If a cross between true-breeding red-flowered and true-breeding white-flowered plants give rise to pink-flowered progeny, what is the mode of inheritance?

Correct Answer: Incomplete dominance
Incomplete dominance involves the blending of characters in the progeny that are heterozygotes. Here red and white-flowered plants produce pink-flowered progeny. Hence this is an instance of incomplete dominance.

In a genetic cross between the genotypes WWXX and wwxx, the following phenotypic distributions were observed among the F2 progeny: WX, 562; wx, 158; Wx, 38; and wX, 42. Likewise, a cross between XXYY and xxyy yielded the following results: XY, 675; xy, 175; Xy, 72; and xY, 78. Similarly, a cross between WWYY and wwyy yielded: WY, 292; wy, 88; Wy, 12; and wY, 8. In all the genotypes, capital letters denote the dominant allele. Assume that the F1 progeny were self-fertilized in all three crosses. Also, double cross-over does not occur in this species. Which of the following is correct?

Which of the following statements about gene therapy are correct?
P. Affected individuals, but not their progeny, can be cured through germline gene therapy.
Q. Affected individuals, as well as their progeny, can be cured through germline gene therapy.
R. Affected individuals, but not their progeny, can be cured through somatic gene therapy.
S. Affected individuals, as well as their progeny, can be cured through somatic gene therapy.

True breeding Drosophila flies with curved wings and dark bodies were mated with true breeding short wings and tan body Drosophila, The F1 progeny was observed to be with curved wings and tan body. The F1 progeny was again allowed to breed and produced flies of the following phenotype, 45 curved wings tan body, 15 short wings tan body, 16 curved wings dark body and, 6 short wings dark body. The mode of inheritance is

A cam should be designed only using uniform rise and fall within half of the cam, the remaining is dwell period, and without any dwell period in between the rise -fall periods and rise and fall periods should be same. The maximum rise in follower is 30 mm. How much the follower will rise when the follower is 120 degrees from its initial position of a cam?

A cam should be designed only using uniform rise and fall within half of the cam, the remaining is dwell period, and without any dwell period in between the rise-fall periods and rise and fall periods should be same. The maximum rise in follower is 45 mm. How much the follower will rise when the follower is 45 degrees from its initial position of a cam?

A cam should be designed only using uniform rise and fall within the second half of cam profile, the first half is dwell period, without any dwell period in between the rise and fall periods and rise and fall periods should be same. The maximum rise in follower is 45 mm. How much the follower will rise when the follower is 120 degrees from its initial position of a cam?

A cam should be designed only using uniform rise and fall within the second half of cam profile, the first half is dwell period, without any dwell period in between the rise and fall periods and rise and fall periods should be same. The maximum rise in follower is 55 mm. How much the follower will rise when the follower is 240 degrees from its initial position of a cam?

Consider the following statements and choose the correct answer:
1. Intense or strong light retards the growth of shoot
2. Shade plants are shorter and stockier than sun plants
3. Shade plants have dense covering of hairs while sun plants are less hairy
4. The stems of shade plants are taIler and more branched than that of sun plants

Consider the following statements and choose the correct answer:
1. A direct proportionality exists between vapour pressure and the concentration of water vapour in the atmosphere
2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity
4. A rise or fall in vapour pressure with no change in temperature will be accompanied by a rise or fall, respectively, in relative humidity
