Inheritance and Genetic Variation
Stemscopedia Text
How can siblings look so different if they share the same parents?
What Do You Think?
Reproduction: a process by which organisms produce offspring
There is sexual reproduction and asexual reproduction
Reflect #1
Genetic Variation: a difference in inherited characteristics between parents and offspring
Inherited Trait: a characteristic that is passed from parent to offspring
Siblings are not identical, even if they look alike
Reflect #2
There are different forms of asexual reproduction: binary fission, spores, budding
Prokaryotic organism: a simple, one-celled organism that lacks a nucleus and other membrane-bound organelles; typical of bacteria cells
Eukaryotic Organism- a cell with a nucleus and membrane-bound organelles; typical of plant and animal cells
Sexual reproduction creates an offspring by the fertization of an egg by a single sperm
What Do You Think?
Dominant allele: if dominant is present and represented by a capital letter
Recessive allele may be covered up and represented by a lowercase letter
Look Out
Allele: variation of a specific gene
Genotype: the pair of alleles an organism inherits for each gene
Phenotype: the final outward appearance
Look Out!
Punnett Square
Punnet squares show the probability of the occurrence of a certain trait.
For recessive to be shown, both parents must have a recessive

Pedigrees are a different way to predict traits
