Ever wondered which language of the two — maternal or paternal — has a stronger influence on your child? According to a study, while vocabulary is influenced by the father, the understanding of sounds is derived from the mother.

Mother tongue hypothesis refers to the language usage that follows matrilineal inheritance.

Father tongue hypothesis, on the other hand, refers to the paternal lines that dominate the local language in an already populated region, which was proposed based on genetic and anthropological researches.

The researchers found that in Indo-European populations, the paternal lineages (Y-chromosome) were correlated to the vocabulary (lexicon) of their languages while the maternal lineages were associated with their pronunciations (phoneme).

The unbalanced correlation between genetics and linguistics can be explained by male-dominant population contact, and the strategy of language learning by local females which is similar to the second language acquisition, said lead author Menghan Zhang from the Carnegie Mellon University in Pennsylvania, US.

For the study, published in the journal National Science Review, the team explored the genetic-linguistic relationship of 34 populations speaking different Indo-European (IE) languages.

They assembled compositions of the Y-chromosomal and mitochondrial DNA haplogroups or paragroups from these IE populations, which reflect paternal and maternal lines, respectively.

These haplogroups or paragroups were defined using stable mutations so that they were all already formed in the Paleolithic Age (over 10,000 years ago).

Children and youths whose mothers had diabetes during their pregnancy are themselves at an increased risk of the disorder, say researchers, including one of Indian-origin.

The study showed that a child or teenager whose mother had gestational diabetes — diabetes during pregnancy — was nearly twice as likely to develop diabetes before the age of 22 years.

The association was found in children from birth to the age of 22 years, from birth to 12 years, and from 12 to 22 years, said the study, published in Canadian Medical Association Journal.

“Although Type-1 and Type-2 diabetes in parents are well-established risk factors for diabetes, we show that gestational diabetes mellitus may be a risk indicator for diabetes in the mother’s children before age 22,” said Kaberi Dasgupta, clinician-scientist from the McGill University in Canada.

“This link of diabetes in children and youth with gestational diabetes in the mother has the potential to stimulate clinicians, parents, and children and youth themselves to consider the possibility of diabetes if offspring of a mother with gestational diabetes mellitus develop signs and symptoms such as frequent urination, abnormal thirst, weight loss or fatigue,” said Dasgupta.
