hodyreva [135]

Answer:

Sperm undergo more mitotic cellular divisions than egg and therefore have a higher risk of developing a spontaneous mutation.  

Explanation:

As you have seen in the question above, lycanthropy is a mutation that is more likely to be established as the supply of male gametes comes from older men. This is because sperm undergo more mitotic cell divisions than eggs, and therefore are at greater risk of developing a spontaneous mutation.

In order for you to understand this, you need to know that eggs (which are female gametes) are produced at once in a woman's body. Thus, cell division is limited and therefore the opportunity for spontaneous mutations to occur is also limited. However, men produce sperm from adolescence to death, creating the need for countless cell divisions, which can develop genetic errors that create spontaneous mutations in gametes.

Yuki888 [10]

Answer:

3/8

Explanation:

I think I can help with completing the question.

Above each punnet square, the genotypes of the parents were given right? something like this:

Parent 1 fur genotype: Ff                             Parent 1 eye genotype: Ee

Parent 2 fur genotype: Ff                            Parent 2 eye genotype: ee

       F         f                                                              E        e

F     FF       Ff                                                    e     Ee      ee

f      Ff        ff                                                     e     Ee      ee

Probability of black fur if dominant is:               Probability of red eyes:

    3/4                                                                       2/4= 1/2

Probability of a trait combination such as black fur and red eyes is

3/4*1/2 = 3/8.
