Genotype
The amount of blood tested
How many sickle cells
Recessive Allele
Phenotype
Open system
Heredity
Amount of oxygen received by cells
Trait
Pollination
A plant that produces offspring with the same form of a trait when self pollinated
An Austrian monk who studied pea plants that was known as the "Father of Genetics"
Pollen grains containing sperm from the male part of the plant (anther) are carried to the female part of the plant called the ovule (self and cross pollination).
How does the number of sickle cells in a human body effect the amount of oxygen that is received by cells. dependent variable?
A characteristic that an organism can pass on to its offspring.
The set of traits an organism receives from its parents
How does the number of sickle cells in a human body effect the amount of oxygen that gets to cells. Independent variable.
When matter cannot enter or leave a system.
The form of a trait that is displayed in an organism (what you see).
A segment or unit of DNA that determines traits (heredity)
Different forms of the same trait (gene)
How does the number of sickle cells in a human body effect the amount of oxygen that gets to cells. Controlled variable.
A weaker form of a gene that is hidden when combined with a dominant allele. (lower case)
When matter or energy moves inside of a system
When matter can enter and leave a system.
A stronger form of a gene that, when present, covers up the appearance of the recessive allele. (capital letter)
Something made of two or more parts working together to perform a function
An organisms genotype shows the actual alleles of the gene.
