The inheritance pattern for genes compacted in the DNA of mitochondrion and chloroplast. Introduction: All eukaryotic organisms contain chromosomes, and the number of chromosomes varies in different organisms. In humans and several other species, diploid (2n) number of chromosomes is present. The diploid number of chromosomes indicates that each parent contributes equally to the offspring. Therefore for humans, the diploid and haploid number is 46 and 23, respectively. Of these, 22 pairs are perfectly similar in both females and males and are referred to as autosomes. The rest of the pair is referred to as sex chromosomes: XY in males and XX in females. Doubling of gene products (sex-linked) is ultimately prevented by dosage compensation

Question

Features of a Concept Features of a Concept Characteristics are discrete; that is, they are unitary. Genetic features have alternative forms, and each feature is inherited from one of the two parents. These are called alleles. One allele is dominant over the other allele. The dominant allele is reflected in the phenotype. Random segregation creates the gametes. The heterozygotic individuals produce gametes with an equal frequency of both alleles. Genes are unlinked; that is, different traits arise from the independent assortment.
