androgeny

Thân thiện

A scientist observes androgeny in a laboratory culture.

Definition

Noun: 1. A specific type of male parthenogenesis: Androgeny refers to a biological process in which an embryo develops containing only paternal chromosomes. This occurs due to the failure of the egg nucleus to participate in fertilization, resulting in offspring with a genetic makeup derived solely from the male parent.

Usage Notes

• "Androgeny" is a highly specialized scientific term used primarily in the fields of developmental biology, genetics, and zoology.
• It describes a rare reproductive phenomenon and is not a common term in everyday language.
• The term is often discussed in contrast to other reproductive modes like gynogenesis (where the embryo contains only maternal chromosomes) or typical sexual reproduction.

Examples

• Scientific Context:
  • The study documented a case of androgeny in a fish species, where the offspring were genetically identical to the father.
  • Researchers are investigating the mechanisms that lead to androgeny, specifically the inactivation of the egg nucleus.

Advanced Usage

• The concept is central to discussions about uniparental reproduction and the developmental potential of paternal genomes.
• It is sometimes referenced in theoretical discussions of evolution and reproductive strategies.

Variants and Related Words

• Androgenesis (noun): This is a more commonly used synonym for "androgeny" in scientific literature. Both terms are often used interchangeably to describe the same process.
• Parthenogenesis (noun): A general term for reproduction without fertilization. Androgeny is a specific type of male parthenogenesis.
• Gynogenesis (noun): The complementary process to androgeny, where the embryo contains only maternal chromosomes, but sperm is required to trigger development.

Synonyms

• Androgenesis
• Male parthenogenesis

Antonyms

• Gynogenesis
• Sexual reproduction
