The yoni vyapad namely “shandi” is an example for the abnormalities in gametes (beeja dushti) leading to the deformity of anatomical structures (ashaya) in fetus due to affliction of [[vata]]leading to the female progeny with underdeveloped primary and secondary sexual characters [Cha. Sa. [[Chikitsa Sthana]]30/34-35] which is generally correlated by many scholars with the chromosomal disorder known as “turner syndrome”.

Similarly the defect in the sperm (shukra) in various levels causes deformities related to paternal origin. [Cha. Sa. [[Sharira Sthana]] 4/30-31]

A history of either several spontaneous abortions or offspring with multiple anomalies is an indication for chromosome analyses on both parents. Among known gene disorders, the severity of X-linked disorders differs in males and females. Gene mutations originate more frequently among males, and the frequency increases with advancing paternal age, particularly implicated are the Marfan syndrome, achondroplasia, hemophilia A, and the Lesch-Nyhan syndrome.

Some genetic conditions are caused by mutations in only a single gene. These conditions are usually inherited in different patterns, depending on the type of gene.
 
Some genetic conditions are caused by mutations in only a single gene. These conditions are usually inherited in different patterns, depending on the type of gene.
Pattern of inheritance Description Example
  −
X-linked dominant • By mutations in genes on the X chromosome.
  −
• In females, a mutation in one of the two copies of the gene in each cell is sufficient to cause the disorder.
  −
• In males, a mutation in the only copy of the gene in each cell causes the disorder.
  −
• In most cases, males experience more severe symptoms of the disorder than females. fragile X syndrome
     −
X-linked recessive • Caused by mutations in genes on the X chromosome.
+
{| class="wikitable"
• In females, a mutation would have to occur in both copies of the gene to cause the disorder.
+
|-
• In males, one altered copy of the gene in each cell is sufficient to cause the condition.

Many health conditions are caused by the combined effects of multiple genes which are known as polygenic. It may be by the interactions between genes and the environment also.

Excellence of uterus/female reproductive tract (kshetra) is an essential factor for the normal growth and development of fetus. The accessory structures like placenta (apara) and umbilical cord(nabhi nadi) also play a great role in nourishment of fetus(garbha poshana). Any defect in these structural entities certainly affects the fetus and may lead to some congenital deformities.
