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

. Consider the following scenarios. State whether the mutation is likely to be passed on to the offspring of the organism. Expla

Shalnov [3]

Answer:

The correct answer is "option a. it is likely it will pass to the offspring; option b. it is not very likely that it will pass to the offspring".

Explanation:

In order that a mutation could be passed to the offspring it is necessary that the affected DNA can be transmitted to the following generation. A single bacteria that contains a positive mutation in its DNA is likely to pass its mutation to the offspring since it multiples by binary fission. On the other hand, a skin cell most likely will not pass its mutation to the offspring since a skin cell is not involved in the organism reproduction, such as a sexual cell.
