Answer:
0
Explanation:
This question involves a single gene coding for wool color in sheeps. The allele for white wool (TT) is dominant over the allele for spotted wool (tt). This means that a sheep with an heterozygous genotype (Tt) will be white-wooled.
In this cross, 10 purebred white wool sheep (TT) are crossed with 10 spotted wool sheep (tt). This will give rise to all offsprings with heterozygous genotype: Tt (see attached image for punnet square). Since, white wool (T) is dominant, all the offsprings will have a white wool and none i.e. 0 will have a spotted wool.

Well first i just wanna say that life on mars has been discovered,not little green men but Bactria found on the surface and small traces of water have been found as well. some forms of life need little water to survive (like bacteria) but they still need water so yes there is water on mars the question is will we find it.
Answer: 5
Explanation:
Since 1 out of 200 people carry the defective gene that causes inherited colon cancer.
In a sample of 1000 individuals, we say
1 = 200
y = 1000
cross multiply
y x 200 = 1000 x 1
200y = 1000
y = 1000/200
y = 5
Thus, in a sample of 1000 individuals, approximately 5 will be carriers
The answer is A, Truth
