Genotype Expression
Genotype expression is a pivotal concept in genetics, elucidating how an organism's genetic information manifests in its observable traits. It encompasses the intricate processes through which genes, inherited from parents, interact with environmental factors to dictate an individual's phenotype. This interplay between genetic code and external influences governs the development, functioning, and overall characteristics of living organisms. Understanding genotype expression is fundamental not only for unraveling the intricacies of inheritance but also for advancing fields such as personalized medicine, evolutionary biology, and genetic engineering.
Questions
- One pair of alleles controls eye color in fruit flies. More than ten different eye colors are possible, ranging from bright red to apricot to tan to white. What kind of inheritance is this? How do you know?
- A pea plant that has round seeds has the genotype Rr. It is crossed with a pea plant that has wrinkled seeds and the genotype rr. What is the probability that the offspring will have wrinkled seeds?
