Heredity
|
the passing on of physical or mental characteristics genetically from one generation to another
|
|
|
Inherited Trait
|
Heredity is the passing of traits to offspring (from its parent or ancestors). This is the process by which an offspring cell or organism acquires or becomes predisposed to the characteristics of its parent cell or organism.
|
|
|
Distinguish
|
recognize or treat (someone or something) as different
|
|
|
Identify
|
establish or indicate who or what (someone or something) is.
|
|
|
Characteristic
|
typical of a particular person, place, or thing
|
|
|
Polygenic Trait
|
are controlled by two or more than two genes (usually by many different genes) at different loci on different chromosomes. These genes are described as polygenes.
|
|
|
Environmental
|
relating to the natural world and the impact of human activity on its condition
|
|
|
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
|
|
|
Dominant
|
Genetics relating to or denoting heritable characteristics that are controlled by genes that are expressed in offspring even when inherited from only one parent.
|
|
|
Recessive
|
Genetics relating to or denoting heritable characteristics controlled by genes that are expressed in offspring only when inherited from both parents.
|
|
|
Co-Dominant
|
Genetics (of genes) having both alleles expressed equally in the phenotype of the organism
|
|
|
Punnett Square
|
A tool that helps to show all possible allelic combinations of gametes in a cross of parents with known genotypes in order to predict the probability of their offspring possessing certain sets of alleles.
|
|
|
Differentiate
|
recognize or ascertain what makes (someone or something) different
|
|
|
Genotype
|
the genetic constitution of an individual organism.
|
|
|
Phenotype
|
the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
|
|
|
Variation
|
a change or difference in condition, amount, or level, typically with certain limits
|
|
|
Mutation
|
the action or process of mutating : the mutation of ethnic politics into nationalist politics
|
|
|
Gamete
|
a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote
|
|
|
Somatic Cell
|
any of the cells of a plant or animal except the reproductive cells; a cell that does not participate in the production of gametes; "somatic cells are produced from preexisting cells";
|
|
|
Significance
|
the quality of being worthy of attention; importance
|
|
|
Occurrence
|
the fact or frequency of something happening
|
|
|
Recombination
|
Genetics the rearrangement of genetic material, esp. by crossing over in chromosomes or by the artificial joining of segments of DNA from different organisms.
|
|
|
Heterozygous
|
an individual having two different alleles of a particular gene or genes, and so giving rise to varying offspring.
|
|
|
Homozygous
|
an individual having two identical alleles of a particular gene or genes and so breeding true for the corresponding characteristic.
|
|
|
Incomplete Dominance
|
Dominance in genetics is a relationship between different forms (alleles) of a gene at a particular physical location (locus) on a chromosome.
|
|
|
Haploid
|
(of a cell or nucleus) having a single set of unpaired chromosomes.
|
|
|
Diploid
|
(of a cell or nucleus) containing two complete sets of chromosomes, one from each parent.
|
