Question
11. A blue plant with large petals is selfed. The following progeny are recovered: o. recovere blue, large petals blue, small petals white, large petals white, small petals a) Are the genes for color and petal size: linked, unlinked, or cannot tell? Briefly explain why? b) Is the pattern due to independent assortment, crossing over, or cannot tell? Briefly explain why? c) If B-blue, b-white, P-large petals, p-small petals, if possible indicate the genotype of the two parental strains in the cross. d) If possible to determine, what is the map unit distance between B and P?Explanation / Answer
a- they are gene linked because recobinant are form blue with small petal and white with large petal
b-it is crossing over due to linked genes
c- posible genotype of two parental strain are blue large patern(p1) and white small patern(p2)
d- the map unit is one map unit is 1cm(centimorgan) and 1 cm represent the recombination frequency = (55+52)/(177+55+52+16) X 100= 55.4cM THE MAP DISTANCE IS 55.4 cM
