I have an urgent question as I have an exam tomorrow. I was skimming some past exam papers and one question came up which has me completely confused.
A cross was made between a pure breeding diploid pea plant with round, yellow seeds and a pure breeding diploid plant with wrinkled, green seeds. R and r for round and wrinkled respectively, and Y and y for yellow and green respectively. Assume dominant allele of each gene is upper case, and that the two genes are on different chromosomes and so are independently assorting.
a) Give genotypes of two pure breeding parents
b) Give the genotype of resultant F1 progeny
c) Give the genotype and respective frequency of the gametes produced by the F1 individual and indicate whether the gametes are parental or recombinant.
This is the question I am having trouble with and confused about
The reason I am confused is primarily I do not understand what is being asked when referring to the "gametes produced". Is this an F1xF1 cross and the question is asking about the F2 generation? I assumed not as the next question is:
Two of the F1 individuals obtained from the above parental cross were crossed to obtain the F2 generation
d) Give the phenotypes of the F2 progeny and their ratios
If someone could please shed some light on this it would be much appreciated
