dimorphism

"dimorphism" 的音标为 [daɪˈmɔːfɪstəm] ，基本翻译为“二态性，异态性”，通常指的是生物在性别、形态、行为等方面的差异。

速记技巧：可以利用词根记忆法来记忆 "dimorphism"，其中 "dimo" 意为 "双，两" ，"morph" 意为 "形状，形态" ，组合在一起就可以理解为生物在两种形态之间的变化或差异。

Dimorphism这个词源于希腊语，意为“两种形式”或“两种表现”。它的词源可以追溯到dimos，意为“两个”或“两部分”，以及morph，意为“形状”或“形式”。

Dimorphism的变化形式主要有名词和形容词。名词如：domorphism（同形现象）、dymorph（双形）等。形容词如：dimorphic（双态的）、dimorphous（两态的）等。

相关单词有：heteromorphism（异形性）、allomorphism（同形反应）、morphogeny（形态发生）、morphology（形态学）、morphogenesis（形态发生）、differentialmorphology（形态差异）、morphostatistics（形态统计学）等。这些单词都与形态变化有关，涵盖了生物学、化学、物理学等多个领域。

dimorphism的常用短语：

1. sexual dimorphism 性别差异

2. phenotypic dimorphism 表型二态性

3. sexual dimorphic traits 性别二态性特征

4. sexual dimorphism in size 大小性别二态性

5. sexual size dimorphism 大小性别二态性

6. morph-sexual dimorphism 形态-性别二态性

7. sexual dimorphism in coloration 颜色性别二态性

英文小作文：

In nature, we see many examples of dimorphism, where one species is noticeably different from another species in appearance, behavior, or adaptations to their environment. This phenomenon is fascinating because it helps us understand how species have evolved over time and how they have adapted to their unique environments.

For instance, we see examples of sexual dimorphism in animals, where males and females differ significantly in size, coloration, or behavior. This is seen in birds, where the males often have brighter colors and more elaborate courtship displays than the females. Similarly, we see phenotypic dimorphism in plants, where different species may have different leaf shapes, colors, or growth habits.

Dimorphism can also be seen in social behaviors, where one group may be dominant over another group, or where one species interacts differently with another species in their social interactions. This can lead to interesting patterns of dominance and subordination among species, which can help us understand how ecosystems function and how species interact with each other.

Overall, dimorphism is a fascinating aspect of biology that helps us understand the diversity of life on Earth and how species have adapted to their unique environments over time.
