Is it true that 50% of human DNA is the same as bananas?

We have a common sense that people can donate blood to each other, because research shows that the genetic similarity between people is great, so people will wonder, is 50% of human DNA as real as bananas? The answer is of course not, because bananas and people are different species. Although people can donate blood to each other, not everyone can, not to mention bananas and people are so different.

Bananas are plants, while people are animals. Although many species in nature use a set of codons, various combinations of codons form genes, and it has been found that the similarity between banana DNA and human DNA is only about 40%, less than 50%. Although there are only dozens of codons in nature, they are just like permutation and combination in mathematics. But there are many answers. Similarly, codons will be arranged and combined into many genes in different ways, which is why the similarity between bananas and humans in DNA is less than 50%.

Take the most common example in our life. Apart from the influence of environment, a child's genes are mainly determined by the presence of parents, which is also the key to what codons are provided by both parents. A large number of experimental research results of scientists show that the DNA in a child, in general, has almost perfect similarity with his father and extremely high similarity with his mother.

But that's because children and parents are immediate family members, while bananas and people are not immediate family members, but two completely different species. But because we all use a set of codons, banana and human DNA are similar to some extent, but only about 40%. Due to the different combinations of codons, the similarity between them is less than 50%.
