Answer:
49.14%
Explanation:
The frequency of the heterozygous individuals in the population is therefore: 64/400 = 0.32
Using the Hardy Weingburg equation of a population is equilibrium = p2 + 2pq + q2 = 1
q2 = 0.32; Therefore q = 0.5657 –> alellic frequencies
If p + q = 1; Then p 1 – q = 1 – 0.5657 = 0.4343
Heterozygous individuals are represented by 2pq = 2 * 0.4343 * 0.5657 = 0.4914
0.4914 * 100 = 49.14% of the population which translates to 0.4914 * 400 = 196.56 (197) individuals
Ionic bonds <span>are the type of bonds where there is </span>transfer<span> of electrons from one atom to another. The electrons are removed and from one atom and attached to another. A good example is salt which is composed of sodium and chlorine. Sodium readily loses one of its electrons and chlorine readily accepts it. Before losing the electron, sodium has a positive charge, but then becomes negatively charged after giving up the electron. Chlorine has a positive charge before gaining the electron but becomes negatively charged after gaining the electron. These opposite charges between sodium and chlorine attract the two elements together to form the ionic bond.</span>
Answer:
The correct answers are A and B.
Explanation:
Pleiotropy is defined as "when a single gene affects two or more phenotypic characteristic of an organism.". Phenotypic refers to the traits that can be physically observed or measured in an organism, for example height, hair color etc. So the examples of pleiotropy in the given options are in A and B which describe situations where one gene affects two or more phenotypic traits.
I hope this answer helps.
Answer:
After being hunted almost to extinction, the humpback whale population has rebounded dramatically. Rapidly melting Antarctica ice poses a threat to coastal cities, but there is at least one species that is benefiting: Humpback whales are flourishing these days, due to an abundance of krill.
Pre-hunting population size may have been as many as 200,000-300,000 whales. They were estimated to number around 2,300 in 1998 and to be increasing between 2.4-8.4% per year. The IWC is undertaking an assessment of Antarctic blue whales at present.
