All of about is the answer
Answer:
The correct answer is C) gene flow
Explanation:
The biological species concept defines what is a species. It says that a species is a group of individuals in a population that interbreed with each other. So there should be gene flow between the members of the population to come under species.
Appearance does not define that two individual are of same species because even different species can look same for example Western meadowlarks and eastern meadowlarks looks identical to each other but they do not interbreed so there is no gene flow between them so they are not same species.
Therefore the primary criteria for determining species boundaries is gene flow.
Answer:
Let's consider that the allele 'B' is for Black hair colour and it is dominant. Let's consider that the allele for red hair colour is b.
Let's consider the allele for lacking horns or polles is 'P' and it is dominant. The allele for having horns is 'p' and it is recessive.
When two heterozygous black, lacking horns (BbPp) are crossed, the results will have the probability of 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned organisms.
Answer:
Until the past decade, scientists, research institutions, and government agencies relied solely on a system of self-regulation based on shared ethical principles and generally accepted research practices to ensure integrity in the research process. Among the very basic principles that guide scientists, as well as many other scholars, are those expressed as respect for the integrity of knowledge, collegiality, honesty, objectivity, and openness. These principles are at work in the fundamental elements of the scientific method, such as formulating a hypothesis, designing an experiment to test the hypothesis, and collecting and interpreting data. In addition, more particular principles characteristic of specific scientific disciplines influence the methods of observation; the acquisition, storage, management, and sharing of data; the communication of scientific knowledge and information; and the training of younger scientists.1 How these principles are applied varies considerably among the several scientific disciplines, different research orgrecently, a few research institutions have developed guidelines for the conduct of reserch
