The cytoplasm of eukaryotic cells contains organelles such as mitochondria, chloroplasts, Golgi bodies, lysosomes, peroxisomes etc. Out of these mitochondria and chloroplasts contain DNA.
Genes are found on the chromosomes and chromosomes are made up of DNA and associated proteins. Thus, mitochondria and chloroplasts also contain genes.
During fertilization male gametes do not have sufficient amount of cytoplasm, hence, organelles, so most of the cytoplasm to the offsprings is contributed by egg itself. Hence, organelles that are present in eggs cytoplasm, also inhibit to the offprings.
