What are the two main factors that cause individuals of the same species to appear different?
Genetic variation and environmental factors are the two main factors that cause individuals of the same species to appear different. Genetic variation results from differences in DNA sequences passed down through generations, while environmental factors such as diet, climate, and exposure to sunlight can also influence physical appearance.
What two types of chromosomal mutations?
Two are insertion mutations and deletion mutations.
How is variation produced in each species?
Variation in species is primarily produced through genetic mutations, which are changes in the DNA sequence. These mutations can occur spontaneously or be induced by environmental factors. Additionally, sexual reproduction contributes to variation through the combination of genes from two parent organisms, leading to unique genetic combinations in offspring. Environmental influences and selective pressures also play a crucial role in shaping and maintaining variation within species.
What is the basis variation in traits?
Variation in traits arises from differences in genetic makeup, environmental influences, and the interaction between the two. Genetic variation is primarily due to mutations, gene recombination during reproduction, and the presence of multiple alleles. Environmental factors, such as climate, nutrition, and lifestyle, also play a significant role in shaping traits. Together, these factors contribute to the diversity observed within populations of organisms.
Two humans can have different traits because they?
Two humans can have different traits because of genetic variation, which arises from the combination of alleles inherited from their parents. Environmental factors also play a significant role in shaping traits by influencing how genes are expressed. Additionally, random mutations can introduce new traits, further contributing to individual differences. Together, these factors create the unique combination of characteristics seen in each person.
What are two possible environmental factors that can cause cancer?
Exposure to carcinogens, such as tobacco smoke or ultraviolet radiation, can increase the risk of developing cancer by damaging DNA. Additionally, environmental pollutants like asbestos or radon can also contribute to the development of cancer by causing genetic mutations in cells.
Name two things that can cause cancer?
Cancer is a complex group of diseases, and its causes are often multifactorial. However, two significant factors that can contribute to the development of cancer are: Genetic Factors: Inherited genetic mutations can increase the risk of certain types of cancer. These mutations can be passed down from parents to children and may predispose individuals to a higher likelihood of developing specific cancers. Environmental Factors: Exposure to certain environmental factors can contribute to the development of cancer. This includes exposure to carcinogens, which are substances or agents that can promote the formation of cancer. Carcinogens can be found in pollutants, tobacco smoke, certain chemicals, radiation, and some infectious agents.

What is known to cause autism?
"The cause it not yet known. It seems that no two autistic children are alike. According to the Mayo Clinic, there are many likely causes such as genetic disorders and environmental factors."
What determines the outcome of a mutation?
There are plenty of factors that can induce mutations. There are several harmful rays, such as X-rays and gamma rays, that can affect the DNA structure within gametes and that can cause mutations to occur. There are certain types of food that can also have the same affect. There are also genetic factors that can cause mutations. During Anaphase two where the DNA materials are splitting apart to form gametes, a process known as non-disjunction can occur where one of the gametes has an extra set of chromosome and the other has one or more less set of chromosomes.

What are the two groups of environmental factors that influence organisms?
dioxide and nitrogen
What are the factors that cause evolution to occur?
The two main factors are mutation and natural selection.Mutations are random changes in our DNA that cause changes. Some of these changes are bad, some are neutral, and some are good.This is where natural selection comes in. If the mutation is bad, then that organism is less likely to mate and pass down the gene. The organism dies along with the mutation that made it less fit. If it is neutral, which is what most mutations are, then nothing happens. If it is good, then the organism is more likely to survive and pass down the gene which will then propagate through the species.
