Differences of Sexual dimorphic behavior in mammal
Sexual dimorphism refers to a phenotypic difference shown by females and males within the same species. This means that there are those very specific but obvious differences between male and the female.
The major phenotypic difference that is obvious is presence or absence of reproductive organ. However, other differences behavior, secondary sex characteristics, ornamentation, and size are still present.
Sexual dimorphic behaviors in mammals are portrayed in various ways. First, is in the body composition. Animals with large body size tend to suppress the smaller ones when they are competing for males. More so, this applies to males.
Although, the smaller sized animals have the same capabilities and organs they are more disadvantaged by the body size. However, competing for mating partners they are suppressed by the masculine sized males. Generally, mating is not determined by the body size.
Naturally, in most instances, females are larger than males in mammals. Females unlike males reproduce more young ones to continue the generation. Unlike the mammals, the size of the sperm is too microscopic and it’s for fertilization purpose only.
In addition, the size of the females is largely contributed by storage of fat to provide the female with the required energy necessary for reproduction.
