Question
Answer
what term means analysis of inheritance patterns to identify and characterize genes?   genetics  
what term means biological factors that induce particular traits?   genes  
what term means alternate forms of a given gene, inherited from different parents?   alleles  
what term means an allele which always determines the phenotype?   dominant  
what term means an allele which only determines phenotype in the absence of a dominant allele?   recessive  
what term means an entity that carries a mutation? It can be an allele, or an individual.   mutant  
what term means the combination of alleles in an individual?   genotype  
what term means observable characteristics, i.e. the physical manifestation of the genotype?   phenotype  
what term means to carry both copies of the same allele, i.e. both dominant or recessive?   homozygous  
what term means to have different alleles, i.e. one dominant and one recessive?   heterozygous  
what term means a homozygous individual?   homozygote  
what term means a heterozygous individual?   heterozygote  
what term means a cross where one gene locus is tracked, e.g. Aa x Aa?   monohybrid cross  
what term means a cross where two loci are tracked, e.g. AaBb x AaBb?   dibybrid cross  
what term means a cross where three loci are tracked, e.g. AaBbCc x AaBbCc?   tribybrid cross  
what term means the first generation produced in a series of crosses?   filial one (F1)  
what term means the second generation produced in a series of crosses?   filial two (F2)  
what term means inheritance of alleles at one locus does not influence inheritance at other loci?   independent assortment  
what term means sex determining chromosome, X or Y?   sex chromosomes  
what term means any chromosome except X or Y?   autosome  
what term means a gene located on the X chromosome?   x-linked (sex linked)  
what term means any gene not located on X, or characteristic not associated with X?   autosomal  
in which gene abbreviation scheme is the recessive shown as a lower case letter, the dominant upper case?   scheme 1  
in which gene abbreviation scheme is the recessive shown as a lower case, italicized abbreviation (usually three letters), and the dominant with the same letters but with a + superscript?   scheme 2  
in which gene abbreviation scheme is the recessive shown in lower case italics, the dominant or wild type as a +?   scheme 3  
in a monohybrid cross, what is the ratio for the F2 genotype?   1:2:1  
in a monohybrid cross, what is the ratio for the F2 phenotype?   3:1  
in a dihybrid cross, what is the ratio for the F2 genotype?   1:2:1:2:4:2:1:2:1  
in a dihybrid cross, what is the ratio for the F2 phenotype?   9:3:3:1  
nheritance at one locus is dependent of another. is this true or false?   false  
why is there an equal number of F1 gametes in a dihybrid cross?   independent assortment  
in a dihybrid cross, how many possible combinations occur in the F2 progeny?   16  
what do the numbers 9:3:3:1 represent in the dihybrid F2 phenotype?   9 are dominant for trait 1 and trait 2; 3 are dominant for trait 1 and recessive for trait 2; 3 are recessive for trait 1 and dominant for trait 2; 1 is recessive for traits 1 and 2  
what purpose does a test cross serve?   it reveals recessive alleles by guaranteeing that they pair with other recessive alleles  
what is the ratio when crossing a homozygous recessive with a heterozygote?   1:1  
what is the genotype ratio in a test cross?   1:1  
what is the phenotype ratio in a test cross?   1:1  
what question does complementation answer?   if two mutants with the same phenotype are produced by mutations of the same gene, or by mutations of separate genes  
why are mutations in different genes complementary?   because the F1 are wild type heterozygotes  
why are mutations in the same genes non-complimentary?   because the F1 are homozygous mutant
