Answer:
The correct answer would be 1/32
Explanation:
Mary and Justin can have affected child only when both of them are carriers that is, both of them should be Gg.
The probability of Justin's father to be a carrier is 2/4 or 1/2 [1 GG: 2Gg: 1gg].
Similarly, the probability of Jean to be a carrier would be 1/2.
Thus, the probability of Justin and his father to be a carrier would be equal to 1/2*1/2 ⇒ 1/4.
The probability of Mary to be a carrier = 1/2.
So, the probability of Mary and Justin to be the carrier of the disease would be 1/2*1/4 = 1/8.
Now, the probability of having an affected child would be 1/4 as it is a recessive disorder.
So, the probability of Mary and Justin to have an affected child = 1/4 * 1/8 ⇒ 1/32
The answer to this is B. Topaz
Answer:
- Determine what information is required to collect
- Determine the methodology used for data collection
- Determine the methodology used for analyzing data
Explanation:
Data collection is the process of obtaining and measuring information on a variable of interest, which is used to answer questions about a particular issue and to obtain conclusions by the evaluation of the outcomes. Data collection represents an important issue from a broad spectrum ranging from social sciences to physical/natural sciences, as well as in business structures. For example, in an international company, such data collection enables to save money by building customer's databases that help to reduce marketing efforts. Methodologies for data collection include observational procedures, interviews, questionnaires and group discussions.
Answer:
The ancestors of mammals diverged from ancient synapsids (reptiles).
Explanation:
The mammals have known to be evolved from a group of reptiles. These group of reptiles were known as synapsids. In fact, some scientists consider mammals as the only living synapsids. The close relativity between reptiles and mammals can hence be seen because they have common ancestors. The synapsids were known to inhabit the earth during the Permian Period.
The scientists, however, do not know from which reptiles exactly did the first mammals grow.
