Imagine that a rancher has a herd of cattle with brown hides and short horns. all of his cattle are also relatively short in stature. if all of these traits were true breeding, what could you say about the progeny of these cattle? a) it is impossible to determine the traits of such progeny—they will likely demonstrate different hide colors, horn lengths, and heights. b) the progeny of these cattle will have brown, black, white, and spotted hides. c) the progeny of these cattle will have short horns, but a variety of hide colors and heights. d) the progeny of these cattle will be short in stature and have brown hides and short horns. e) since the cattle are true breeding, the progeny of this herd will all be sterile.

The correct answer would be option D.

Explanation:

True breeding is a breeding procedure in which the parents would always produce their progeny with the same phenotype characters as the parents carry. This means for every trait these parents are homozygous so their offspring must show a similar phenotype.

In this case, all cattle are true-breeding which means they homozygous alleles show the progeny will also show similar traits which are short stature with brown hides and short horns.

Thus, the correct answer is option D.

amber has allowed scientists to study dna that has been preserved over millions of years.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
