Welcome to Tutway, a unique platform where learning is fun !
Now there is no distinction between kids' fun time and study time. Say goodbye to the days of cramming those dull and ponderous books, which made learning a tedious task. We believe in the straightforward idea that audio-visual learning is the most effective tool for learning. Many researchers have proven that kids learn a lot by playing interactive games and watching audio-visual animated lessons compared to reading from books. To understand the new concepts, Kids show more interest in adopting unique ways of learning. We have brought a programme that covers the crucial ideas and makes learning more stable that stimulates the critical thinking of the young learners !
Let's break away from our perception that adopting new learning concepts is challenging. You will find our website & youtube channel very user-friendly and interactive to gain knowledge. Even kids can access the content without constant parental supervision !

An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. The most common interaction between alleles is a dominant/recessive relationship. An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.
