Click to see Hint ⬇
DNA carries genetic instructions for living organisms.
Click to see Answer ⬇
Genetic information storage - DNA, or deoxyribonucleic acid, is a molecule that carries most of the genetic instructions used in the growth, development, functioning, and reproduction of all known living organisms and many viruses.

Question 5:

What is the scientific term for an organism composed of cells from different zygotes?

The term is also used in mythology.
Click to see Answer ⬇
Chimera - A chimera is an organism containing two or more populations of genetically distinct cells that originated from different zygotes involved in sexual reproduction.

Question 6:

Which of the following is an example of a chimera in the animal kingdom?

Click to see Hint ⬇
Look for animals with distinct physical features.
Click to see Answer ⬇
A cat with two different colored eyes - A cat with two different colored eyes is often considered a chimera because it is the result of two populations of cells with different genotypes.

Question 7:

In genetics, what does 'mosaic' refer to?

Click to see Hint ⬇
Think about genetic variation and different cell populations.
Click to see Answer ⬇
An organism composed of cells from different zygotes - In genetics, a mosaic refers to an organism that contains two or more populations of cells with different genotypes due to genetic mutation or chimerism.

Question 8:

What is a human chimera?

Click to see Hint ⬇
Think about the genetic makeup of a human chimera.
Click to see Answer ⬇
An organism composed of cells from different zygotes - A human chimera is formed when two fertilized eggs or early embryos fuse together to form a single organism with two sets of DNA.

Question 9:

Which animal is not a natural chimera?

Click to see Hint ⬇
Consider the genetic composition of the animals.
Click to see Answer ⬇
Mule - Mules are not chimeras but rather hybrids, as they are the offspring of a male donkey and a female horse. Chimeras, on the other hand, are organisms composed of cells from different zygotes.

Question 10:

Which of the following is a method used to create chimeras in scientific research?

Click to see Hint ⬇
This method involves the transfer of cell nuclei.
Click to see Answer ⬇
Somatic cell nuclear transfer - Somatic cell nuclear transfer involves transferring the nucleus of a donor somatic cell into an enucleated host egg cell, resulting in the creation of chimeras for research purposes.

Question 11:

Which of the following is a natural plant chimera?

Click to see Hint ⬇
Consider fruits with diverse genetic components.
Click to see Answer ⬇
Citrus fruit - Citrus fruit, including oranges and lemons, are natural plant chimeras, displaying genetic variation in their tissues due to their origin from a fusion of multiple embryos.

Question 12:

What is a human tetragametic chimera?

Click to see Hint ⬇
This condition involves genetic variation within an individual.
Click to see Answer ⬇
An individual with two different sets of DNA - Human tetragametic chimeras possess two different sets of DNA, typically due to the fusion of multiple embryos in early development, resulting in genetic variation within their body.

Question 13:

Which of the following is not a characteristic of a genetic chimera?

Click to see Hint ⬇
Consider the origin of genetic variation within chimeras.
Click to see Answer ⬇
Inherited from both parents - Genetic chimeras do not inherit their chimerism from both parents but instead exhibit genetic variation within tissues due to the fusion of multiple embryos or genetic mutations during development.

Question 14:

In genetics, what is the term for an organism composed of cells from different zygotes?

Click to see Hint ⬇
Consider the term related to genetic diversity within an organism.
Click to see Answer ⬇
Mosaic - In genetics, a mosaic refers to an organism composed of cells from different zygotes, leading to genetic diversity within the individual.

Question 15:

Which of the following animals is a genetic chimera?

Click to see Hint ⬇
Consider animals commonly used in genetic research.
Click to see Answer ⬇
Zebrafish - Zebrafish are frequently used in genetic research to create chimeras due to their regenerative abilities, making them valuable for studying tissue regeneration and genetic modifications.
