Organism with two different genes for a particular trait
Hybrid
Organism that has jeans that are alike for a particular trait
Purebred
Gene pairs that are not dominant or recessive. Neither gene in a gene pair masks the other
Incomplete dominance
Gene pairs separate during the sex cell formation
Law of segregation
Each gene pair for a trait is inherited independently of the gene pairs of all other traits
Law of independent assortment
The visible characteristics of an organism
Phenotype
The actual Gene makeup of an organism
Genotype
The possibility, or likelihood that a particular event takes place
Probability
Rod shaped structure that directs the activities of the cell and passes on the traits of a cell to new cells
Chromosome
Theory that states that jeans are found on chromosomes and that genes are carried from the parents or generation to the next generation on chromosomes
Chromosome theory
Deoxyribonucleic acid nucleic acid that serve the information needed to build proteins and carries genetic information about an organism
DNA
Each form of a gene
Allele
More than two alleles that combine to determine a certain characteristic
Multiple allele
Characteristics passed from parent to child on a sex chromosome
Sex Linked trait
The failure of chromosomes to separate from each other during cell division
Non-disjunction
The four nitrogen bases that make up a DNA molecule are adenine thymine guanine cytosine
Nitrogen bases
