chromosome complement

A karyotype is the characteristic chromosome complement of a eukaryote species.

More commonly cytochimeras have simple multiple of the normal chromosome complement in the changed layer.

However, the infertile type has a nucleus with a normal, haploid chromosome complement.

It is useful for identifying genetic diseases through the photographic representation of the entire chromosome complement.

Their splitting into two equal longitudinal halves assured each daughter cell got the same chromosome complement.

Most commonly when CPM is found it represents a trisomic cell line in the placenta and a normal diploid chromosome complement in the baby.

Patnaik,AK; Samanta,M; Prasad,R (1981): Chromosome complement and banding patterns in a Pelecaniform bird, Phalacrocorax niger.

Theoretically, X-inactivation should eliminate the differences in gene dosage between affected individuals and individuals with a normal chromosome complement, but in affected individuals the dosage of these non-silenced genes will differ as they escape X-inactivation.

In the strict sense, a chromosome complement having a number of chromosomes other than 46 (in humans) is considered heteroploid while an exact multiple of the haploid chromosome complement is considered euploid.

Trisomic rescue (also known as trisomy rescue or trisomy zygote rescue) a genetic phenomenon in which a fertilized ovum containing three copies of a chromosome loses one of these chromosomes to form a normal, diploid chromosome complement.

In genetic recombination, the double chromosome complement sets, maternal and paternal homologues, pair up, break and recombine to yield oVspring chromosomes the left half of which derives from one parental chromosome, the right half of which derives from the other parental chromosome.
