Diagram a cross between a true breeding pea plant that produces yellow seeds (G/G) with one that produces green seeds (g/g). Carry the cross out to the F2 generation. Answer the following questions:
What was the F1 genotype and phenotype?
What kinds of gametes could the F1 individuals produce?
What were the F2 genotypes and phenotypes, and in what ratios would you expect each to occur?
Diagram a cross between a true breeding pea plant that produces round seeds and purple flowers, with one that produces wrinkled seeds and white flowers. (Round and purple are the dominant traits.) Carry the cross out to the F2 generation. Answer the following questions:
What are the P1 genotypes?
What is the F1 genotype and phenotype?
What kinds of gametes will the F1 individuals produce?
What are the F2 genotypes and phenotypes?
What genotypic and phenotypic ratios are expected in the F2 progeny?
Diagram a cross between a true breeding pea plant that produces yellow seeds (G/G) and purple flowers (W/W) with one that produces green seeds (g/g) and white flowers (w/w). Carry the cross out to the F2 generation. Answer the following questions:
What was the F1 genotype and phenotype?
What kinds of gametes could the F1 individuals produce?
What were the F2 genotypes and phenotypes, and in what ratios would you expect each to occur?
Diagram a test cross of the F1 individuals from the question above, with the homozygous recessive parent strain. What genotypes and phenotypes would you expect in the testcross progeny, and in what ratios?
If you had a fruitfly with phenotype A, what test would you make to determine if it was Aa or AA? Explain the different outcomes expected if the fly in question is AA or Aa.
If individuals of genotype AaBbCc are intercrossed:
How many different genotypes can occur in their progeny? How many different phenotypes can occur in the progeny?
