Explanation:

All statements are correct.

Chimera in Biology

Recently the scientists have succeeded in producing a live infant chimeric monkey.

• A genetic chimaera is a single organism composed of cells of more than one distinct genotype or genetic makeup.

• Genotype refers to the genetic makeup of an organism which describes an organism's complete set of genes.

• In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism.

• Chimerism can also result from twin or multiple pregnancies evolving into a single foetus or a twin foetus being absorbed into a singleton.

• There is evidence of individuals living with two blood types.

• Microchimerism is a phenomena in which traces of the foetus’s genetic material are observed in mothers’ tissues many years after childbirth, resulting in two different genetic materials in a single person.

Hence option 3rd is correct.
