mechanism that produces a parallel between ontogeny and phylogeny

Answer 22

heterochrony

Question 23

recapitulation of phylogeny dependent on the physiological functions of heredity

Answer 23

ontogeny

Question 24

evolutionary process in which larval or juvenile features of an ancestral organism are displaced to the adult forms of its descendants

Answer 24

paedomorphosis

Question 25

if the period of growth of the descendant form is stopped prematurely

Answer 25

progenesis

Question 26

if onset of growth is delayed

Answer 26

postdisplacement

Question 27

if the rate of growth is less in the descendant than in the ancestory

Answer 27

neoteny

Question 28

phylogenetic change in which individuals of a species mature past adulthood and take on traits which haven’t seen yet

Answer 28

peramorphosis

if the onset of growth occurs earlier in the descendant than in the ancestor

Answer 30

predisplacement

Question 31

if the growth rate is increased

Answer 31

acceleration

Question 32

the conditon where the two sexes of the same species exhibit different characteristics beyond the differences in their sexual organs

Answer 32

sexual dimorphism
