Pure Breeding Parent Purple (I 1 I 1 ) and Starchy (TT)

Cross 1 F 1 of Purple x Purple 1) What are the parent genotypes? 2) What are the possible gametes from each parent? 3) Construct a 2 by 2 Punnett Square for the cross. 4) What are the F 1 genotype(s)?

Pure Breeding Parent Yellow (i 2 i 2 ) and Starchy (TT)

F 1 of Yellow x Yellow Another example of a “true-breeding” stock

Pure Breeding Parent Red (I 3 I 3 ) and Starchy (TT)

F 1 of Red x Red Another example of a “true-breeding” stock

Pure Breeding Parent Yellow (i 2 i 2 ) and Sweet (tt)

F 1 of Sweet x Sweet Another example of a “true-breeding” stock

Pure Breeding Parent White (i 4 i 4 ) and Starchy (TT)

F 1 of White x White Another example of a “true-breeding” stock

Cross 2 (Monohybrid) F 1 of Purple x Yellow 5) Which is the dominant: purple or yellow? 6) What must the parent genotypes for color be? 7) Construct a 1 by 1 Punnett Square for this cross. 8) What is the F 1 phenotype and genotype?

Cross 3 (Monohybrid) F 1 of Red x White 9) Which is the dominant: red or white? 10) What is the F 1 phenotype and genotype? 11) What must the parent genotypes for color be?

Cross 4 (Monohybrid) F 1 of Purple x Purple 12) What is the phenotypic ratio in the F 1 ? 13) What are the genotypes and phenotypes of the F 1 ? 14) What must the parent genotype and phenotype be? 15) Construct a 2 by 2 Punnett square for this cross. 16) Chi Square test of hypothesis and conclusion?

Cross 5 (Monohybrid) F 1 Offspring of Purple x Yellow 17) What is the phenotypic ratio in the F 1 ? 18) What must the parent genotypes and phenotypes be? 19) What is it called when you use a homozygous recessive to test an unknown genotype which is showing the dominant phenotype?

Cross 6 (Monohybrid) F 1 of Parent Red x White 20) What is the phenotypic ratio in the F 1 ? 21) What must the parent genotypes and phenotypes be?

Cross 7 (Monohybrid) F 2 from Parent Red x White 22) What is the phenotypic ratio in the F 2 ? 23) What must the original parent genotypes and phenotypes be to produce the F 1 that produced this F 2 ?

Cross 8 (Monohybrid) F 1 of Parent Starchy x Sweet 24) What is the phenotypic ratio in the F 1 ? 25) What must the parent genotypes and phenotypes be?

Cross 9 (Monohybrid) F 2 of Parent Starchy x Sweet 26) What is the phenotypic ratio in the F 2 ? 27) What must the original parent genotypes and phenotypes be?

Cross 10 (Dihybrid) F 1 of Purple Starchy x Purple Starchy 28) What is the F 1 phenotypic ratio? 29) What was the parent genotype and phenotype? 30) Question deleted. 31) Question deleted. 32) Chi Square test of hypothesis and conclusion?

Cross 11 (Dihybrid) F 1 of Purple Starchy x Yellow Sweet 33) What is the F 1 phenotypic ratio? 34) What was the parent genotype and phenotype? 35) Construct a 4 by 1 Punnett Square for this cross. 36) What is it called when you use a homozygous recessive to test an unknown genotype which is showing the dominant phenotype(s)? 37) Chi Square test and conclusion?
