How should the members of a sample be chosen

Biology
1 answer:
azamat3 years ago
3 0

Answer: They must be randomly chosen, meaning that each member of the larger population has an equal chance of being chosen. They must be large enough so as not to skew the results. The optimal size of the sample group depends on the precise degree of confidence required for making an inference. Simple random sampling is the basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population). Each individual is chosen entirely by chance and each member of the population has an equal chance of being included in the sample.

Hope this helps... Stay safe and have a great day/night!!! :D

bulgar [2K]

Answer:

Inbreeding leaves animals susceptible to genetic disease, and populations to reduced fitness. This family of three would not be able to sustain a population given their a) group dynamics and b) genetic variation

Explanation:

In small populations, the variation in genetic material is likely to be low. The consequence of this is that there is increased homozygosity. That means less members of the population carry two different alleles of a gene for any given trait. This increases the chance of the appearance of recessive traits, which could be disease causing or otherwise reduce fitness.

With only three related individuals left, the chances of generating a new and thriving population with the limited genetic material is almost non existent, especially considering the animals are a male, female and their pup
