Every trait in an organism is influenced by which of the following?
By both maternal and paternal DNA equally
The correct answer is option 4 i.e. By both maternal and paternal DNA equally.
- Every trait in an organism is influenced by both maternal and paternal DNA equally.
- This is because each parent contributes half of the genetic material to their offspring through gametes—sperm from the father and egg from the mother.
- These gametes contain 23 chromosomes each, which combine during fertilization to form a complete set of 46 chromosomes.
- Traits such as eye color, height, and blood type are determined by genes inherited from both parents, often showing a mix or dominance of certain inherited characteristics.
सही उत्तर विकल्प 4 है अर्थात मातृ और पैतृक DNA दोनों द्वारा समान रूप से।
- किसी जीव में प्रत्येक गुण मातृ और पैतृक DNA दोनों द्वारा समान रूप से प्रभावित होता है।
- ऐसा इसलिए है क्योंकि प्रत्येक माता-पिता अपने बच्चों को आनुवंशिक सामग्री का आधा हिस्सा युग्मकों के माध्यम से प्रदान करते हैं - पिता से शुक्राणु और माता से अंडाणु।
- इन युग्मकों में प्रत्येक में 23 गुणसूत्र होते हैं, जो निषेचन के दौरान मिलकर 46 गुणसूत्रों का एक पूरा सेट बनाते हैं।
- आंखों का रंग, ऊंचाई और रक्त प्रकार जैसे लक्षण माता-पिता दोनों से विरासत में मिले जीन द्वारा निर्धारित होते हैं, जो अक्सर कुछ विरासत में मिली विशेषताओं का मिश्रण या प्रभुत्व दिखाते हैं।
