In 1997, the first transgenic cow, Rosie, produced human protein-enriched milk. The milk contained the _________ and was nutritionally a more balanced product for human babies than natural cow-milk.

Which one of the following options will express intermediate skin colour in an individual?

Which of the following statements is true?

MONOHYBRID CROSS
The inheritance of flower color in the dog flower (Snapdragon or Antirrhinum sp.) can be understood by crossbreeding between true-breeding red-flowered (RR) and true-breeding white-flowered plants (rr). When they were crossed, F₁ (Rr) was pink. When F₁ was self-pollinated, the F₂ results were Red, Pink and White. Here the genotype ratios were exactly as expected, but the phenotype ratios have been changed. What happened was that R was not completely dominant over r and this made it possible to distinguish Rr as pink from RR (Red) and rr (White).
What will be the genotypic ratio in F₂ generation when F₁ (Rr) was self-pollinated?

If a sample has \(n\) observations \(x_1, x_2, \ldots, x_n\) with \(m\) constraints on these values, then the degree of freedom of the sample statistic is:

The area bounded by the curve \(y=x^2\) between \(x=0\) and \(x=\pi\), in the first quadrant is :
