An organism grown in a high nutrient liquid broth to high turbidity always appears to produce a blue pigment and even when a large inoculum is transferred to a nutrient rich agar plate it appears blue. When the researcher noticed it never appears blue when very small colonies were grown in low nutrient agar plates. What is the most plausible conclusion?

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?
