Answer:

A is false

Explanation:

Mutation is a change that occurs in the DNA nucleotide sequence either due to mistakes when DNA is copied during cell division or as a result of environmental factors e.g. UV radiation.

Since all the cells of an organism contains DNA, there are lots of places mutation can occur. However, some mutations are not passed from parents to offsprings and do not matter for evolution. This form of mutation is called Somatic or acquired mutation and it occurs in non-reproductive cells. Hence, won't be passed down from parents to offsprings. This form of mutation majorly occurs when DNA cells get replicated during mitosis or when the cell is exposed to harsh environmental factors that damages DNA strands e.g Ultraviolet radiation.

Mutations are only hereditary i.e can be passed down from parents to offsprings, if they occur in reproductive cells (sperms and eggs). This kind of mutation is called Germ-line mutation.

According to the question, mutations must not always occur in the parents before an offsprings DNA undergoes mutation.

Answer:

A

Explanation:

Parents do not need to have the mutation for their offspring to have it. Mutations can be present even without the parent having it.

The number of possible genetically different gametes for an organism equals
masya89 [10]

The organism can produce 12 genetically different gametes.

<h3><u>Explanation:</u></h3>

The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.

Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.

Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.

So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
