Genes change over time through mutations, which are alterations in the DNA sequence. Factors that contribute to these changes include environmental factors, such as exposure to radiation or chemicals, as well as errors that occur during DNA replication. Additionally, genetic recombination during sexual reproduction can also lead to genetic variation and changes in genes over time.

What did Mendel call the factors thy determine traits?
Mendel called the factors that determine traits "genes." He observed that these genes are passed down from parents to offspring and contribute to the inherited characteristics of an organism.
How can environmental factors impact gene expression?
Environmental factors can impact gene expression by influencing the activation or suppression of specific genes. Factors such as diet, stress, toxins, and exposure to pollutants can modify the way genes are expressed, leading to changes in an individual's traits and health outcomes.
What factors determine why some genes are responsible for an increased risk of cancer?
Genes that are responsible for an increased risk of cancer are determined by a combination of genetic factors, environmental factors, lifestyle choices, and family history. Mutations in certain genes, such as tumor suppressor genes or oncogenes, can increase the likelihood of developing cancer. Additionally, exposure to carcinogens, unhealthy habits like smoking or poor diet, and a family history of cancer can also contribute to an elevated risk.
What besides genes influence traits?
The environment.
How can mutations in different genes contribute to the development of a single disease?
Mutations in different genes can contribute to the development of a single disease by affecting various biological pathways or processes that are involved in the disease. These mutations can interact with each other or with environmental factors to disrupt normal cellular functions, leading to the manifestation of the disease.
Do some genes change as you get older and others stay the same?
Genes do not change, your DNA stays the same during your entire life. But when your grow older, the transcription from DNA to a certain characterestic might not be optimal any longer, which makes us look aged.
Can genes change?
Genes themselves do not change, but mutations can occur in genes, leading to changes in the genetic code. These mutations can be caused by various factors such as errors during DNA replication or exposure to mutagens. Over time, these changes may result in genetic variation within a population.
What are the three factors that contribute to the makeup of an individual?
Genes, Chromosome, Cell Division
What did Mendel call the factors thy determine traits?
Mendel called the factors that determine traits "genes." He observed that these genes are passed down from parents to offspring and contribute to the inherited characteristics of an organism.
What is a change in genetic makeup of a cell?
A change in the genetic makeup of a cell refers to alterations in the DNA sequence of an individual gene or set of genes. This can result from mutations, gene rearrangements, or epigenetic modifications, leading to changes in the expression or function of proteins encoded by those genes. These changes can impact various cellular processes and potentially contribute to disease development.
What genetic factors might be responsible for a change in an organism's body plan?
Changes in body plan can be influenced by mutations in key developmental genes, such as Hox genes, which regulate the spatial organization of body structures. Alterations in regulatory genes, like transcription factors, can also impact body plan formation. Additionally, changes in gene expression patterns during development can lead to modifications in the body plan of an organism.
Can a persons genes change as they age?
No, a person's genes do not change as they age. However, the way genes are expressed can be influenced by various factors, such as lifestyle, environment, and health conditions, which can impact how genes function over time.
What is a change in a population over time that also changes the genes in the gene pool?
Evolution.
What three ways are human traits controlled?
Human traits are controlled by a combination of genetic factors (inherited from parents), environmental factors (such as diet and lifestyle), and epigenetic factors (changes in gene expression without changes in the underlying DNA sequence). These factors interact in complex ways to influence the development and expression of human traits.
When a gene changes within a life span?
When genes change within a life time it is adaption.
Change in population over time which also changes the genes in the gene pool?
Simply, evolution.
Change in a population over time which also changes the genes in the gene pool?
Simply, evolution.
