The correct answer is B.
Genetic drift is one of the four evolutionary mechanisms. It changes the frequency by chance, aka at random.
For example. if you have 100 frogs in the population, 20 red, 20 green and 60 yellow, not all of the alleles are going to be passed down to the next generation because a portion of the population can be affected by a random event such as the flood. So, if the flood accidentally kills 20 red frogs, none of the offspring are going to be red by chance.
<span>Plants use carbon dioxide and sunlight to make their own food and grow the carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels most of the carbon quickly enters the atmosphere as carbon dioxide :) i love biology</span>
Answer: Antipararell strands
Explanation:
The feature of the DNA is antipararell strands
Continuous and discontinuous replication is as a result that the two strands in a DNA molecule runs antipararell, which means one strand run in the 5' to 3' direction, while the other is in the 3' to 5' direction.
The strand which is discontinuously synthesized is referred to as the lagging strand.
Discontinuously synthesized strand produce small DNA molecules attached to its own primer RNA called the okazaki fragments.
In order for a recessive trait to be apparent in an organism, the organism must receive a copy of the allele for that trait from both parents.
Let the:
black coat: B
brown coat: b
Trotter: T
pacer: t
The offspring received both of the recessive alleles because it demonstrates the recessive phenotypes. Therefore, they genotype of the offspring is:
bbtt
The black horse that is a pacer that can produce this offspring will be:
Bbtt
Therefore, the brown horse's genotype must be:
bbTt
The offspring will receive b from both parents and t from both parents.
