An organism's trophic level refers to the food chain position that it occupies. Producers always occupy the Trophy level 1, Primary Consumer occupies the Trophy level 2, Secondary Consumer has the Trophy level 3 and the Tertiary level fills in the Trophy level 4.
Answer: The genotype for the parent organism whose genotype is unknown is Ff.
Explanation: Let (F) represent the allele for purple which is dominant over (f) and (f) represent the allele for white.
The parent organism whose genotype is unknown is heterozygous for purple colour (Ff).
A cross between Ff and ff will produce four offsprings: two of which are Ff (heterozygous for purple colour) and two are ff (white).
Ff x ff = Ff, Ff, ff and ff.
Since (F) is dominant over (f), (Ff) will manifest as purple while (ff) will manifest as white. Therefore, half of the offsprings are purple while the other half are white.

<span>The difference that you are searching for is the addition of Appendages. They appeared in Cambrian animals and were used to increase their physical capabilities like when sensing and processing the information found in the environment. Common appenadges found in animals are things like antennae found in insects that are used to help them communicate or notice things or similar things.</span>
