Case A

I have done two replicas of this case where the crossing of homozygous wild females and homozygous sepia males has been performed.

Replica 1 was much more advanced since the crossings were made sooner.

In this first image it is seen in the flask pupae. It means that it has been about six days after the four sepia males and four wild females have been placed.

In the second image the images have already appeared and can be counted, the flies are killed so that they do not reproduce between them and can contaminate the results of the experimental check.

in the third image it is seen already with the binocular magnifying glass looks at the color of the eyes of the offspring of the parental genesis.

Replica 2 was started two weeks later because the CESIRE flies of the homozygotes did not reproduce and we had to wait.

In image 1 we see "black dots" that are eggs of drosophylls and larvae (viscous and yellow) that rise to the filter paper to follow the third phase of the life cycle that is to become a pupae, and for this reason they need this support.

In the second image, the most advanced case is seen where the imagos already exist and the count can be made.

In the third image are sleeping drosophiles to be able to observe with the binocular magnifier the color of the eyes, to be able to do the χ² test, as can be seen in the photograph, all the drosophiles have red eyes, as it says Mendel's first law, in Case A is not tied to sex.
