Tetraploids (4n) : — Tetraploids originally occurred by freak happenings, the plants' cellular structure changing in such a way as to possess twice the normal number of chromosomes in their make-up. Though tetraploids are often characterized by slower growth and heavier texture, the significance to the naked eye may or may not be apparent. It is also questionable to say that tetraploids are always necessarily associated with desirable features, such as good form and other characteristics we look for. Their main significance lies in their breeding influence. Because of their doubled chromosome number, they assert double the influence that a normal diploid would. Thus, the tetraploid has led to the finest advances in orchid breeding. This is because certain plants of good quality have been discovered to be tetraploids and they have been used in breeding to exert the advantage of their added breeding influence. #phenotype #HealthIndustry #Polyploid #PlantOrganismClassification #tetraploid #triploid #chromosomes #ratio #proportions #punnetSquares #genotypes #phenotypes #ratios #percents #Heterozygous #homozygous #genotypeRatio #phenotypeRatio #basicGenetics #dihybridCross #dihybridCrossShortcut #geneticsBiology #geneticsAmoebaSisters #geneticsCrashCourse #Genetics101 #biologyMajor #biologyCrashCourse #biologyCrashCourseGenetics #mendelsLaws #mendelsLawOfInheritance
