Monk who began the study of genetics.
Mendel
Chart showing inheritance of a trait over several generations.
Pedigree
A disorder that affects the mucous-producing glands, digestive enzymes, and sweat glands.
Cystic fibrosis
The first and longest phase of mitosis.
Prophase
The process of cytoplasm division.
Cytokinesis
Observable characteristics of an allele pair.
Phenotype
An individual who is heterozygous for a recessive disorder.
Carrier
Gangliosides accumulate in the brain, inflating brain nerve cells and causing mental deterioration.
Tay-Sachs disease
Mitotic phase where the chromatids pull apart.
Anaphase
Structure where sister chromatids are attached.
Centromere
An organism with two of the same alleles for a trait.
Homozygous
True/False:
Pedigrees can be used to examine both recessive and dominant genetic disorders.
True
Genetic disorder characterized by the inability of the body to digest milk and milk products.
Galactosemia
The second and shortest mitotic phase.
Metaphase
Spindle fibers, centrioles, and aster fibers form this.
Spindle apparatus
An organism with two different alleles for a particular trait.
Heterozygous
Daily Double
+2 on the next question.
Causes small body size and limbs that are comparatively short.
Achondroplasia
Mitotic phase when the chromosomes arrive at the cell poles and begin to decondense.
Telophase
Abbreviation for Parent Generation.
P generation
The allele that will be masked in a heterozygous pair.
Recessive gene
Affects the nervous system, causing gradual loss of brain function.
Huntington's disease
Individuals have very pale skin, white hair, and pink irises.
Albinism
Structures that contain identical copies of DNA.
Chromatin
An organism's allele pairs.
