If the expression of genes in the offspring directly influences their traits, the genes are transmissible from generation to generation, the genes segregate during gamete formation, and the genes of the trait segregate independently, then the genes follow ______ inheritance patterns.
WebMay 14, 2024 · Heterochromatin is of two types: Facultative heterochromatin and constitutive heterochromatin. The genes which get silenced through the process of Histone methylation or siRNA through RNAi are called as facultative heterochromatin. Hence they contain inactive genes and is not a permanent character of every nucleus of the cells.

WebJan 1, 2024 · Protection of euchromatin from invasion by gene-repressive heterochromatin is critical for cellular health and viability. In addition to constitutive loci such as pericentromeres and subtelomeres, heterochromatin can be found interspersed in gene-rich euchromatin, where it regulates gene expression pertinent to cell fate. stp s8481xl oil filterWebHeterochromatin is a functionally distinct genomic compartment that is characterized by its relatively low gene density, enrichment for repetitive sequences and transposable elements, highly compact chromatin architecture, and late onset of DNA replication. stps8h100dWebFacultative heterochromatin. Facultative heterochromatin is a dynamic structure that can convert between the heterochromatin and euchromatin states.
