How are the different branches of biology dependent on one another?

Nostrana [21]

All the fields of biology share one trait in that they are employed to investigate various aspects of all naturally occurring living things and offer knowledge about their development, reproduction, structure, and demise.

There are several interconnected fields that makeup biology. Evolution, molecular biology, physiology, cell biology, zoology, microbiology, medicine, botany, genetics, marine biology, and ecology are the several subfields of biology.

Biology is the branch of science concerned with examining living things and their biological processes (Greek words, bios – life, logos – study). All facets of the study of living things are covered, including their occurrence, classification, ecology, economic significance, exterior shape, organization, internal structure, nutrition, health, and other bodily functions, as well as their reproduction, life histories, heredity, and origins. The term biology is sometimes substituted with the terms "life sciences" or "biological sciences" since they are more inclusive and multidisciplinary. The "Father of Biology" is Aristotle. Lamarck is credited with coining the term "biology."

The presence of freckles is due to a dominant allele. four percent of the individuals in a particular population lack freckles.

vaieri [72.5K]

Let us assign the recessive allele for freckle to be f and the dominant F. According to the statement, we deduce that ff = 0.04.

The frequency of the recessive f allele is, therefore, is 0.2 (square root of 0.04 ).

Hardy-Weinburg p + q = 1

P + 0.2 = 1; p = 1- 0.2 = 0.8

Therefore using the Hardy-Weinburg equation of a population in equilibrium

P2+2pq+q2=1

Heterozygous individuals are;

2pq = 2*0.8*0.2 = 0.32

This is 32% of the population
