Mendel+Genetics+Vocabulary+(Unit+6,+Topic+1)


 * 1) __ Trait __ : any characteristic that can be passed from parent to offspring
 * 2) __ Heredity __ : passing of traits from parent to offspring
 * 3) __ Character __ : a heritable feature ( e.g. a flower color)
 * 4) __ Genetics: __ study of heredity
 * 5) __ Gregor Mendel: __ father of modern genetics
 * 6) __ Self ____ -pollination: __ pollen is transferred to the stigma of the same flower or a flower on the same plant
 * 7) __ Cross ____ - pollination: __ the transfer of pollen from an anther of a flower on one plant to the stigma of a flower on another plant of the same species
 * 8) __ Alleles __ : two forms of a gene ( dominant and recessive)
 * 9) __ Dominant __ : stronger of two genes expressed in the hybrid; represented by a capital letter
 * 10) __ Recessive __ : gene that shows up less often in a cross; represented by a lowercase letter
 * 11) __ Geno ____ type __ : gene combination for a trait
 * 12) __ Pheno ____ type __ : the physical feature resulting from a genotype (e.g. tall, short)
 * 13) __ Homo ____ zygous genotype: __ genotype combination involving two dominant or two recessive genes (e.g. RR or rr)
 * 14) __ Hetero ____ zygous genotype: __ gene combination of one dominant and one recessive (e.g. Rr); a.k.a. hybrid
 * 15) __ Mono hybrid cross__: cross involving a single trait
 * 16) __ Di ____ hybrid cross __ : cross involving two traits
 * 17) __ Punnett square __ : used to solve genetics problems
 * 18) __ Blending theory __ : offspring would have traits intermediate between those of it parents
 * 19) __ Particulate theory of Inheritance: __ shows that characteristics can be passed from generation to generation through discrete particles ( now known as genes)
 * 20) __ Law of Dominance: __ states that when different alleles for a characteristic are inherited( heterozygous), the trait of only one ( the dominant one) will be expressed
 * 21) __ Law of Segregation __ : law that states that alleles separate whenever gametes are formed
 * 22) __ Law of Independent Assortment __ : law that states that alleles for different traits are distributed to gametes independently
 * 23) __ P Generation __ : parental generation
 * 24) __ F1 Generation __ : first filial generation
 * 25) __ F2 generation __ : second filial generation
 * 26) __ Complete Dominance __ : the situation in which the phenotypes of the heterozygote and dominant homozygote are indistinguishable
 * 27) __ Incomplete Dominance __ : occurs in the heterozygous or hybrid genotype where the two alleles blend to give a different phenotype
 * 28) __ Codominance __ : the two alleles both affect the phenotype in separate, distinguishable ways
 * 29) __ True breeding __ : referring to plants that produce offspring of the same variety when they self-polinate.
