Genetics is the study of genes.
<span>Fruit flies and pea plants may seem boring and simple, but the basic principles of genetics were worked out using those organisms. Humans follow the same patterns of heredity. First, meiosis independently assorts chromosomes when gametes are made for sexual reproduction. Second, human heredity involves the same relationships between alleles—dominant and recessive interactions, polygenic traits, and sex-linked genes, among others.</span>
Organisms show dominant traits in most cases, hope this helps :)
Frank would have naturally curly hair because of his hereditary genes. That means that his parents would have A curly hair Gene therefore he has the curly hair Gene as well .
