genetics
Asexual Reproduction- A type of reproduction when an offspring arise from a single organism. And only inherit genes from that parent only.
Advantage 2: The maturity is very rapid, and can happen in as few as 6 weeks.
disadvantage 1: The diversity is limited, because there is only one parent involved in reproduction.
Advantage 1: It occurs in many environments, because asexual organisms are highly adaptive and can adapt to many environments.
disadvantage 2: It can create competition, because asexual reproduction usually create offspring close to one another. Which creates a competition for resources.
Sexual Reproduction- A type of reproduction that combining genetic information from two individuals of different sexes.

Mutation- A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene.
Good mutations- Mutations can be beneficial, benign, or malignant, depending on where in the genetic code they are located. Examples of beneficial mutations include HIV resistance, lactose tolerance, and trichromatic vision.

Genotypes vs Phenotypes
Genotypes- An organisms genotype is the set of genes that it carries. And genotype is the genetic code.
Phenotype- An organisms phenotype is all of its observable characteristics. So phenotype is basically the physical trait, and it's the result of the Genotype.
Genome- Is 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- is a unit of DNA that is usually located on chromosomes, and it controls the development of one or more traits.
Proteins- Proteins are polymers of amino acids, they have a variety of function in cells.
Trait- a trait or character is a feature of an organism. The term phenotype is sometimes used as a synonym for trait in common use, but strictly speaking, does not indicate the trait, but the state of that trait
examples of natural selection- deer mouse, the peppered moth, and the peacock because they have all adapted to their environments.
Artificial Selection- is the intentional breeding of plants or animals. and means the same thing as selective breeding.
examples of artificial selection- fainting goats, farming livestock, and dogs.

Punnett square visual:
Punnett Square EXPLAINED: The punnett square is used to predict the genotypes of a particular cross or breeding experiment.
In the article "creatures without colours" it talks about albinism, and albinism is a rare genetic disorder. And can be passed down, and inherited.
