The most likely explanation for the variation is the offspring were produced from different combination of genes. A single pair of gold fish mentioned in the question means a male and a female gold fish. The two of them mated and contributed different genes to the fertilized fish eggs, this results in production of various body shape and colouration which is known as variation.
Closely related but different, distantly related but similar
The oceanic crust gets carried underneath another tectonic plate and it sinks hundreds of miles into the Earth's Mantle.
<h2>The three factors that influence </h2>
There are three factors which influence the value given to particular fiber identification are described as:
1. Shape of a man made fibre that are usually machine or hand made.
2. Fibre color with variety of different colors.
3. Fibre number with numerous numbering options
These above all affects the degree of fibre transfers.
Answer:
b. multicellular fungus
Explanation:
In a recent study, it was discovered that there was a genetic relationship between multicellular organisms like protozoa and animals and fungi have a common ancestor as their ancestors had contact about 1.1 billion years ago.
Therefore, the organism that was most likely the most recent common ancestor of all animals is multicellular fungus
