DNA, Genes, Cells, and Mendelian Geneticskaryotes is made up of DNA that is not contained in any cellular compartment, whereas in eukaryotes, the cell nucleus contains several molecules of DNA organized into chromosomes. Chromosomes are the collection of DNA and some of its associated proteins. Normally, in eukaryotes there are several typAER 发表于 2025-3-30 12:24:42
Gene Interactionsaits are studied at the same time). There are several reasons for this behavior, with the changes in phenotypic frequencies as a consequence of changes in genotypic frequencies being the first thing to study. When the genotypic frequencies change, the probable causes are sex-linked inheritance, geneAmendment 发表于 2025-3-30 16:55:57

Gene Linkageuent than between distant genes, with the result that the alleles of these closely spaced genes are transmitted together to the offspring and therefore their segregation becomes rare..The closeness of these genes is called linkage. The closer the genes on a chromosome, the more closely linked they a责怪 发表于 2025-3-31 02:21:18
Extranuclear Inheritancey the DNA in this cell compartment, there are appreciable amounts of DNA in cytoplasmic organelles such as mitochondria (in animals and plants) and chloroplasts (in plants). The DNA present in these organelles is also transcribed and translated, and therefore has the possibility of producing polypep鞭子 发表于 2025-3-31 06:54:57
Chromosomal Mutationsantage that these variants confer on the individuals who carry them. These changes or variants are called mutations, which can be gene mutations (also known as point mutations) or chromosomal mutations. Gene mutations alter one or a few nucleotides within the gene, while chromosomal ones affect enti
