Answer:
24%
Explanation:
The given genetic trait is homozygous recessive and the frequency of homozygous recessive genotypes in the population is 2%.
Therefore, frequency of homozygous recessive genotypes (q2) = 2% = 0.02
Frequency of homozygous recessive allele (q) = square root of 0.02 = 0.141
Since p+q =1 (here, p = frequency of dominant allele).
So, p= 1-q = 1-0.141 = 0.859
The frequency of heterozygous carrier genotypes in the population = 2pq = 2 x 0.141 x 0.859 = 0.24 or 24%
Answer:
All plants of purple colour.
Explanation:
All the offspring plants of F1 generation have purple leaves because Ay is dominant allele which appear in the leaf colour instead of A2 which is a recessive allele. In the F1 generation, the dominant allele must appear in the shape and structure of the offspring whereas the recessive allele does not appear so offspring of purple leaves appear if plants have purple leaves cross with white leaves.

We must take measures to reduce our carbon footprint! There are so many options we can take. We can start to produce, and invest in, more solar and wind powered solutions to produce our electricity. We can also cut down on our reliance on gas powered vehicles to move us everywhere. If we were to invest more in electric powered vehicles, start to use more bicycles, or even carpool and take the bus more we could greatly reduce our carbon footprint.
Person two
You talk about all of these “amazing ways” we can reduce our carbon footprint, but you haven’t even considered the inconveniences and the cost of these ways. Solar and wind powered options don’t produce nearly as much power as a coal plant! Not to mention the cost of them. Gas powered vehicles have been around for 100 years, and electric cars haven’t been around for nearly as long and they are very expensive! Also, in the winter, not everyone wants to be freezing cold on a bike, and not everyone has a friend or coworker they can carpool with.
Person one
First of all, I know that these methods would be expensive at first, but if we were to actually take them seriously then they could become inexpensive, and reduce our carbon footprint. The electric car may be newer, but it reduces the carbon output greatly. Investing in these is key in creating a greener future for future generations, and if we don’t reduce our carbon output soon there might not be a planet left for our future generations! All of these methods might seem expensive at first, but in the long run cost will go down, and the high cost at first will be worth it if it means reducing our carbon footprint. Therefore I believe it is necessary that we reduce our carbon footprints, and these are just a few of the ways how.
Person two
You have no way of knowing that the methods would become cheaper over time. They may only grow in cost, while our coal and oil prices have been steady and low for a long, long time. Investing in these ideas would mean taking away money that could be funding more important things such as space travel, or deep sea exploration. Why do you think that there may not be a planet left for future generations? Just because we aren’t reducing our carbon output doesn’t mean we won’t have a planet to live on. I believe that we should not focus on reducing our carbon output because we have much more effective methods of producing electricity and traveling than solar and wind powered devices.
