What is polymorphism in zoology? Morphism: In zoology, words that contain the term "morphism" are used to describe the bodies of animals in a species, but they do not always apply to the same type of bodily characteristics. Some other examples of words with this component are dimorphism and...
Competition is the process of opposing another individual for the chance to win a status, opportunity, etc. It is a major driving factor in human as well as animal life.Answer and Explanation: A male-male competition is when two males of a species are vying for a mating opportunity with ...
A scheme simple enough, isn’t it? As for breeding – it is quite simple. The gender dimorphism of paragurs is really amazing thing. The fact is that all symbiotic paragurs are females. Males are at least twenty-times smaller and hve a sole purpose – breeding. They are very mobile ...
What evolutionary purpose these variations serve remains a mystery. But one thing is clear: sex chromosomes don’t hold the key to defining biological sex. 4. Why Genes Can’t Definitively Determine Sex Just like sex chromosomes, the genes responsible for sex determination and development are far...
USA; 4Department of Obstetrics and Gynecology, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA, USA The inclusion of sex as a biological variable in research is absolutely essential for improving our understanding of disease mechanisms contributing to risk and resilience...
average, tend to be more attracted to men who havea relatively narrow waist, a V-shaped torso, and broad shoulders. Women also tend to be more attracted to men who are taller than they are, and display a high degree of facial symmetry, as well as relatively masculine facial dimorphism. ...
while females have two X chromosomes. Thus, sex chromosome constitution also differs between the sexes. Due to this complexity, determining genetic and downstream biological influences on sexual dimorphism in humans is challenging. Sex chromosome aneuploidies, such as Turner syndrome (X0) and Klinefelte...
What is sexual dimorphism? What is the evolutionary benefit of genders? How is a gender of a fossil determined? What are the gender differences in brain development and structure? Are there species that aren't gender binary? How is sex determined in humans?
