What traits are altered by the environment?

Explanation: Environmental factors influence traits in plants and animals. These traits include things like weight, height, size, and color. If a child does not get proper nutrition, their height may be stunted as an adult.

What are the two ways variations in traits are created?

Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.

What are two environmental factors that are likely to affect gene expression?

In addition to drugs and chemicals, temperature and light are external environmental factors that may influence gene expression in certain organisms.

What are examples of environmental traits?

Examples of environmental traits are your favorite music, being a good basketball player, and the language you speak. These traits are environmental traits because they are traits that you choose or learn, or that are influenced by the place you live. Explore the inherited traits and learned behaviors of a classmate.

What two factors can affect an organism traits?

The environment in which an organism lives can affect many of its inherited traits. Food, temperature, sunlight, and water are examples of environmental factors that can affect an organism's traits. Many characteristics of plants and animals involve both inheritance and the environment.

What are two variations or different versions of this trait?

Different versions of a gene are called alleles. Alleles are described as either dominant or recessive depending on their associated traits.

How environmental factors affect the variation and distribution of expressed traits in a population?

Environmental factors can also cause mutations in genes, and viable mutations are inherited. expression of traits, and hence affect the probability of occurrences of traits in a population. Thus the variation and distribution of traits observed depends on both genetic and environmental factors.

What are the two types of variation?

There are two forms of variation: continuous and discontinuous variation. Characteristics showing continuous variation vary in a general way, with a broad range, and many intermediate values between the extremes.

How does environmental factors affect the expression of traits?

Environmental factors such as diet, temperature, oxygen levels, humidity, light cycles, and the presence of mutagens can all impact which of an animal's genes are expressed, which ultimately affects the animal's phenotype.

How does the environment affect genetic variation?

These results suggest that ecological factors can have strong impacts on both population size per se and intrapopulation genetic variation even at a small scale. On a more general level, our data indicate that a patchy environment and low dispersal rate can result in fine-scale patterns of genetic diversity.

Can environment change genes?

Environmentally induced changes in gene expression occur when exposure to chemicals changes which genes are turned “on” or “off”—which can change how the cells function and thus a person's predisposition to disease. The effect of this chemical modification is called epigenetic regulation.

What are 5 environmental characteristics?

Conditions are observed on the basis of five environmental characteristics: safety, amenity, accessibility, sociability, and attractiveness.

What trait is influenced by both environment and genetics?

Like most aspects of human behavior and cognition, intelligence is a complex trait that is influenced by both genetic and environmental factors. Intelligence is challenging to study, in part because it can be defined and measured in different ways.

What are some factors that may brought changes in the traits and behavior of an organism?

Food, temperature, sunlight, and water are examples of environmental factors that can affect an organism's traits. Many characteristics of plants and animals involve both inheritance and the environment. Learned experiences can change animal behavior and affect animal traits as they develop.

What are some environmental factors that can cause epigenetic changes?

Epigenetic marks can be affected by exposure to metals, air pollution, benzene, organic pollutants, and electromagnetic radiation [98]. Chemical and xenobiotic compounds in water or the atmosphere are other potential environmental stressors capable of changing epigenetic status.

What are some environmental factors that can affect the growth of organisms?

So what environmental conditions can affect microbial growth? Temperature, oxygen, pH, water activity, pressure, radiation, lack of nutrients…these are the primary ones.

What environmental factors may increase the incidence of chromosomal aberrations?

Other factors that can increase the risk of chromosome abnormalities include maternal age (the frequency of meiotic nondisjunction increases with maternal age) and environmental factors such as exposure to certain drugs.
