In natural selection, the population of living entities adapt and change. Naturally, individuals of a population are variable, making them better... View Article
Evolution causes changes in the traits of a species over time, through generations and hence depends upon natural selection. The theory of... View Article
Fossils render evidence for the earliest forms of life. With the help of fossils, Paleontologists have observed the changes found in the... View Article
The speed of evolution is assessed in the genetic variation of a species over time. Accumulation of genetic variations over time produces species... View Article
Organisms who reproduce through asexual means show little to no variation at all. This is because, asexual reproduction involves only a single... View Article
Starfish exhibit asexual mode of reproduction, precisely, fission or autotomy of arms. During fission, the central discs disintegrate into two... View Article
Viruses need a host to reproduce, they cannot reproduce on their own. A host cell is required for this. Virus infects a host cell thereby... View Article
Onions can be grown from bulbs or seeds. Through vegetative propagation, onions can be grown from bulbs. The bulb grows by the growth of the... View Article
Almost all insects reproduce sexually. Some species of insects can also reproduce asexually through parthenogenesis. In this process, eggs of... View Article
Asexual reproduction produces offsprings which are genetically identical to the parent as offsprings are all clones of the original parent.... View Article
Pollen grains are male microgametophytes, of seed plants producing male gametes. In plants, pollen are used to transfer haploid male genetic... View Article
Oxygen is required for Krebs cycle. In the electron transport chain, oxygen is the final acceptor of electrons. The electron transport chain gets... View Article
The Hardy Weinberg Equation can be represented by p2 + q2 + 2pq = 1 For a population to be in Hardy-Weinberg equilibrium or a non-evolving... View Article
Yes, hair color is a polygenic trait. Some other polygenic traits are human skin, eye color. These are polygenic traits because they are... View Article
Georges Cuvier Georges Cuvier is often credited to being the founding father of Paleontology. Paleontology is the study of life on Earth as... View Article
Somatic cells produce non-germline tissues. Somatic mutations are mutations in somatic cells. The mutation cannot be passed through sexual means... View Article
The short answer to it is, yes. Sickle cell disease is a single point mutation, a missense mutation in the beta-haemoglobin gene which converts... View Article
The ultimate source of variation is mutation. Some mutations lead to newer versions of proteins and help the organisms to adapt to changes in the... View Article
A missense mutation is a mistake in the DNA leading a wrong amino acid to be integrated into a protein due to a change. This results in a... View Article
Yes, Translocation Down Syndrome is a type of Down Syndrome which can be inherited from a parent who does not have traits of Down syndrome, there... View Article
