NOTES > Mendel’s Genetics

 

DNA and RNA are carriers of genetic information. Ribosomes are found in all forms of life. Major features of the genetic code are shared by all modern living systems. Core metabolic pathways are conserved across all currently recognized domains. Mendel’s laws of segregation and independent assortment can be applied to genes that are on different chromosomes. Fertilization involves the fusion of two haploid gametes, restoring the diploid number of chromosomes and increasing genetic variation in populations by creating new combinations of alleles in the zygote— a. Rules of probability can be applied to analyze passage of single-gene traits from parent to offspring. b. The pattern of inheritance monohybrid, dihybrid, sex-linked, and genetically linked genes) can often be predicted from data, including pedigree, that give the parent genotype/phenotype and the offspring genotypes/phenotypes.
