Just changing the number of units in a fertilized mouse egg cell might be interesting. I think mice or some other rodents only have a few chromosomes which would make it easier still. One might have to extract the chromosomes and add longer telomeres through splicing or the use of telomerase, then readd to the cell. One could check the embryo for telomere number. How are the telomeres' unit numbers added in gamete or fertilized egg cells? Is it as seperate germ cells or in the newly fertilized cell? Are the exact numbers of units to be added well regulated and if so how? Or are germ cells like skin cells in that they will not decrease telomere length?
