What is heredity?

• passing of genetic information from one generation to the next

• type of reproduction that forms new organisms with one single parent

• type of reproduction that forms new organism from two parent

• learning about your history

A disadvantage of sexual reproduction?

• There is genetic variation diversity of population

• Organisms can adapt to environment

• Population growth is slow because two parents are required to make offspring

• Mutation can occur easily

Mitosis takes place in

• Asexual Reproduction

• Sexual Reproduction

What happens during meiosis?

• Two daughters cells contain half of the genetic information from parent cell

• One daughter cell and one son cell contain half of the genetic information from the parent cell

• Four daughters cells contain half of the genetic information from the parent cells

• Four sons contain half of the genetic information from the parent cell.

Phenotype is

• an organism genetic makeup

• an organism physical characteristic that can be observed

• an organism DNA

A dominant allele is expressed in phenotype with

• AA

• aa

• Aa

A recessive allele is in the phenotype when two copies are present

• AA

• Aa

• aa

Alleles that have the same form of the same gene is called

• Homozygous

• Heterozygous

• Genotypes

• Phenotypes

Alleles that have two different forms of the same gene are called

• Homozygous

• Heterzygous

• Genotypes

• Phenotypes
