Carrying capacity can be defined as a species' average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. If these needs are not met, the population will decrease until the resource rebounds.The logistic population growth occurs when the growth rate of decreases as the population reaches the carrying capacity. The carrying capacity is the maximum number of individuals in a population that the environment can support.In ecological terms, carrying capacity is defined as the maximum number of a species that can sustainably live in a given area. In other words, a population's carrying capacity is the size at which a population can no longer grow due to lack of supporting resources.12-Dec-2013
Walter Sutton discovered that chromosomes are the basis of heredity and this explained the segregation of alleles in Mendel's law of segregation. Basically alleles and chromosomes in Mendel's explanation are the same thing.
