Kenneth Raymond Miller (born July 14, 1948) is an American cell biologist, molecular biologist, and Professor Emeritus of Biology at Brown University. [2] [3] Miller's primary research focus is the structure and function of cell membranes, especially chloroplast thylakoid membranes. [2]
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
The provision of care, by either males or females, is presumed to increase growth rates, quality, and/or survival of young, and hence ultimately increase the inclusive fitness of parents. [ 2 ] [ 3 ] [ 4 ] In a variety of vertebrate species (e.g., about 80% of birds [ 5 ] and about 6% of mammals), [ 6 ] both males and females invest heavily in ...
Lamarck argued, as part of his theory of heredity, that a blacksmith's sons inherit the strong muscles he acquires from his work. [1]Lamarckism, also known as Lamarckian inheritance or neo-Lamarckism, [2] is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime.
Sexual selection is an evolutionary concept that has been used to explain why, in some species, male and female individuals behave differently in selecting mates. In 1930, Ronald Fisher wrote The Genetical Theory of Natural Selection, [3] in which he introduced the modern concept of parental investment, introduced the sexy son hypothesis, and introduced Fisher's principle.
In plants, POC over the allocation of resources to the brood members may affect both brood size (number of seeds matured within a single fruit) and seed size. [3] Concerning brood size, the most economic use of maternal resources is achieved by packing as many seeds as possible in one fruit, i.e., minimizing the cost of packing per seed.

Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration , asexual reproduction , metamorphosis , and the growth and differentiation of stem cells in the adult organism.
