Answer:
50%
Explanation:
If black is dominant to white color and crossing with parents produced some progeny which were black and a white progeny then it simply indicates that parents were heterozygous for the trait even if phenotypically they appeared black. A cross between parents is shown as under:
Parents
Bb x Bb
Progeny: BB Bb Bb bb
BB and Bb allelic combinations produced a black mice while bb combinations produced white mice.
Now the subsequent cross between one of the parents and white off spring is shown as under:
Bb x bb
Progeny: Bb Bb bb bb
It is clear from the cross above that the progeny with Bb allelic combinations will be black while with bb combinations they will be white. 2 out of the 4 progeny are genotypically bb that means they are white i.e. 50% progeny are white.
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
Answer: It is during the Exponential or Log phase
Explanation:
The rock layer on the bottom will decompose and either turn to sand, gravel, or blend in with the dirt (but most likely not the last one).
Answer:
Sexual reproduction produces genetically different offspring from two parents while asexual reproduction produces genetically identical offspring from one parent.
Sexual reproduction will see to the offspring taking half of their genetics from the father (male), while the other half comes from the mother (female). The offspring would further inherit based on whether the traits are dominant or recessive. However, in asexual reproduction, there is only one parent, so all the traits are passed down.
