(anatomy) the muscular body partition that separates the chest and abdomen

a sack of tissue that is attached to the large intestine and is surgically removed if infected

relating to the intestines, which are part of the digestive system responsible for absorbing nutrients and removing waste from the body

the front part of the brain involved in higher cognition and executive functions

(anatomy) an abdominal organ that controls the quality of the blood cells

the hard white external layer that covers the crown of a tooth

(anatomy) a bone of the shoulder girdle that connects the breastbone to the shoulder bone

(anatomy) a spiral cavity in the inner ear that contains sensory organs which send nerve signals to the brain in response to vibrations

the first part of the large intestine, located in the lower right abdomen

the upper part of the human body, excluding the arms and the head

any blood vessel, carrying the blood to different organs of body from the heart

a place in the body where two bones meet, enabling one of them to bend or move around

the row of small bones that are joined together down the center of the back of the body

(anatomy) a system of interconnected organs or tissues that perform a particular task in the body

relating to the heart or the network of blood vessels encircling it

a small, butterfly-shaped gland located at the base of the neck, responsible for producing hormones that regulate metabolism and other bodily functions

the bone that forms the ankle joint with the tibia and fibula, supporting the body's weight and allowing movement of the foot

a sac-like organ inside the body where urine is stored before being passed

relating to processes and behaviors involved in the creation of offspring within a species

relating to any of the five senses

relating to the sense of touch or the ability to perceive objects by touch

(anatomy) connected with the sensory part of the eye that sends signals to the brain, called retina

related to the ability of hearing

relating to sight or vision

a very small threadlike structure in a living organism that carries the genes and genetic information

the complete set of genetic material of any living thing

the genetic makeup of an organism, determined by the combination of genes inherited from its parents

the observable physical and behavioral characteristics of an organism, resulting from the interaction of its genotype (genetic makeup) with the environment

one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome

(of a gene or trait) showing its specific appearance only when an individual inherits it from both parents

(of genes) causing a person to inherit a particular physical feature, even if it is only present in one parent's genome

the process by which information from a gene is used to synthesize functional gene products, such as proteins, which can influence an organism's traits

to alter or change the genetic makeup of an organism through genetic engineering techniques

(biology) a change in the structure of the genes of an individual that causes them to develop different physical features

to receive traits or attributes from a previous generation through genetic inheritance

the passing down of traits from one generation to another within a family

a person from whom other offsprings are descended

(of an organism) having genetic material from another species that has been artificially introduced into its genome

a specialist in or student of the branch of biology that deals with how individual features and different characteristics are passed through genes

a visual display of an individual's chromosomes, used for genetic analysis and identifying abnormalities

the practice of improving the genetic quality of a human population through selective breeding and other methods

a genetic condition in which an individual has three copies of a chromosome instead of the usual two

the region of a chromosome where the two sister chromatids are joined and where the spindle fibers attach during cell division

a DNA sequence that has the same order of nucleotides on each side of the complementary DNA strands

the branch of genetics that studies the structure and function of chromosomes using microscopic and molecular techniques

any chromosome that is not involved in determining sex, present in pairs in both males and females, and carrying most of an individual's genetic information

the process of introducing foreign DNA or RNA into eukaryotic cells to study gene function or manipulate gene expression

in a manner that is related to genetics or genes

a cell or organism containing a single set of unpaired chromosomes, typically denoted as n, representing half the genetic material of a diploid cell

a family of transcription factors that play important roles in regulating gene expression in response to various stimuli
