Punnett Square
-
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment.
-
Natural Selection
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution.
-
Genome the haploid set of chromosomes in a gamete or microorganism, or in each cell of a multicellular organism.
Chromosomes a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
Genes a unit of heredity which is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
Proteins any of a class of nitrogenous organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, collagen
Traits a distinguishing quality or characteristic, typically one belonging to a person.
-
sexual reproduction when a new organism is created from two parents, sperm from the male and an egg from the female- sex cell combine to form a new organism - fertilization - then it gets 23 chromosomes from the Male and 23 chromosomes from the Female.
Asexual Reproduction ( ONE PARENT) offspring have identical DNA as a parent it is CLONED- offspring looks the same as the parent
There are several types: regeneration - planaria, budding - hydra, fission- cells of bacteria
Artificial Selection
he process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.
-
a sudden permanent change in the DNA, can be caused by the environment of a gene
-
Alleles - Different forms of the same gene - example (eyes) are the trait and Alleles is the color of the eyes or (Hair) alleles is it curly or straight
