In fruit flies long wings (w) are dominant to short wings. what is the phenotype of the known parent

Hello. This question is incomplete. The full question is:

"In fruit flies long wings (W) are dominant to short wings (w).

what is the phenotype of the known parent?

a. wingless  b. short winged  c. medium winged  d. long winged"

It is not possible to respond through the information given.

Explanation:

In the question above, we learn that within a population of fruit flies, the "W" allele is the dominant allele and represents long wings, on the other hand, the "w" allele is the recessive allele and represents short wings.

Although this information is given, we cannot state the genotype of the known parent, if the genotype of an offspring has not been informed.

However, we can affirm that the parents that present the "ww" genotype will be considered short winged, while the parents that present the "Ww" and "WW" alleles will be long winged.

answer: the blood-brain barrier is a layer of specialized membranes and cell processes designed to keep undesirable substances from passing from the bloodstream into the precious tissues of the brain. while the blood-brain barrier does keep most bad things out of the central nervous system, it is not impermeable.

explanation:

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
