Give 5 examples each of mutualism, communalism, and parasitism.

<span>1. Mutualism is a type of relationship that can be seen between two individuals of two different species to obtain benefits for both of individuals.

Examples : Coral polyps and zooxanthellae
                   bee and flower
                   Lichens
                   Rhizobium and root nodules
                   Ungulates and bacteria which live in their intestines

</span><span>2. Commensalism (this is the correct word) is a type of relationship between two organisms which belonged to two different species that one individual obtains benefits while other doesn't have any harm or benefit.

Examples : Remora and sharks
                   Orchids and trees
                   Pseudoscorpions and Beetles
                   Cattle Egrets and Livestock
                   hermit crab and sea anemone
</span>
3. Parasitism is a relationship between two organisms of two different species where one individual (parasite) gets benefits by harming other individual (host).
 
Examples : <em>Cuscuta</em> (parasite)<span> and angiosperms (host)
                    Parasitic viruses (parasite) and human (host)
                    Tape worms (parasite) and pigs (host)
                    Flukes (parasite) and human (host)
                    Parasitic bacteria (parasite) and human (host)</span>

In Oompa Loompas, gray face (G) is dominant to orange recessive face (g). If two gray faced Oompas have an offspring with an ora
Neko [114]

Answer:

The genotype for each of the parents must be

parent 1 : Gg

parent 2 : Gg

Explanation:

Please note that a dominant trait is a trait that is expressed phenotypically in a heterozygous state, while a recessive trait is a trait that can only be expressed in a homozygous state.

Now, since gray face (G) for Oompa Loompas is dominant, and orange face (g) is recessive, for an offspring to be orange faced, it means that the genotype of the offspring must be 'gg'. Also, since both parent contribute an allele in the pair of alleles in the offspring, both parents must have the recessive (g) in their genotype. Moreover, we are told that both parents are gray-faced, meaning that their genotypes were 'Gg' and 'Gg'. To confirm, let me do the cross

                                 G           g

G                                GG       Gg

g                                 Gg        gg

from the cross above, we find out that out of 4 offspring, 3 were gray face (GG, Gg ) while one was orange face (gg).
