👤 whose
Whose work first proved that mammalian chromosome number can vary widely between species?
Quick Answer
Early cytogeneticists established this in the 20th century; mammals can have very different chromosome counts, from the Indian muntjac’s low number to the potato hamster’s high count.
The Full Story
Chromosome research in mammals showed that chromosome number is not fixed across the class. Scientists found striking variation between species, with some mammals having very few chromosomes and others many more. These discoveries were important for genetics, evolution, and breeding studies. The work helped confirm that chromosomes carry hereditary information and can change dramatically during evolution.
Key Facts
1.Mammal chromosome counts vary widely
2.Cytogenetics developed strongly in the 20th century
3.Chromosomes are central to heredity
