Answer:

Because haploid organisms have only one set of chromosomes

Explanation:

Haploid organisms, unlike diploid that contain two sets of chromosomes (2n), have only one set of chromosomes (n). This means that they only have one gene copy and one allele (variant) for that gene. So, there is no recessive or dominant relationship.

Humans are diploid organisms, meaning that their cells have 2n chromosomes with the exception of gametes. Gametes are formed during the reduction division (meiosis) in which chromosome number is reduced to half.

So, when to gametes fuse, during the fertilization, formed new organism contain two sets of chromosomes (one from father and one from mother).

As the coach of the team, it is good advice for athletes to keep strictly to their training schedule. Consistency is more important than periodic but prolonged training. This is because the latter tends to wear out the athlete physically and creates longer come-back inertia.

<h3>What is a Training Schedule</h3>

A Training Schedule is a plan that you must design to ensure that you support a team of athletes with the required amount of training. A properly designed schedule will contain:
