Answer:
The estimated number of green seeds in the F2 generation is 2007, approximately.
Explanation:
<u>Available data:</u>
- Cross of a true-breeding plant that produced green seeds with a true-breeding plant that produced yellow seeds
- The entire F1 generation produced yellow seeds.
- Cross of the F1 offspring with each other to produce the F2 generation
- From the F2 generation, there were 6022 yellow seeds.
<u>1st Cross:</u>
Parental) YY x yy
gametes) Y Y y y
F1) 100% Yy
<u>2nd Cross</u>
Parental) Yy x Yy
Gametes) Y y Y y
Punnet square) Y y
Y YY Yy
y Yy yy
F2) 75% yellow, Y-
25% green, yy
What is a likely estimate of the number of green seeds he collected from the F2 generation?
From the whole F2 generation (100%), 75% are yellow seeds, which means that the remaining 25% are green seeds. According to this, 75% of the seeds, equal 6022 seeds. So we need to know how many seeds equal the 25% of green seeds. This is:
If 75% of the F2 generation ------- 6022 seeds
then 25% of the F2 generation -----X = 2007.333 seeds
<em>The estimated number of green seeds in the F2 generation is 2007, approximately. </em>
What are the answer choices
Answer:
62
Explanation:
31 pairs
A mule is the offspring of a male donkey (a jack) and a female horse (a mare). A horse has 64 chromosomes, and a donkey has 62. The mule ends up with 63. Mules can be either male or female, but, because of the odd number of chromosomes, they can't reproduce.
Answer:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. The light-independent reactions are sometimes called the Calvin cycle because of the cyclical nature of the process.
