Pertaining to genetic information that will not be passed on to offspring and therefore will not contribute to the gene pool of the species and its diversity. This is usually a result of an organism being unable or unwilling to reproduce.
Genes are the blueprint of our bodies, a blueprint that creates a variety of proteins essential to any organism's survival. Find out in this lesson the various factors that affect growth. ..
This lesson looks at population attributes, regulation, and growth. It also covers population genetics, particularly genetic variations, natural selection, genetic drift, genetic migration, and speciation...
Plants, like animals, produce hormones to regulate plant activities, including growth. They need these hormones to respond well to their environment and to sustain growth, development, and dispersal. Plant biologists recognize five major groups of plant hormones: auxins, gibberellins, ethylene, cytokinins, and abscisic acid. Find out in this guide the importance of each hormone in the life of a plant...
With regard to the population size of a species and what factors may affect them, two factors have been defined. They are the density-dependent factors and the density-independent factors. Find out the differences between the two in this tutorial. Know how these factors affect populations in an ecosystem...
This tutorial elaborates on the physical development of humans, particularly from puberty to adulthood. Read this tutorial to know the specific physical changes that female and male bodies undergo as they turn into adults...
