A trait that is not in your genes but is picked up from environmental factors
the different forms of a gene
cell structures that carry the genetic material that is copied and passed from generation to generation of cells made of DNA
an organism that is genetically identical to the organism from which it was produced
occurs when both alleles for a gene are expressed in a heterozygous offspring
deoxyribonucleic acid, the material that contains the information that determines inherited characteristics
describes a trait that covers over, or dominates, another form of that trait
all of the surrounding things, conditions, and influences affecting the growth or development of living things
the offspring of the P generation, first filial generation
the offspring of the F1 generation, second filial generation
parts of a chromosome that control inherited traits
The scientific study of heredity
genetic makeup of an organism
having two different alleles for a trait
having two identical alleles for a trait
an organism that has two different alleles for a trait, heterozygous
A picture of all the chromosomes in a cell arranged in pairs
The Father of Genetics
three or more forms of a gene that code for a single trait
Any change in the DNA sequence
The chemicals that make up the rungs of the DNA ladder. A-T and C-G match.
the failure of chromosomes to separate and segregate into daughter cells at division.
a diagram or family tree that shows the occurrence of a genetic trait in several generations of a family
The physical traits that appear in an individual as a result of its gentic make up, what an organism looks like
the movement of pollen from a stamen to a pistil of a flower
combined effect of two or more genes on a single characteristic such as eye color.
the mathematical chance that an event will occur
a chart that shows all the possible combinations of alleles that can result from a genetic cross.
offspring of many generations that have the same trait, homozygous
trait of an organism that can be masked by the dominant form of a trait
a characteristic that has a gene on the X-chromosome but no gene on the Y-chromosome
genetically determined characteristic
differences within a species, can be genetic or environmental
the passing of traits from parents to offspring
the combination of sperm from a pollen grain with an egg to form a seed
the process of selecting a few organisms with desired traits to serve as parents of the next generation.
