Final answer:
Pubertal growth occurs at Tanner Stage III - IV in both females and males, with this phase being characterized by accelerated growth in height and the development of secondary sexual characteristics.
Step-by-step explanation:
Pubertal growth occurs at Tanner Stage III - IV in both females and males. During these stages, significant changes occur in the physical development of adolescents.
In females, puberty typically starts between the ages of 9 and 10 with the development of breast tissue and pubic hair. The adolescent growth spurt (AGS) kicks in around ages 9 to 11, where girls can experience significant height increases. In males, puberty generally begins later, between ages 11 and 12, first with the growth of the testes, then pubic and other body hair.
The male growth spurt happens toward the end of puberty, approximately from age 11 to 13, with potential height increases of up to 4 inches per year. Both sexes will see their most rapid pubertal growth in Tanner Stage III to IV, which is a mid-puberty phase characterized by accelerated growth in height and development of secondary sexual characteristics.
