- Uniparental disomy and imprinting modify gene expression with passage through maternal or paternal meiosis.
- We found that the rate of chromosome I disomy among vik1 spores was indistinguishable from that observed in wild-type strains.
- It may be of interest to examine the sperm of men with different sized Y chromosomes to see whether there is a relationship between the level of sex chromosome disomy and Y chromosome size.
- Some cases of AS result from inheritance of both chromosomes in the 15 pair from the father, an unusual genetic phenomenon known as uniparental disomy.
Derivatives adjectivedʌɪˈsəʊmɪk Genetics Over time, however, diploidization of the genome occurs and disomic segregation becomes prevalent. Example sentencesExamples - Given that cultivated peanut is a disomic polyploid, 20 linkage groups were expected.
- We again found some events to be disomic for chromosome III.
- Many polyploids, however, have disomic chromosome behavior.
- Segregation patterns in families suggested a partially duplicated genome structure and disomic inheritance.
