What does the genetic term mosaic mean?
In genetics, a mosaic refers to an organism that has cells with different genetic makeup due to mutations occurring after fertilization. This can result in patches of tissue with varying genetic characteristics within the same individual. Mosaicism can arise during embryonic development and is a common phenomenon in many organisms.
What does the term potency refer to when talking about stem cells?
Potency in stem cells refers to the ability of a stem cell to differentiate into different cell types. Stem cells can be classified as totipotent, pluripotent, multipotent, or unipotent based on their differentiation potential. Totipotent stem cells can develop into any cell type, whereas unipotent stem cells can only differentiate into one specific cell type.
The mosaic effect in female cats can be observed in what skin color hair color distribution of fat cells distribution of sweat glands or all of these?
The mosaic effect in female cats can be observed in the distribution of coat colors. This is due to a phenomenon called X-inactivation, where one X chromosome is randomly inactivated in each cell during development, leading to different patches of different colors on the same cat. It is not related to the distribution of fat cells or sweat glands.
What is the difference between potencies of stem cells?
To understand potency we jave to know that the Potency of a stem cell relates to its ability to differentiate. Currently the most potent cell lines are: • Totipotent stem cells that can differentiate into embryonic and extraembryonic cell types. • Pluripotent cells can differentiate into nearly all cells. • Multipotent cells can differentiate into a number of cells, but only those of a closely related family of cells • Oligopotent cells can differentiate into a few cell types like myeloid stem cells • Unipotent cells can only produce one cell type, themselves. source:http://stemcellthailand.org/differentiation/
What is described by the fluid mosaic model?
The fluid mosaic model describes the structure of the plasma membrane in cells. It states that the membrane is composed of a fluid bilayer of phospholipid molecules in which various proteins are embedded or attached, resembling a mosaic pattern. This model emphasizes the dynamic and flexible nature of the membrane.

Why is it Mosaic?
It is called a mosaic when an individual has different genome on different cells. For example a person can have trisomy 21 (down syndrome) in some specific tissue and be completely normal on other tissue.
What type of Down syndrome is 'Mosaic'?
its where some cells are "down syndrome" cells and some are "typical" cells. meaning some cells have three sets of the 21st chromosome and some have the normal 2 sets.

Totipotent stem cells can develop into any cell type, whereas unipotent stem cells can only differentiate into one specific cell type.
What is a determinate cleavage?
Determinate cleavage is a type of cleavage found in early embryonic development where the fate of each cell is fixed and determined early on. As cells divide, they become committed to specific developmental pathways, leading to the formation of distinct tissues and organs. This type of cleavage occurs in organisms with mosaic development.

What period of human development are cells changing?
Embryonic phase is the period of human development. This is when the cells change.

It states that the membrane is composed of a fluid bilayer of phospholipid molecules in which various proteins are embedded or attached, resembling a mosaic pattern. This model emphasizes the dynamic and flexible nature of the membrane.
The mosaic effect in human females can be observed in?
the random inactivation of one X chromosome in each cell during early embryonic development, resulting in a patchwork pattern of gene expression. This phenomenon, known as lyonization, leads to the presence of cells with different X chromosomes activated in a female individual, contributing to the mosaic effect. It can be observed in various tissues and organs throughout the body.
Are zygotes diploid cells in the early stages of development?
Yes, zygotes are diploid cells in the early stages of development.
