They are called “sister chromatids”
A model organism is a species that has been widely studied to understand a particular biological phenomena, normally used because they are easy to breed and maintain in a laboratory setting and has certain experimental advantage.
The criteria that Thomas hunt Morgan was looking for include; the model organism should be small in size, easy to keep in the laboratory and also able to produce large number of off springs in a short time.
Anaerobic is the physiological process occurrence where muscle cells which amount to the gradual onset of muscle fatigue.
Fatigue muscle is the intense or repeated use of muscle which leads to the performance decline. Muscle fatigue mechanism appears in the involvement of calcium leakage. The physiological factors like maximum rate of oxygen uptake determine maximum intensity exercise.
D. TT x tt. When using a punnett square and substituting with the different genotypes, all of them will be Tt. And since T is the dominant trait, the offspring will be very tall.
