Biology

in flour beetles, pygmy (py) is recessive to normal size (py+)and red color (r) is recessive to brown (r+). A beetle heterozygousfor these characteristics was testcrossed to a red pygmy beetle.The table below shows the numbers and phenotypes from the progenyof this testcross - use this information to answer the followingthree questions. Progeny phenotype Progeny number

Normal size, brown 180

Normal size, red 20

Pygmy, brown 10

Pygmy, red 190

Total 400 Flag this Question

Question 21. What is the recombination frequency between py andr? Please express your answer as number (no words), in units ofcentimorgans.

Question 22. If these two genes were completely unlinked, howmany progeny (out of 400) would we expect in each phenotypic classin the table above? Express your answer as a number (nowords).?
