AP Biology Mendel Genetics Flashcards

5703033349	Character	A heritable feature that varies among individuals	0
5703033350	Trait	Each variant for a character	1
5703033351	True-breeding	Over many generations, it had produced only the same variety as the parent	2
5703033353	Allele	Alternative versions of a gene	3
5703033354	Dominant Allele	Determine the organisms appearance-Capital letter	4
5703033355	Recessive allele	No noticeable effect of the organisms appearance-aa	5
5703033356	Law of Segregation	States that the two alleles for a heritable character separate from each other during gamete formation and end up in different gametes	6
5703033357	Homozygous	Pair of identical alleles for a character	7
5703033358	Heterozygous	Two different alleles for a gene	8
5703033359	Phenotype	An organisms appearance or observable traits	9
5703033360	Genotype	An organisms genetic makeup	10
5703033361	Testcross	Breeding an organism of unknown genotype with a recessive homozygote	11
5703033363	Monohybrid Cross	Cross of two heterozygotes(Rr)	12
5703033364	Dihybrid	Individuals heterozygous for the two characters being followed in the cross(YyRr)	13
5703033365	Law of Independent Assortment	States that each pair of alleles segregates independently of each other pair of alleles during gamete formation	14
5703033368	Complete dominance	The offspring always looked like one of the two parental variety because one allele in the pair showed __________	15
5703033369	Incomplete dominance	Three or more potential varieties from crossing tow parents	16
5703033370	Co-dominance	Two alleles each affect the phenotype in separate, distinguishable ways	17
5703033372	Epistasis	the phenotypic expression of a gene a one locus alters that of a gene at a second locus	18
5703033373	Polygenic Inheritance	An additive effect of two or more genes on a single phenotypic character	19
5703033374	Carrier	Heterozygous person can transmit the recessive allele to their offspring without themselves having the trait	20
