RSSDevelopmental biology
Developmental biology is the
study of the process by
which organisms grow and
develop. Modern
developmental biology
studies the genetic control
of cell growth,
differentiation and

Somatic cell
A somatic cell is generally
taken to mean any cell
forming the body of an
organism. Somatic cells, by
definition, are not germline
cells. In mammals, germline
cells are the sperm and ova
(also known as "gametes")

Mammalian embryogenesis
Mammalian embryogenesis is
the process of cell division
and cellular differentiation
which leads to the
development of a mammalian
embryo. A mammal develops
from a single cell called a

Embryo
In organisms that reproduce
sexually, once a sperm
fertilizes an egg cell, the
result is a cell called the
zygote that has all the DNA
of two parents. In plants,
animals, and some protists,
the zygote will begin to

Germ layer
A germ layer is a collection of cells, formed during animal embryogenesis. Germ layers are only really pronounced in the vertebrates. However, all animals more complex than sponges (eumetazoans and ... > more -
Chromosomal crossover
Homologous recombination is the process by which two chromosomes, paired up during prophase 1 of meiosis, exchange some distal portion of their DNA. Crossover occurs when two chromosomes, normally ... > more -
Morphogenesis
Morphogenesis is one of three fundamental aspects of developmental biology along with the control of cell growth and cellular differentiation. Morphogenesis is concerned with the shapes of tissues, ... > more -
Human biology
Human biology is an academic field of biology which focuses on humans; it is closely related to medicine, primate biology, and a number of other fields. A human being is a multicellular eukaryote ... > more -
Organogenesis
In animal development, organogenesis is the process by which the ectoderm, endoderm, and mesoderm develop into the internal organs of the organism. The germ layers in organogenesis differ by three ... > more -

Fertilisation
Fertilisation, also spelt fertilization (also known as conception, fecundation and syngamy), is fusion of gametes to form a new organism of the same species. In animals, the process involves a sperm ... > more -

Biological tissue is a collection of interconnected cells that perform a similar function within an organism. The study of tissue is known as histology, or, in connection with disease, ... > more -
Genetic recombination
Genetic recombination is the transmission-genetic process by which the combinations of alleles observed at different loci in two parental individuals become shuffled in offspring individuals. In ... > more
