The purpose of this experiment was to observe the process of heredity and genes. To be able to perform it, I studied how and why Mendel tested genes. I also studied about different types of genes. When performing this experiment, I kept track of homo-zygous and hetero-zygous traits, as well as those that are dominant and/or recessive. My assigned experiment was to breed one male and female mouse together to make a litter of ten mice. The first round I bred two mice with black fur and the same eye color. After creating a litter of ten, I resulted with all the offspring having black fur, relevant to my hypothesis that most or all of the litter would have black fur.
At this point, I predicted that black fur is dominant and white fur is recessive. To test this prediction, I performed the same experiment again, except with one white mouse and one black mouse with the same eye color this time. I watched carefully with each offspring born, but they all were black. I recorded these results down and continued on with the next round.
In the next round, I bred one mouse with white fur and red eyes with a mouse with black fur and regular eyes. This time, however, nearly 75% offspring donned white fur, while the rest had black. All offspring had regular eyes instead of the red eyes.
After performing this experiment, I came to the conclusion that black fur is a dominant trait and white fur is recessive. Even though three-fourths of the last litter had white fur, black fur was still more common throughout the whole experiment.

Based on the results of the cross, it can be concluded that both parents were heterozygous for black fur color and that black fur color is dominant over white fur color.
What are dominant and recessive traits?
Dominant traits are characters which always appear in the offspring of every generation.
Recessive traits are characters which only appear in the absence of the dominant trait.
In the project, a cross was made between offspring of a cross between a black fur color rabbit and white fur color rabbit who all had black fur color.
The results showed that 75% of offspring had black fur and 25% had white fur.
Therefore, it can be concluded that both parents were heterozygous for black fur color and that black fur color is dominant over white fur color.
