Answer:

mutualism -Both species benefit

commensalism- One species lives with, on, or in another species (the host). The host species neither benefits nor is harmed from the relationship. The species that lives on the host is benefited.

parasitism - One species (the parasite) lives with, on, or in a host species, at the expense of the host species. Unlike in predation, the host is not immediately killed by the parasite, though it may sicken and die over time.

predator/prey -One species (the predator) hunts and kills another species (the prey)

competition -The struggle among organisms for the same limited resources in an ecosystem

Answer:

The genotype of the father: Ff

The genotype of the mother: ff

The genotype of the two children without freckles: ff

The genotype of the two children with freckles: Ff

Explanation:

Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles.  Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype.  In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.

A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).

Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
