Question

Which of the following choices accurately describe what makes one person different from another with regard to traits (such as height) that have a very high heritability?

Choose all that apply

Group of answer choices

Random factors during development is the most significant causes of differences between people

None of the other choices are accurate

What makes us different is not that we have different genes, but that we have different alleles of many of those genes

What makes us different from each other is that we have different genes from each other

Most of us have exactly the same genes and alleles, and it’s the environment we were raised in that makes us different

Answer 1

The correct option is : What makes us different is not that we have different genes, but that we have different alleles of many of those genes

Explanation:

Alleles are different forms of genes. Each person has 2 alleles, one obtained from father and the other obtained from mother. But the combination of those alleles obtained from the parents need not be same for all individuals which causes differentiates. Moreover, during gamete formation the combination of homologues chromosome (paternal and maternal) is not same for all gametes. That is during gamete formation it is not necessary one gamete contains paternal chromosome alone and the other maternal alone. The combination of paternal and maternal chromosome during gamete formation varies.
