In corn, small pollen (sp) is recessive to normal pollen (sp+) and banded necrotic tissue, called zebra necrotic (zn), s ssive t

alex41 [277]

Answer:

Option B

Explanation:

Please see the attached image

Given -

Allele for small pollen is "sp"

Allele for normal pollen is "sp+"

and "sp+" is dominant over "sp"

Allele for zebra necrotic tissue is "zn"

Allele for normal necrotic tissue is "zn+"

and "zn+" is dominant over "zn"

Cross is carried out between

sp+ sp zn+ zn x sp+ sp zn+ zn

The gametes of the parent cells are -

sp+ zn+, sp+zn, spzn+, spzn

The cross would be as follows

sp+ zn+ sp+zn spzn+ spzn

sp+ zn+ sp+ sp+ zn+ zn+sp+ sp+ zn+ znsp+ sp zn+ zn+ sp+ spzn+ zn

sp+zn sp+ sp+ zn+ znsp+ sp+ zn znsp+ sp zn+ zn sp+ sp zn zn

spzn+ sp+ sp zn+ zn+sp+ sp zn+ znsp sp zn+ zn+ sp sp zn+ zn

spzn sp+ sp zn+ zn sp+ sp zn zn sp sp zn+ zn sp sp zn zn

Hence, option B is correct

Lina20 [59]

2) Krebs cycle is also called citric acidity cycle. In this cycle, hydrogen and electron are produced from the oxidation of pyruvate molecule and provides to electron transport chain.

3) Electrons carried by NADH + H and FADH2 are converted into oxygen through a series of electron carriers, and production of ATP occurs.
