Definition: A thin, membranous sac that forms in the embryos of mammals, birds, and reptiles. It plays a key role in developing the umbilical cord and placenta in mammals.

Example: The allantois plays a crucial role in the development of the embryo by facilitating nutrient and waste exchange.

Definition: A specific version of a gene that is found at a particular place on a chromosome, which can vary among individuals.

Example: Each parent contributes one allele for each gene to their offspring.

Definition: Relating to different forms of a gene that can exist at a specific location on a chromosome.

Example: The allelic variation in the population contributed to the diversity of traits observed.

Definition: A type of gene that can exist in different forms, which can lead to variations in traits among individuals.

Example: The study of allelomorphs helps geneticists understand inheritance patterns.

Definition: Relating to a specific form of a gene that can exist in different versions, which are called alleles.

Example: The allelomorphic variations in the gene pool contribute to the diversity of traits in the population.

Definition: A term used in genetics to describe the presence or inheritance of different forms of a gene, known as alleles, that can result in various traits.

Example: The study of allelomorphism is crucial in understanding genetic inheritance patterns.

Definition: Describing a process where one plant releases chemicals that can affect the growth or development of other plants nearby.

Example: The allelopathic properties of certain plants can inhibit the growth of nearby species.

Definition: A process where one plant species releases chemicals that prevent the growth of another plant species.

Example: The phenomenon of allelopathy can significantly affect plant community dynamics.

Definition: A substance that can cause an allergic reaction in some people, such as pollen, dust, or certain foods.
