Answer:
1/128
Explanation:
In a diploid individual, 2ⁿ possible gametes can be produced, where <em>n</em> is the haploid chromosome number.
From those possible gametes,
- is the number of gametes that will contain maternal chromosomes only
- is the number of gametes that will contain paternal chromosomes only
- is the number of gametes that will contain a combination of both maternal and paternal chromosomes.
The probability that an individual spore will contain a set of chromosomes all of which came from the male gamete will be:

Answer:
order of least damaging is b, a, c and d
Explanation:
The 4 kinds of point mutations here present different consequences after a change of a single base pair. The silent point mutation is the least damaging because the alteration of the nucleotide does not implies on a different codon. Missense and nonsense point mutations will imply on a change of a entire different codon and a change of a entire codon to a stop codon, respectively. The missense could be a less aggressive mutation than a nonsense because the codon change may affect only in a small proportion of the entire protein, but the nonsense can be very aggressive by making the protein smaller than it is. The frameshift can cause severe modifications on the whole final protein because almost every codon might code for a different aminoacid leading to a whole new protein.

A gradient graph (derivative) representing the state of a dynamic equilibrium in a population should be a constantly straight (horizontal linear) line. Option 1 shows a increase which means it hasn't reached dynamic equilibrium. Option 2's average at all times is a constant number, which it fluctuates to maintain equilibrium. Option 3 shows a generally increasing trend, meaning the population is not balanced. Option 4 is plainly something that doesn't make sense as it is all over the place.
As the data points on Option 2 fluctuate around a certain value, it can be seen that Option 2 is the graph representing the state of a dynamic equilibium in the population.
