What is Heredity?
The passing of physical characteristics from parent to offspring
Heredity
Dominant
The physical appearance of a trait (the visible piece)
phenotype
Traits are controlled by alleles; they are passed from parent to....
offspring
The scientific study of heredity
Genetics
This is the type of trait that, when a dominant allele is present, remains hidden
Recessive
The genetic makeup of an organism
genotype
What does it mean if a trait has been hidden?
This means that the recessive trait is hidden by a dominant trait - it can appear in later generations
A specific characteristic; such as stem height or color of seed is called a
This is a chart that shows all of the possible ways to combine alleles in a genetic cross
Punnett Square
An organism that has two identical traits
(Ex: BB or bb)
homozygous
What did the "Father of Genetics" look at to start studying genetics
Pea plants and flowers
This describes a factor that controls the traits
Gene
What is an example of an inherited trait?
body / skin color, height, freckles, eye color
An organism that has two different alleles for a trait
(Ex: Bb)
heterozygous
He is known as the "Father of Genetics"
Gregor Mendel
The different forms of genes (ex: BB, Bb, bb)
What is an example of an acquired trait?
dyed hair colors, pierced ears
This occurs when one allele is only partially dominant
(Ex: a red flower and a white flower make a pink flower)
incomplete dominance
Describe what traits "Father of Genetics" studied
Height of pea plants and color of seeds
