33
Heterozygous/heterozygote
Zygous: Pair of genes where one is recessive, and one is dominant. Zygote: An individual having two different alleles of a particular gene or genes.
34
Homozygous/homozygote
Zygous: Pair of matching alleles Zygote: An individual having two identical alleles of a particular gene or genes.
35
Meiosis
Type of cell division that results in four daughter cells each w/ half the number of chromosomes of the parent cell.
36
Mitosis
Type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.
37
Haploid
Deriving from cell or nucleus--having a single set of unpaired chromosomes.
38
Diploid
Deriving from cell or nucleus--containing two complete sets of chromosomes, one from each parent.
39
Blending theory
The discredited theory that inheritance of traits from two parents produces offspring w/ characteristics that are intermediate between those of the parents.
40
Independent assortment
Formation of random combinations of chromosomes in meiosis and of genes on different pairs of homologous chromosomes by the passage.
41
Particulate inheritance
(Pattern of Inheritance) Showing that phenotypic traits can be passed from generation from generation though 'discrete particles' known as genes.
42
Law of segregation
During the production of gametes the two copies of each hereditary factor segregate so that offspring acquire one factor from each parent.
43
Tay Sachs Disease
Inherited disorder that destroys nerve cells in the brain and spinal cord
44
Chromosome
Threadlike structure of nucleic acids and protein found in the nucleus of most living cells.
45
Gene
Unit of hereditary that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
46
Allele
One of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
47
Hemizygous
Having or characterized by one or more genes that have no allelic counterparts.
48
Sickle cell anemia
Severe hereditary form of anemia in which a mutated form of hemoglobin distorts the red blood cells into a crescent shape at low oxygen levels.
49
Sickle cell allele
When a person has an abnormal allele of the hemoglobin beta gene (is heterozygous), but does not display the severe symptoms of sickle cell disease.
50

Type A Type B Type O Type AB
51

Individual who inherits blood type O, who can donate blood to any recipient of blood type ABO
52
Universal recipient
Individual who inherits blood type AB, who can in theory receive donated blood from blood groups ABO.

Carries a portion of the DNA code to other parts of the cell for processing.
70
tRNA
Helps decode the messenger RNA sequence into a protein.
71

When the blood to clot is severely reduced, causing the individual to bleed severely.

75
Point mutation
Mutation affecting only one or very few nucleotides in gene sequence.
76
Chromosomial mutation
