Flashcards
Fertilization
Fertilization
The union of a sperm and an ovum, leading to the formation of a zygote.
Gametes
Gametes
Specialized sex cells (sperm in males, ovum in females) used in sexual reproduction.
Gamete Chromosome Number
Gamete Chromosome Number
Cells containing half the number of chromosomes (23) found in somatic cells, produced through meiosis.
Genetic Recombination (Zygote)
Genetic Recombination (Zygote)
The merging of genetic material from sperm and ovum into a single cell, creating a new unique set of chromosomes.

Sexual Reproduction
- During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization, where a sperm cell from the male fertilizes an egg cell from the female.
Gametes
- Specialized reproductive cells, responsible for carrying genetic information, are called gametes.
Chromosomes in Gametes
- Gamete cells contain half the number of chromosomes, specifically 23, which is a haploid number (n).
Genetic Recombination
- Genetic recombination occurs in the zygote, during the process of fertilization, where the genetic material from both parents combines to create a unique individual.
Development Process
- The defined development process, from zygote to fully formed organism, is known as embryogenesis.
