So we’ll just use “R” and “r” for this example. If the mother AND father are heterozygous, then both of their genotypes are “Rr” if you work out the lumber square or use the foil method, the box would look like this: RR on top left, Rr on top right, Rr on bottom left, and rr on bottom right. So the genetic probabilities, using four as the sum would be 1:2:1
Answer:
True.
Explanation:
The hedgehog gene has the same role in humans and in fruit flies because this gene gives instruction to make proteins that are essential for the growth and development of the body. Genes have the recipes for making of proteins of all type. Genes have the same function in all type of organisms which is to give instructions to the cells for making proteins necessary for the growth, development and survival of that organism.
Hey there!
First when adding fractions, you have to have the same denominator
So, the least common multiple or LCM is 12 because
6, 12
And
4, 8, 12
They both match at 12 so that is the LCM or denominator.
Now since you multiplied 6 * 2 = 12 and 3 * 4 = 12
Multiply the numerator by the same number.
So 1/6 * 2 = 2/12
And
3/4 * 3 = 9/12
<u>Your answer is 11/12</u>
Hope this helps
