In Drosophila, white eyes is caused by a recessive allele (w) located on the X chromosome. The dominant allele (W) produces red
eyes. Suppose a white-eyed female mates with a red-eyed male. Knowing this, complete the sentences with the correct terms.
1) Among the male F1 offspring, the predicted proportion with white eyes is _____.
2) Among the female F1 offspring, the predicted proportion with white eyes is ____.
3) The genotype of the male is best represented as ______.
4) The genotype of the female is best represented as _____.
5) Among all F2 offspring, the predicted proportion with white eyes is ______.
In the first generation of crossing of red eyed male with white eyed female, the male become dominant having red eyed offspring . This is due to the presence of recessive allele in the female, so all the offspring produce in F1 generation are 100 % red eyed while in F2 generation half offspring are white and half are red eyed. The recessive allele is represented by small letters while dominant allele is represented by capital letters.
Drosophila is a genus of flies, belonging to the family Drosophilidae.These question have to do with the inheritance and using the brief description above to get results by completing the terms .
Hubble's brilliant observation was that the red shift of galaxies was directly proportional to the distance of the galaxy from earth. That meant that things farther away from Earth were moving away faster. In other words, the universe must be expanding.
The larger cell would be able to get rid of the waste faster! The greater the surface-area to volume ratio of a cell, the easier it is for the cell to get rid of wastes and take in essential materials such as oxygen and nutrients through the plasma membrane!
