Imagine that a rancher has a herd of cattle with brown hides and short horns. All of his cattle are also relatively short in sta
ture. 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.
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.
