11. In a species of cattle, curly hair (C) is dominant over straight hair (c). The value of curly haired cattle is higher than straight haired cattle A rancher wanted to breed a herd of only curly haired cattle. He mated four hybrid curly haired bulls (Cc)with four hybrid curly haired (Cc)cows. If one calf was born to each of the four cows, how many were curly haired? Do) 3 Da) 1 Din) 4 4) 2

To determine how many of the calves will have curly hair, we need to consider the genetic combinations that can result from mating two hybrid curly-haired cattle (Cc).The possible combinations of alleles from the mating of two Cc individuals are:1. CC (curly-haired)2. Cc (curly-haired)3. cC (curly-haired)4. cc (straight-haired)The Punnett square for this mating would look like this:| | C | c ||-------|-----|-----|| **C** | CC | Cc || **c** | Cc | cc |From the Punnett square, we see that there are:- 1 CC (curly-haired)- 2 Cc (curly-haired)- 1 cc (straight-haired)So, the probability of a calf being curly-haired (CC or Cc) is 3 out of 4, or 75%.Since each cow can produce one calf, and there are four cows, the number of calves expected to be curly-haired is: Therefore, the number of calves that were curly-haired is: So, the correct answer is:Do) 3
