Extra nuclear inheritance is also known as cytoplasmic inheritance. Extra nuclear inheritance is transmission of genes, which occurs outside the nucleus. The small circular chromosomes known as extra nuclear occurs in two types of organelles in cytoplasm of cell. In animals these organelles are mitochondria and in plants cells mitochondria and chloroplast. Phenotypic is defined as observable characteristics of an organism, resulted from expression of genes. Phenotypic sex is determined by internal and external genetilia as well as secondary sexual characteristics and behaviour. A chromosome abnormality is disorder characterized by morphological alteration in single or multiple chromosome that affects autosomes, allosome or both. Extra nuclear inheritance The answer is mitochondria, extra nuclear inheritance commonly occurs in cytoplasm organelle such as mitochondria. Extra nuclear or cytoplasmic DNA located in two types of cell organelles, that contains small circular chromosome present in cytoplasm of cells. Ribosomes are complex of RNA and protein that consists of smaller and larger sub units. It is located in cytoplasm and associated with synthesis of protein. Autosomes is any of chromosome but not sex chromosome and associated with various metabolic functions of the cell except determination of sex Sex chromosome involves in sex determination. Males have one X and one Y chromosome, while females have two X chromosomes. Phenotype is an observable type of an organism. It refers to morphology or physical form and structure, behaviour and developmental process. The answer is XX individuals. XX individual is rare intersex condition, in which individual contains 46 XX karyotype and associated with phenotypically male characteristics. The klinefelter syndrome is associated with extra copy of X chromosome in each cell (XXY). XO sex determination is determination of species such as insects, arachnids and mammals. Male have only one sex chromosome XO and females haves two XX. XXX individuals or triple X syndrome is genetic disorder, that affects females. The answer is aneuploidy Polyploidy is whole genome duplication, that contains more than two set of chromosomes. A normal diploid cell of organism contains more than two basic set of chromosomes. Polyploidy may occur due to abnormal cell division. Aneuploidy is the condition, in which there are abnormal number of chromosomes in cell Examples of chromosomal aneuploidy include down syndrome and trisomy. It is more common in humans. Heterogamy is sexual reproduction, that involves fusion of unlike gametes that differ in physiology, size and structure. Triploid syndrome or triploidy is genetic disorder, in which off spring has extra set of chromosomes, that is either from father or mother.
