- How do Mendel's experiments show that traits are inherited independently? Mendel crossed pure breeding tall plants having round seeds with pure breeding short plants having wrinkled seeds. The plants of F_(1 )gener... 1
- How do Mendel's experiments show that traits may be dominant or recessive? The trait which appears in all the members of F_(1 )generation and also in 75% numbers of F₂ generation obtained by self fertilization of F₁... 1
- How does the creation of variations in a species promote survival? Variations occur due to sexual reproduction and also due to inaccurate copying of DNA. Depending on the nature of variations, different indi... 1
- If a trait A exists in 10% of a population of an asexually reproducing species and a trait B exists in 60% of the same Trait B because in asexual reproduction traits which are present in the previous generation are carried over to next generation with minimal... 1
