Science

Breed

A set of animals that in some way are diffrent from others in the same species

Breeding

To mate 2 organisms of the same speicies to produce offspring

Cross breeding

When diffrent varieties or breeds are mated with one another

Selective breeding

When humans choose certain animals and plants that have useful charateristics and breed more of those organisms

Yield

How much of something useful to humans that an organism produce

Allele

specific variant form of a gene

Homozygous

When you inherit the same allele from both your parents

Hetreozygous

one allele inherited from each biological parent.

Genotype

complete set of genetic material an individual carries for a trait or gene

Phenotype

observable physical chareteristics of a human being

Dominant

version of a gene which overpowers a reccessive gene

recessive

allele whose traits are masked by the dominant allele

punnet square

grid used in biology to predict a offspring inheriting traits from their parents

When do you use a bar or histogram

bar when the date is discontinuous eg. right handed left handed and histogram when the data is continous eg. weight

Natural selection

describes how organisms better adapted to their environment are more likely to survive, reproduce, and pass on their advantageous genetic traits.
