Answer:

<h2>Pre-zygotic factors; post-zygotic factors </h2>

Explanation:

Fertilization is the process of fusion of  male gamete (sperm) and female gamete (egg). Before fertilization, all the events are known as pre-fertilization events and those which occurs after fertilization are known as post-fertilization events.

There are various factors which help in fertilization. All species contain some receptors on the membrane of egg which play very important role in fertilization and prevent fertilization between inter-species.

The mating in which the formation of zygote is occurs but it is unable to form a viable embryo,  is due to the result of post-zygotic factors.

vredina [299]

The phenotype of antenna in crawfish depends on the protein amount in the antenna length. The offspring have different phenotype than their parent because of the amount of protein translated from each parent gene is determining in this.

The gene determines the amount of protein to be present in the antenna to determine its length.

Explanation:

Data given:

Two crawfish parent = medium length antennae, genotyoe Ll

One offspring = short antenna, genotype ll

one offspring = long antennae, genotype LL

The traits in offspring is shown as:

       L    l

L   LL    Ll

l   Ll     ll

The proportion of allele present in the gene determined the length of the antenna in crawfish.

The difference in length of the antenna in crawfish is due to the amount of protein for the phenotype present in the individual. The amount of protein to be expressed in the crawfish is given by both the parents. The tendency of protein expresed define the phenotype of antenna length.
