The pieces of bread which are on the either side of what is called the sandwich generation are called parents and children which is then the answer. Hope this is correct and this will help in the said homework then.
Answer:
See the answer below
Explanation:
a) The mode of inheritance of the bar mutant is X-linked and dominant.
Assuming that barness is represented by the allele B.
Bar female = 
or 
Wild type male = 
Bar female x wild type male:
x
All of the F1 flies are bar because a single B allele is required for the trait to be expressed.
Bar male x wildtype female
x 
All the female offspring are barred while all the males are wildtype barred resulting in a 50/50 (857/905 is approximately 50/50) ratio of barred/wildtype offspring.
b) Genotypes of each of the cross above, including the parents and the F1 generations.
1. x
2. x
Answer:
increases the chance that some organisms will survive a major change in the environment
Explanation:
Answer:
The answer is C.
Explanation:
The initial proportion of 90% light-brown (sand-like) colored fish to 10% mottled fish is the result of the light-brown fish mixing with their background and thus being preyed less by the birds than the mottled fish which are of course more visible above a light brown sandy bottom. The higher predation results in the removal of more mottled fish and thus a smaller number of these fish in the population. When the gravel is added to the bottom of the lake, this situation reverses. Suddenly the light brown fish are more visible to the birds and we can expect that their numbers will decrease, while the mottled fish will become more numerous as they will be harder to spot and capture by the birds, and will therefore survive more than their pale counterparts.
