Summary
This study shows a girl with cri du chat syndrome has strong morphological skills, correctly inflecting most words and demonstrating knowledge of productive rules despite other language challenges.
Area of Science:
- Linguistics
- Developmental Psychology
- Genetics
Background:
- Cri du chat syndrome is a genetic disorder associated with developmental delays.
- Morphological skills are crucial for language development and communication.
- Understanding language acquisition in rare genetic syndromes provides insights into typical development.
Observation:
- The study focused on a single case of a girl with cri du chat syndrome.
- Data included spontaneous speech and a past tense elicitation test.
- The subject's age ranged from 11 to 16 years during data collection.
Findings:
- The subject demonstrated a high rate of correct word inflection across various word classes.
- Most inflected forms in the corpus were accurate, with few errors.
- The subject showed evidence of applying productive morphological rules, not just rote learning.
Implications:
- Individuals with cri du chat syndrome may possess significant morphological abilities.
- This case challenges assumptions about the universality of language deficits in genetic syndromes.
- Further research is needed to explore the extent of these skills in a larger cohort.

02:25Chirality
Chirality is a term that describes the lack of mirror symmetry in an object. In other words, chiral objects cannot be superposed on their mirror images. For example, our feet are chiral, as the mirror image of the left foot, the right foot, cannot be superposed on the left foot.
Chiral objects exhibit a sense of handedness when they interact with another chiral object. For example, our left foot can only fit in the left shoe and not in the right shoe. Achiral objects — objects that have...

01:17Karyotyping
Overview
01:58X-Inactivation
The human X chromosome contains over ten times the number of genes as in the Y chromosome. Since males have only one X chromosome, and females have two, one might expect females to produce twice as many of the proteins, with undesirable results.
02:30Chirality in Nature
Chirality is the most intriguing yet essential facet of nature, governing life’s biochemical processes and precision. It can be observed from a snail shell pattern in a macroscopic world to an amino acid, the minutest building block of life. Most of the snails around the world have right-coiled shells because of the intrinsic chirality in their genes. All the amino acids present in the human body exist in an enantiomerically pure state, except for glycine - the sole achiral amino acid. The...
01:51Lampbrush Chromosomes
In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops resemble the...

01:43Incomplete Dominance
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.
