Basic Genetics Terms
The passing of characteristics from one generation to the next
The study of genetic material and how this material effect the characteristics of life forms. Also, the scientific study of heredity.
The branch of academic study devoted to systematic examination of basic concepts such as knowledge, truth, existence, reality, causality, and freedom. The study of knowledge.
Philosophy of Science
The branch of philosophy that sets the boundaries of science. Defines what is or not science.
Theory of gravity
Any two things with mass are attracted to each other
is the tendency of an object to remain station or continue in a straight line unless acted up on.
If we can imagine observations that we could make in the physical universe could disprove the idea.
Gene as nucleic acid segment, DNA or RNA that can ultimately direct the production of RNA that affects the phenotype It includes at least one region of nucleotides.
the location on the DNA where the code for a particular characteristic is found.
the single cell that results from the fusion of sperm and egg. (single cell embryo)
The particular sequence of nitrogenous bases found at a locus that codes for a particular characteristic.
The list of alleles found at the locus or loci under consideration.
The characteristics of the life form other than the genotype. It includes the morphological, physiological, biochemical, behavioral characteristic.
All the life forms in a population usually do not have the same phenotype
Principle of Allocation
No individual can collect an infinite number of resources. There are trade offs in organisms as it lives in different environmental types.
Norm of Reaction
Of a genotype is the total range of phenotypes produced by the genotypes in all possible environments
random effects in development (usually at the molecular level) that lead to variation in phenotypes
the vitamin essential for Drosophilia growth
The process that buffers the development of the organism
a plant with two cotyledons
first flowering plant ever sequenced
an autosomal recessive disorder characterized by the inability to break the amino acid phenylalanine.
a haploid fungus
an autosomal recessive disease characterized by the inability to break the sugar galactose
A rare human disease in which toxic substances accumulate in nerve cells. More frequent in Jewish sects in Eastern Europe.
A rare recessive disease in which thick mucus builds up in the lungs.
The prokaryotic ancestors of plastids and mitochondria probably gained entry into the host cell as undigested prey or internal parasites.
Goal of Genetic Analysis
A goal of genetic analysis is to identify all the genes that affect a specific phenotype and to understand their genetic, cellular, developmental, and molecular roles.
The locus affect more than one trait
When the heterozygote has the same phenotype as one of the two homozygotes
When the heterozygote has a phenotype that is immediate between two homozygotes
When each of the two alleles produces its full phenotype in the heterozygote
Refers to more than two alleles at a locus
