How is DNA responsible for the similarities and
differences between parents and offspring

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which two alleles of a gene are present within an organism's chromosomes based solely on the outward appearance of that organism. However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.

Explanation:

In other cases, each parent provides a different allele of a given gene, and the.. In contrast, if a fly has the bb genotype, it will have a black body phenotype. In other words, even though alleles of two different genes were involved in this .
