Tortoise shell cats can be explained as the offspring from a incomplete dominance cross. Incomplete dominance gives rise to an intermediate phenotype.

As stated earlier, the tortoise shell colour is as a result of incomplete dominance but as it exists only in females, the inheritance is X linked. This means the tortoise shell colour is inherited in the heterozygous condition as females have two X (XX) and males (XY) can only be either of the parent's true breeding genotype.Learn more about X- linked traits: https://brainly.com/question/14548821

1. How do fossils form?
Explanation:
There is a LOOOONG process for this so here it is;
First things first.The animal dies. Soft parts of the animal's body, including skin and muscles, start to rot away. Scavengers may come and eat some of the remains. Before the body disappears completely, it is buried by sediment - usually mud, sand or silt. Often at this point only the bones and teeth remain. Many more layers of sediment build up on top. This puts a lot of weight and pressure onto the layers below, squashing them. Eventually, they turn into sedimentary rock. While this is happening, water seeps into the bones and teeth, turning them to stone as it leaves behind minerals. This process can take thousands or even millions of years.
