What are the odds of trisomy 21? If black fur in cows is dominant and white fur is recessive, what is probability of getting an offspring with black fur with two white fur parents? How can a random distribution of alleles result in a predictable ratio?
Sex differences in psychiatric disorders are the result of a complex interplay between genetic, hormonal, immunological, and psychosocial factors [2,3,16,17,18,19,20,21,22,23]. Adding to this complexity, the diagnosis of psychiatric disorders is currently based on behaviorally defined DSM criteria...
In a cross between pea plants that are heterozygous for purple flower color (Pp), what is the probability that the offspring will be homozygous recessive? Can we use Punnet square? Is trisomy 18 autosomal dominant or recessive? Is trisomy 13 autosomal dominant or recessive?
Nondisjunction:Failure of paired chromosomes to separate (to disjoin) during cell division, so that both chromosomes go to one daughter cell and none go to the other. Nondisjunction causes errors in chromosome number, such as trisomy 21 (Down syndrome) and monosomy X (Turner syndrome). What a...
The study of sexual dimorphism in psychiatric and neurodevelopmental disorders is challenging due to the complex interplay of diverse biological, psychological, and social factors. Males are more susceptible to neurodevelopmental disorders including inte

Women with triple X syndrome can be a little more likely to experience health problems than women without the condition, but these issues vary greatly from person to person. There’s some evidence that autoimmune disorders, such as lupus and rheumatoid arthritis, are associated with trisomy X, ...
This is the most common type of PGT. Most human cells have 23 pairs of chromosomes, for a total of 46 chromosomes. However, in aneuploidy, there are extra or missing chromosomes. One extra chromosome is termed trisomy. A missing chromosome is referred to as monosomy. Most cases of ...

What genetic mutation causes trisomy 18? What is an example of an autosomal recessive trait? What kind of mutation causes trisomy 21? What does FOXP2 genetic mutation cause and why? What are the hallmarks of autosomal recessive traits?
