Explanation:
If a somatic human cell is about to divide, then it has 92 chromatids. this is because there are 23 pairs of homologues chromosomes in a cell, one is given by both parents. when a cell divides my mitosis, the pairs separate into 46 chromatids, each one that is replicated which gives you 92 chromatids.
Answer:
As quantitative data collection methods are often based on mathematical calculations, the data obtained that way is usually seen as more objective and reliable than qualitative. Some of the most common quantitative data collection techniques include surveys and questionnaires (with closed-ended questions).
Explanation:
Answer:
The probability that both will be Rh-negative out of 99% Rh-positive is 0.01 x 0.01 = 0.0001.
Explanation:
The population contain 99℅ of Rh-positive. This represent almost all of the people.
However, there is still 1℅ chance of having an individual of Rh-negative.
Both of them will have the probability of 1℅ of having Rh-negative(0.01).
Therefore, Pr(Rh-negative AND Rh-negative) = 0.01 x 0.01. The result is approximately equals zero.
The both parents having Rh-negative, will have a dominant Rh-negative blood passed to their children, only recessive Rh-positive of 25℅ chance.
Since the chance of Rh-negative blood passed to their children is 75℅, it is inevitable that their children will be Rh-negative
