Answer:
Pollination is a form of sexual reproduction and adds new gene combination to the progeny. These new gene combinations impart new genetic traits to progeny.
Explanation:
Pollination includes landing of pollen on the stigma of the same flower or another flower of same species. Since it is followed by fusion of male and female gamete to form an embryo, new gene combination and new genetic traits are imparted to the progeny.
Since the Dr studies genetic traits, sexual reproduction in the plant would allow him to observe more genetic variations in the traits.
Answer:
According to the Food Lovers Companion, The name "hamburger" comes from the seaport town of Hamburg, Germany, where it is thought that 19th-century sailors brought back the idea of raw shredded beef (known today as beef tartare) after trading with the Baltic provinces of Russia.
The answer is <span>C) Bb x Bb
</span>
B - the allele for black and white coloration
b - the allele for brown and white coloration
There are in total 11 offspring (<span>8 black and white and 3 brown and white),
In a monohybrid cross when both parents are heterozygous (Bb), the phenotype ratio is 3:1. We have ratio 8:3.
The ideal ratio would be 9:3 because it is the same as 3:1.
Therefore, the parents Bb and Bb will have </span>8 black and white and 3 brown and white with the ration 8:3 ≈ 9:3 = 3:1
Answer:
an increase in sucrose in food would increase the sucrose concentration inside the body thus increasing sucrase activity until it reaches its saturation point (approx 30g/l) if im correct
The answer is no, they are just two varieties of the same species adapted to different environment.
The change in moth color was caused by natural selection which favored the color more suitable for a certain conditions. Thus, in dark background, dark-colored moths could camouflage and escape from the predator (birds). So their chances for the survival and reproduction were higher than those of light-colored moths. When the pollution was reduced, the light colored moths were beneficial for survival.
So, the conclusion is that changes in the environment caused changes in the characteristics that were most beneficial for survival.
