Can environmental factors affect the coding of genes?
Yes, environmental factors can significantly influence gene expression through a process known as epigenetics. Factors such as diet, stress, toxins, and temperature can lead to chemical modifications of DNA or histones, affecting how genes are turned on or off without altering the underlying DNA sequence. This means that environmental conditions can ultimately impact an organism's traits and behaviors by modifying how genes are expressed.
What is the condition called when there are many genes that affect a trait which are susceptible to changes due to environmental factors?
Multifactorial trait
What is the condition called when there are many genes that affect a trait which are susceptible to changes due to the environmental factors?
This condition is known as polygenic inheritance. It involves multiple genes contributing to a trait, and the expression of these genes can be influenced by environmental factors. The combination of genetic and environmental influences leads to a wide range of variation in the trait.
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.
How many protein coding genes are present in the human genome?
There are approximately 20,000 to 25,000 protein-coding genes in the human genome.
Genes that are transcribed are called?
Genes that get transcribed is called structural gene. It is also known as the amino acid coding region.Our genome is made up of alternating introns and exons.Introns are the non-coding region the the genome whereas exons are the coding sequences.
How many protein-coding genes are approximately present in the human genome?
There are approximately 20,000 to 25,000 protein-coding genes in the human genome.
Is a persons height determined by genes only?
No. Height can also be determined by environmental factors such as diet.
What best describes the factors that affect a phenotype?
The genotype and the environment both affect a phenotype.
What is the difference between inherited and enviromental factors?
An inherited factor is passed on through the genes of the parents. An environmental factor has to do with influences in the environment. Inherited factors cannot be changed, while environmental factors usually can be.
Is obesity caused by genetic factors or environmental factors?
Both if you are an inactive person your body will reflect it, when you have kids they usually have that now in their genes.
What percentage of the human genome is comprised of protein-coding genes?
Approximately 1-2 of the human genome is made up of protein-coding genes.
