Displaying two separate growth forms. diploid cell( dip-loyd) [Gk. di, double, two + ploion, vessel] A cell containing two sets of chromosomes (2n), one set inherited from each parent.

Having two different distinct forms of individuals within the same species or two different distinct forms of parts within the same organism. For plants, it could refer to different leaf types, flowers, etc. For animals, it could refer to different colouring, sizes, features, etc. Sexual dimorphism is a common case, where the two sexes have different shapes, sizes, etc. from each other.

occurrence of two forms, distinct in color or other characteristic, among animals of the same species.

differences in primary and secondary sexual characteristics.

A polymorphism involving only two forms.

the occurrence of two types of individuals in the same species, distinct in coloring, size, etc. Sexual dimorphism is differences between sexes of the same species

A condition where a population has two distinct physical forms (morphs). In sexual dimorphism, secondary sexual characteristics are markedly different (e.g., size, color, and behavior).

the existence of distinct genetically determined forms of the same species, such as distinct male and female forms or distinct young and mature forms (Morris 1992).

existence in two forms

(chemistry) the property of certain substances that enables them to exist in two distinct crystalline forms

(biology) the existence of two forms of individual within the same animal species (independent of sex differences)

Biological division of structure in a species, such as for sexual reproduction.

The existence two distinct forms of a single species that differ in one or more characteristics, such as coloration, size, or shape.

difference in morphology between members of the same species; sexual dimorphism is a difference between the sexes, dichromatism is a color difference between members of the same sex

Some ammonite species show dimorphism, with two distinct forms being present, known as dimorphs. Commonly the main distinction is size, but they may also have different ornamentation on the shell or additional strucrures such as lappets. Sexual dimorphism is common among those animal species in which the males and females have radically different roles. Among ammonites many species show strong dimorphism (see macroconch and microconch below).

An occurance of an organism in two forms. Sexual dimorphism refers to males and females. Dimorphism may occur in, for example, body form or colour.

the existence of two distinct forms; sexual dimorphism refers to differences between sexes (size, color, etc.)

having two distinct forms; males and females of the same species looking different The red male and brown female cardinals are an example of dimorphism.

The presence of two distinct forms within a species

The occurrence of two distinct forms of structure, size, coloring, or other characteristic in a single species. "Sexual dimorphism" occurs where dimorphism exists between the male and female.

Any of the various differences between individuals of the same species; like color and size. Often sex-related differences.

Two different forms of the same species. Can be concurrent of seasonal forms.

difference between males and females

A "polymorphism" including only two forms.

The property of a group having two different forms as determined by characteristics such as sex, size or coloration.

The existence of two distinct forms of an organism or organ, e.g. winged and wingless generations in the life of aphids, winged and wingless seeds produced from the same flower.

Two different forms of traits. Sexual dimorphism: traits differ between sexes.

Existence of two morphologically different forms in one organism. ( 15)

having two different forms, usually according to size and colour.

Dimorphism means having two forms. It usually means that an organism has two different types, for example, males and females of some species look different, and are said to be sexually dimorphic.
