A cross between pure tall Pea plant with green pods and dwarf Pea Plant with yellow pods will produce short `F_(2)` plant out of 16
A. 9
B. 3
C. 4
D. 1
Correct Answer - C
This is an example of dihybrid cross because two characters are being studied simultaneously in which dwarfness is a recessive characters, so in `F_(2)`-generation 4 plants will be dwarf out of 16.
(i) `P_(4) ("yellow")+5O_(2)(g) rarr P_(4)O_(10)+9.19 kJ`
(ii) `P_(4) ("red")+5O_(2)(g) rarr P_(4)O_(10)+8.78 kJ`
Subtracting, `P_(4) ("yellow")-P_(4) ("red")=1.13 KJ`
`rArr P ("yellow")=P_(4) ("rad")+1.13 KJ`
So, heat of transition of yellow to red...
Correct Answer - 104.1 mm Hg

Correct Answer - 4
The number pf photon is `N=E/(hv)=(PDeltat)/(h(c//lambda))=(lambdaPDeltat)/(hc)`
Substitution of the data gives
`N=((5.60xx10^(-7)m)xx(100Js^(-1))xx(1.0s))/((6.626xx10^(-36)s)xx(3xx10^(8)ms^(-1)))=2.8xx10^(20)`
The appearance of the recessive trait in F1 generation (dwarfism) confirms the presence of one recessive allele in the dominant parent and makes it heterozygous for plant height (Tt). Since...
