4.Principles of Inheritance and Variation
medium
Morgan hybridised yellow-bodied, white-eyed females to brown-bodied, red-eyed males and intercrossed their $F_{1}$ progeny. He observed that
$(a)$ $F_{2}$ ratio was deviated very significantly from the $9 : 3 : 3 : 1$ ratio
$(b)$ Both genes did not segregate independently of each other
$(c)$ Recombinant types are not obtained in $F_{2}$ generation
$(d)$ Both genes segregate independently of each other
Select the correct set of statements :
A
$(a) \;\& \;(b) only$
B
$(b) \;\& \;(c) only$
C
$(b) \;\& \;(d) only$
D
$(c) \;\& \;(d) only$
Solution
Brown body and red eye are linked gene so $F_{2}$ ratio deviated from $9 : 3 : 3 : 1$
