The fungus Melampsora lini causes a disease known as flax rust. Different strains of M. lini cause varying degrees of the rust disease. Conversely, different strains of flax are resistant or sensitive to the various varieties of rust. The Bombay variety of flax is resistant to M. lini-strain 22 but sensitive to M. lini-strain 24. A strain of flax called 770B is just the opposite; it is resistant to strain 24 but sensitive to strain 22. When 770B was crossed to Bombay, all F1 individuals were resistant to both strain 22 and strain 24. When F1 individuals were self-fertilized, the following data were obtained:

43 resistant to strain 22 but sensitive to strain 24
9 sensitive to strain 22 and strain 24
32 sensitive to strain 22 but resistant to strain 24
110 resistant to strain 22 and strain 24

Required:
Explain the inheritance pattern for flax resistance and sensitivity to M. lini strains.

Answer:

Explanation:

Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.

From the data set given, the total number of the population is:

43+9+32+110 = 194

However, their ratio are being calculated as follows:

43/194 = 0.22

9/194 = 0.05

32/194 = 0.16

110/194 = 0.57

After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.

i.e.  

3/16 = 0.18

1/16 = 0.06

3/16 = 0.18

9/16 = 0.56

The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.

You are performing an experiment with Primase, using a specific DNA template. In this experiment, you provide NTPs (ATP, UTP, CTP, GTP) which contained only one radioactive phosphate group, in the alpha-phosphate position (the alpha- phosphate is the one attached to the sugar. the other phosphates are beta and gamma). After RNA synthesis occurs, you separate the resultant RNA strand any of the NTPs that have not been incorporated into the RNA, and measure the radioactivity of the newly synthesized RNA.A) In this experiment, would you expect the newly synthesized RNA be radioactive? Explain why.B) If you forgot to add CTP when you did the experiment, would the resulting RNA be radioactive?C) If you did the experiment, with all the NTPs provided, but only the beta phosphate was radioactive for each of the NTPs, would radioactivity be found in the RNA? Explain why.D) If you did the experiment, with all the required NTPs, but only the ATP was radiolabelled Would radioactivity be found in the RNA? Explain why.

You are curious about the effects of different watering schedules on your favorite fruit, strawberries. You set up plants, all the same age and size, and plant them in identical pots with the same potting soil. You water them once a week, every day, or every other day. Every day, you check the plants for strawberries, and record the number and size of the berries produced by each plant.

Why do thermos bottle keep cold beverages contained inside them from getting warm?

In humans, the dominant allele N causes an abnormal shape of the patella in the knee, whereas n is the recessive normal allele. A separate gene is concerned with finger length, and the dominant allele B causes abnormally short fingers, whereas b is the recessive normal allele. A study focused on people who have both abnormal patellae and short fingers. These individuals were N/n . B/b in genotype, having inherited the N allele from one parent and the B allele from the other parent. These N/n . B/b people mated with normal spouses, producing 40 progeny classified as follows: Normal 3 Abnormal knees and short fingers 2 Abnormal knees only 17 Short fingers only 18

Explain why the four types of children were found in the proportions shown.
