PROBLEM 23-2 Differentiate between isolecithal, telolecithal, and centrolecithal
eggs . Which organisms are characteristic of each? Solution : The eggs of
different animals vary greatly in the amount and distribution of the yolk they
contain.

Herpetology: An Introductory Biology of Amphibians and Reptiles
Mammals have isolecithal ova, but amphibians and reptiles do not. These two
clades have mesolecithal (moderately yolked) and macrolecithal (heavily yolked)
ova, respectively (Table 2.1); the ova of most direct-developing amphibians tend
...

Instant Notes Animal Biology
Holoblastic cleavage in the isolecithal egg of amphioxus is radial, with the initial
three cleavage planes mutually at right angles to each other, to give eight
blastomeres of roughly equal size. The embryo can be bisected along any
vertical ...
Isolecithal. Egg. The main processes involved in the conversion of monoblastic
blastula into a diploblastic and stratified gastrula. are invagination, involution and
a kind of epibolic morphogenetic movements of different blastomeres with the ...

Isolecithal. or. Microlecithal. Egg. In microlecithal egg with holoblastic cleavage,
the blastomeres at the end of the cleavage are not of exactly equal size due to
slight yolk inhibition of vegetal cells. These cells arrange themselves into a
simple ...

Early Embryology of the Chick, Fourth Edition
An ovum with such a yolk distribution is termed isolecithal (homolecithal) . An
isolecithal egg undergoes a type of cleavage which is essentially an unmodified
mitosis. The yolk is not sufficient in amount, nor sufficiently localized to alter the ...

... portions of the egg; yolk is partitioned into the cells as they are formed by
cleavage. In the case of isolecithal eggs the entire egg divides and produces a
number of approximately equal cells. Such cleavage is said to be holoblastic and
equal ...

Whereas the cells of relatively yolk-free, isolecithal embryos of a "primitive"
animal with direct development, such as the cephalochordate Amphioxus (now
Branchiostoma), produce a spherical blastula and early gastrula, those of a
highly yolky ...

Consequently, the telolecithal condition is the plesiomorphic state in reptiles (
witness the development of isolecithal eggs (with minimal and evenly distributed
yolk) as an apomorphy among individual lizards). Isolecithal eggs are only
possible ...
