The size of the genome does not necessarily increase with an increase in the complexity of organisms. This is referred to as ‘C paradox’. E.g. a... View Article
During the follicular phase of the menstrual cycle, the primary follicle in the ovary grows to become a mature Graafian follicle. Maturation of... View Article
Sex of a person is determined by the pair of sex chromosomes. Females have a pair of X chromosome (XX) and males have X and Y chromosome, i.e.... View Article
Adaptive radiation refers to the rapid evolution of various different species from a common parent species. It leads to speciation. Adaptive... View Article
Yes, the most common type of colour blindness is a sex linked hereditary disorder. It is a X-linked recessive disorder. The disease mostly... View Article
Colour blindness is X-linked recessive disorder. Females can be colour blind but for that they have to inherit both the affected genes. The... View Article
Bottlenecks are caused when a catastrophic event drastically reduces the population size. It reduces the genetic diversity in a population and... View Article
Jacob’s Syndrome is a genetic condition with an extra Y chromosome. It is a rare disease, which affects 1 in 1000 male children. Men with Jacob’s... View Article
The genetic code is degenerate, i.e. one amino acid is coded by more than one codon. Francis Crick proposed the wobble hypothesis to explain the... View Article
Genetic variation is the main driving force of natural selection and evolution. Genetic variations help the population survive in the changing... View Article
Yes, genetic code is continuous and non-overlapping. Genetic code is the trinucleotide sequence present on the mRNA transcript, which codes for a... View Article
Heterozygosity refers to the frequency of heterozygous genotypes in a population. High heterozygosity is an indication of more genetic variation.... View Article
Genetic variations existing in a population is studied under population genetics. ‘K’ is an important parameter, which refers to the number of... View Article
Hardy Weinberg equation can be used to calculate allele frequencies and genotype frequencies in a population and analyse any changes occurring... View Article
The Hardy Weinberg equation is used to calculate the genetic variation in a population, which is in equilibrium. We can calculate the allele... View Article
