For my experiment, I wanted to see if the wild type is dominant in all the features, so I mated a wild type female to a male that that had different type of feature for each features (ex. Wild type female and yellow body male, wild type female and eyeless male, etc). What I found was that the wild type is dominant for all features EXCEPT Antennae, Eye Shape, and Wing Angle.

For the second part of my experiment, I mated a wild type female with a dichate angled male. The results showed that it was a 1:1 ratio of wild type and dichate angled. This told me that although the dichate wing angle is dominant over the wild type, a dichate wing angled fly has a heterozygous genotype (D+), since a homozygous genotype (DD) would result to all dichate wing angled offsprings.

Next, I mated two dichate wing angled flies, and it showed that the ratio of offspring was 1:2, wild type:dichate respectively. An explanation for the ratio being 1:2 instead of out of 4 is that one quarter of the offspring is DD, which may indicate lethal genes, and thus does not exist.

These results were similar when I mated two aristapedia (antennae) as well as two flies with different shaped eyes. This indicates that although these three features are dominant over the wild type, it does not mean that they are homozygous genotypes, but rather heterozygous. This phenomenon also tells us that there are such lethal genes that some offspring can inherit, which leads to death, such as sickle cell anemia in humans.
