31 de ago. de 2020 · Genetics is a field of biology that studies how traits are passed from parents to their offspring. The passing of traits from parents to offspring is known as heredity, therefore, genetics is the study of heredity. This introduction to genetics takes you through the basic components of genetics such as DNA, genes, chromosomes and genetic ...

Reproductive Barriers – Obstacles that prevent two animals from producing fertile offspring. Binomial Nomenclature – The system of naming individual species with two Latin names, the first related to their genus, the second to their species.
In biology, offspring are the young creation of living organisms. They may be produced by a single organism or, in the case of sexual reproduction, two organisms. Collective offspring may be known as a brood or progeny. In a more general way, 'brood' implies a set of simultaneous offspring, such as the chicks hatched from one clutch of eggs ...
Figure 11.2.3 11.2. 3: Plants have a life cycle that alternates between a multicellular haploid organism and a multicellular diploid organism. In some plants, such as ferns, both the haploid and diploid plant stages are free-living. The diploid plant is called a sporophyte because it produces haploid spores by meiosis.
2 de may. de 2017 · Genetics is the study of genes and inheritance in living organisms. This branch of science has a fascinating history, stretching from the 19th century when scientists began to study how organisms inherited traits from their parents, to the present day when we can read the “source code” of living things letter-by-letter.
Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring. Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.
