đa bội

Friendly

The Vietnamese word "đa bội" refers to the concept of "polyploid" in English, which is a term used in biology. Here’s a simple breakdown to help you understand it better:

Basic Definition:

• Đa bội (polyploid): This term describes organisms that have more than two complete sets of chromosomes in their cells. For example, while humans are diploid (with two sets of chromosomes), some plants can be triploid (three sets) or tetraploid (four sets).

Usage Instructions:

• "Đa bội" is primarily used in scientific contexts, especially in genetics and botany. You would typically encounter this word in discussions about plant breeding, evolution, and genetic variation.

Example Sentence:

• "Nhiều loại cây trồng, như lúa và ngô, có thể là đa bội, giúp chúng có khả năng thích nghi tốt hơn với môi trường." (Many crops, such as rice and corn, can be polyploid, which helps them adapt better to the environment.)

Advanced Usage:

• In advanced discussions, "đa bội" can be differentiated into subcategories like:
  • Đa bội tự nhiên (natural polyploid): Polyploids that arise naturally through evolutionary processes.
  • Đa bội nhân tạo (artificial polyploid): Polyploids that are induced through human intervention, such as through chemical treatment or hybridization.

Word Variants:

• Đơn bội (haploid): Having one complete set of chromosomes.
• Nhị bội (diploid): Having two complete sets of chromosomes (like humans).
• Tam bội (triploid): Having three complete sets of chromosomes.

Different Meanings:

• While "đa bội" primarily refers to polyploidy in biology, in a broader sense, it can also imply complexity or multiplicity in other contexts, although this usage is less common.

Synonyms:

• In the biological context, there aren’t direct synonyms for "đa bội," but related terms include:
  • Polyploidy (the condition of being polyploid).
  • Chromosome duplication (the process leading to polyploidy).

Summary:

The term "đa bội" is important in understanding genetic diversity and adaptation in organisms, especially in plants. It is a key concept in fields such as botany, genetics, and agriculture.
