Heredity And Reproduction Flashcards
(26 cards)
Trait
A physical characteristic that an organism possesses
Cross- pollinate
To transfer the pollen from one plant to the reproductive structure of another plant
Allele
A member of a gene pair
Dominant trait
A trait that is most likely to appear in offspring
Gene
The part of DNA that gives instructions for what traits offspring will have
Genotype
The combination of genes passed on to offspring
Phenotype
The way an organism looks based on its genotype
Probability
The mathematical chance that something will happen
Recessive trait
A trait that is least likely to appear in offspring
Budding
When a new organism grows from the body of an existing organism
Chromatid
One half of a copied chromosome
Egg cell
A female sex cell
Homologous pair
A pair of matching chromosomes
Meiosis
Cell division that produces sex cells
Sex cell
A parent cell that combines with another sex cell during sexual reproduction to form a new organism
Sperm cell
A male sex cell

Taxonomy
The classification of organisms
Species
All the organisms of the same type that can reproduce young of the same kind
