No , it is caused by a single gene mutation .
Euploid organisms have a chromosome number that is an exact multiple of the haploid number (Euploid organisms may however, exhibit either an increase or a decrease in the chromosome number). Aneuploid organisms however, have altered genomes - they either lack chromosomes or have extra ones.
Guevodoces have the usual XY male chromosomes. The apparent lack of male genitalia at birth is due to a hormonal deficiency that causes a reduced response to testosterone during fetal sexual development. As a result, the baby boy has small and ambiguous genitalia until sex hormones surge at puberty, causing the external genitalia to develop.
No, genetic diversity is not solely due to genes on the sex chromosomes. It is influenced by variation in the entire genome, including genes on autosomes and mitochondrial DNA. Genetic diversity also arises from mutations, gene flow, and genetic recombination during meiosis.
Althouh hibiscus is a flowering plant, it rarely forms seed due genetic dis-order. Triploidy provides good number of attractive flowers but viable gametes are lacking due to lack of pairing of homologous chromosomes during meiosis.
Gametes have an odd number of chromosomes due to the process of meiosis, where the number of chromosomes is halved. This allows for the fusion of gametes during fertilization to produce offspring with the correct number of chromosomes.
Neither. Breast cancer is the over growth of cells due to hormones or genetics.
No, the Huntington's disease is inherited from either the mother or father. It's genes not a lack of chromosomes.

The main Reason Quaggas can not be cloned is due to the lack of DNA. Scientists have found some DNA but not a full set of 23 pairs of Chromosomes.
Guevodoces have the usual XY male chromosomes. The apparent lack of male genitalia at birth is due to a hormonal deficiency that causes a reduced response to testosterone during fetal sexual development. As a result, the baby boy has small and ambiguous genitalia until sex hormones surge at puberty, causing the external genitalia to develop.
These are known as isochromosomes. They consist of two identical arms due to an abnormal chromosome division where the centromere is duplicated. Despite their similarity in size and centromere position, they lack the genetic diversity found in homologous chromosomes.
Interesting question, I can see why one might wonder this, since a cleft chin may be though of as 'masculine'. I'm a mixed martial artist, and thinking about the anatomy of the cleft chin would tell me the answer is 'no'. The cleft is due to an incomplete formation of fusing the jawbone together, therefore, fighting someone with a cleft chin may even be something to exploit with a nice right hook.
A muscle cramp is likely due to a lack of
No, genetic diversity is not solely due to genes on the sex chromosomes. It is influenced by variation in the entire genome, including genes on autosomes and mitochondrial DNA. Genetic diversity also arises from mutations, gene flow, and genetic recombination during meiosis.
-due to lack of manpower -due to lack of capital -due to geographical dificulties
due to lack of oxygen
due to polyploid nature no of chromosomes are not fixed, though they might be 20-128.
