Question

2. We have F = freckles, f = no freckles, curly hair = C and c= straight hair. If FFCC marries with ffcc mention the P, F1 and F2 generations with the Punnett squares and showing the fractions and percentages for phenotypes and genotypes.

Answer 1

Hi Shifa,

Because you are crossing a completely dominant with a completely recessive, the F1 generation would all be hybrids. FFCC X ffcc = 100% FfCc. Then, to find the F2 generation you will cross the F1 generation with itself. FfCc x FfCc

I filled out the first row for you here. Once you fill out the table, highlight the different genotypes first. The denominator here is 16. As you know, dominant (FF) and hybrids (Ff) will show the dominant phenotype.

I hope this is helpful! Please let me know if you'd like more detail on how to finish this problem.

Best,

Amy
