For predicting breeding value of a cow on basis of Information on Itself, Its dam and paternal half sibs we use (a) Analysis of variance technique ( b) Maximum likelihood technique (c) Multiple correlation technique (d) Multiple regression technique
For predicting the breeding value of a cow based on information on itself, its dam, and its paternal half-sibs, the most appropriate technique is: (d) Multiple regression technique Multiple regression allows the inclusion of various sources of information (the cow itself, its dam, and its paternal half-sibs) to predict the breeding value by estimating the contribution of each factor. This method effectively combines these different pieces of information to make the best prediction of the breeding value.
Hello, I am having trouble understanding the answer for this question and I was wondering if you could help me with it? You have at your disposition a restriction enzyme E, which recognizes DNA and cuts it as shown below. If you have DNA fragments cut with enzymes E, F, G, or H, which can you ligate to another piece of DNA cut with E? SELECT ALL THAT APPLY DNA cut with enzyme G DNA cut with enzyme E DNA cut with enzyme F DNA cut with enzyme H The answers are DNA cut with enzyme G and DNA cut with enzyme E. I sort of understand why DNA cut with enzyme E is correct but I don't understand why DNA cut with enzyme G is correct. I was working out the problem and I thought DNA cut with enzyme H makes more sense than DNA cut with enzyme G. I would greatly appreciate your help.

Can you please answer this question sir.... In a given species of flowering plant the colour of the seeds is exclusively determined by the color of its seed coat. Seed coat colour in this species is determined by the nuclear gene with two alleles. The white W allele is dominant over brown w allele. If a plant with brown seeds ww is crossed as a female with pollen from a white seed WW plant what will be the seed color and the genotype of the embryo in the resultant seeds obtained from this cross Brown seeds with Ww embryo (answer) White seeds with Ww embryo Brown seeds with ww embryo White seeds with ww embryo Now it is brown seeds with Ww embryo as the answer. Is it because the seed coat is from the female parent and female parent is brown. But the progeny of the cross embryo is Ww because embryo colour is not determined by the seed coat
If the amount of variation in height that is associated with variation in weight Is 49%, what Is the correlation between these variables? Ans : 0.7 I know it is solved by underroot but why , can you please explain sir
The variable that is the Correlation Coefficient is R^2. To cancel out a ^2 in a variable, you take the square root on both sides. So in this case, convert percentage into a decimal. 49% = 0.49. R^2 is equal to 0.49. Then, take the square root on both sides to get R by itself. √R^2 = √0.49. R = 0.7

Highest genetic gain can be achieved by accurate estimation of breeding value of (a) Sires of dams (b) Dams of sires (c) Sires of sires (d) Dams of dams What should be the correct ans ans why ?
The correct answer is (c) Sires of sires. Accurate estimation of breeding values for sires of sires (grand sires) tends to yield the highest genetic gain because these sires contribute significantly to the next generation's genetic makeup. They have a broader influence on the gene pool due to the number of offspring they produce, which in turn becomes parents themselves. Therefore, focusing on accurately assessing the breeding value of sires of sires ensures that the beneficial traits are effectively passed on and amplified in the population.

Brown seeds with Ww embryo (answer)

Brown seeds with ww embryo
White seeds with ww embryo
Now it is brown seeds with Ww embryo as the answer. Is it because the seed coat is from the female parent and female parent is brown. But the progeny of the cross embryo is Ww because embryo colour is not determined by the seed coat
White seeds with Ww embryo

1:2
1:4

Zero
This couple have 50% (1/2) chances that their child will be Rh + so 1/2 x 1/2 x 1/2=1/8 for all 3 to be Rh+. or 1 to 8 or 1:8
