<span>This fact pattern best fits the idea of the Gradualism Model. This particular model focuses on how species slowly grow and change through evolution over time. Essentially, the model is that species will very slowly change into another type of species as time passes.</span>
Answer:
1. 8 copies of each gene in somatic cells
2. 4 copies of each gene in gametes
Explanation:
According to the question, strawberry is an octoploid organism (8n). This means that it contains 8 sets of chromosomes in its genome. If it contains 8 copies of each chromosome, then it also contains 8 copies of each gene in its body or somatic cell (4 copies from each parent).
However, it will produce gametes or reproductive cells via meiosis. Meiosis is a kind of cell division that reduces the chromosomal number by half. Hence, an octoploid strawberry (8n) with 8 copies of genes will undergo meiosis to produce gametes that have 4 copies of each chromosome and hence, four copies of each gene i.e. 4n (tetraploid).

The organs which perform same function and looks but they are different in their structure from each other are called as analogous organs.
Organs are the structures that made up of two or more tissues organized to carry out a particular function.
An organ or bone that appears in different animals with the same function is called homologous structure.
Homologous organs have similar origin n basic structure but perform different functions in different organisms. Analogous organs are different in basic structure but perform same functions.
Examples :
The arm of a human,the wing of a bird or a B at, the leg of a dog and the flipper of a dolphin or whale are homologous structures.
The forelimbs of all mammals have the same basic bone structure. The structures are all similar because they envolved to do the same job.
