Some "cleaner fish" consume parasites and mucus from the skin of larger fish. What would be a reasonable argument for why this could be a mutualism rather than a commensal relationship? (3 points)

The cleaner fish prefer to consume mucus from the larger fish rather than parasites.
The cleaner fish reduce the number of parasites on the larger fish.
The larger fish are healthier when the cleaner fish are not present.
The larger fish have no difference in parasite load when the cleaner fish are present.

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?

Can someone i have no idea of how to do this.
