You can use a Punnet Square to figure it out. For example, if gray elephants dominate over brown elephants, and you cross 1 homozygous gray elephant (GG) and one homozygous brown elephant (gg), the Punnet square predicts that the offspring will all be heterozygous Gg. They will all be gray, however, because gray dominates over brown.
In this scenario, all the offspring would have gray body color, as it is the dominant trait over black body color. Therefore, all 200 offspring would have gray bodies.

If black body color is recessive and gray is dominant, we can assume that the black body color is represented by the genotype "bb". Given that gray is dominant, individuals with gray bodies could be either "GG" or "Gg". Thus, for black body color to appear in offspring from two gray-bodied flies, both parents would need to be carriers of the black body allele (each "Gg" or "gg"). Therefore, if both parents are carriers, the expected ratio of black-bodied offspring would be 25% (1/4). In a sample size of 200 offspring, we would expect around 50 flies to have black bodies.
In this case, if both parents are heterozygous (Gg for gray and gg for black), their offspring would be expected to follow a 3:1 ratio of gray to black body color. Therefore, out of 200 offspring, approximately 150 would have gray body color and 50 would have black body color.
Segments of DNA that contain instructions for creating specific traits or proteins are transferred from parent to offspring and are called genes. Genes determine many of an individual's characteristics, such as eye color, height, and susceptibility to certain diseases. Genes are passed down through generations and are responsible for genetic inheritance.
In this scenario, all the offspring would have gray body color, as it is the dominant trait over black body color. Therefore, all 200 offspring would have gray bodies.

Half of the offspring, or 100 rabbits, would be expected to be white when offspring from a heterozygous brown rabbit and a white rabbit are produced. This is due to the dominant-recessive inheritance pattern where brown is dominant and white is recessive.
Violet is the dominant color used in the painting Wisteria. Monet chose to use the actual color of the flowers as the back ground color in order to create a dominant effect.
This is a basic Mendel cross where the master himself found out that yellow was the dominant color to green. Many years later we found out that there is another gene involved and that the colors have to do with chlorophyll - not just color. If a pure green is crossed to a purebred yellow, then all the offspring will be yellow. However they do carry the green gene since if these yellow offspring are self-fertilized, they will produce the standard 3/4 yellow and 1/4 green phenotypes.
