8 What makes the elationship between genes and traits complicatec in humans? T Type Draw square

The relationship between genes and traits in humans is complicated due to several factors:1. **Polygenic Inheritance**: Many traits are influenced by multiple genes rather than a single gene. This polygenic inheritance can result in a wide range of phenotypes.2. **Epigenetics**: Environmental factors can influence gene expression without altering the DNA sequence. Epigenetic modifications can turn genes on or off, affecting traits.3. **Gene-Environment Interaction**: The environment can interact with genes to influence the expression of traits. For example, a person might have a genetic predisposition to a certain disease, but whether they develop the disease can depend on environmental factors.4. **Non-coding RNAs**: These molecules regulate gene expression by binding to DNA or influencing the activity of other genes. They play a significant role in development and disease.5. **Genetic Recombination**: During meiosis, chromosomes are shuffled and recombined, leading to new combinations of genes in offspring. This increases genetic diversity and can result in novel traits.6. **Incomplete Dominance**: In some cases, neither allele is completely dominant over the other, resulting in a blended phenotype.7. **Genetic Imprinting**: Certain genes are expressed in a parent-of-origin-specific manner, meaning they are only active when inherited from a specific parent.8. **Mutations**: Changes in the DNA sequence can lead to new traits or alter existing ones. Mutations can be beneficial, neutral, or harmful.These factors contribute to the complexity of understanding how genes determine traits in humans.
