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 :
$(a) \;\& \;(b) only$
$(b) \;\& \;(c) only$
$(b) \;\& \;(d) only$
$(c) \;\& \;(d) only$
What is recombination ? Discuss the applications of recombination from the point of view of genetic engineering.
Definitions / Explanation : Linkage
Sexual reproduction leads to
Genetic map is one that
Two heterozygous parents are crossed. If the two loci are linked what would be the distribution of phenotypic features in $\mathrm{F}_{2}$ generation for a dihybrid cross?
