Marfan syndrome, a dominant single gene defect is characterised by lens dislocation, long limbs, spindly fingers, caved in chest and weakened aorta. This is an example of
Complete dominance
Epistasis
Pleiotropy
Codominance
Pyramid of biomass is more real than the pyramid of number; because
The former take the size of individuals into consideration, but the later does not
Number of individuals are easier to count than calculating biomass
Less number of parameters are considered in the former, but the later accounts the whole existing conditions
The former may be inverted in some cases, but the later is always upright
The replacement of a normal gene by its specifically mutated copy is
Gene cloning
Gynogenesis
Gene knockout
lnterparietal hybridisation
The phase involved in the process of spermateliosis is
Multiplication phase
Growth phase
Maturation phase
Differentiation phase
