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 is it called when you are heterozygous for two traits?
When an individual is heterozygous for two traits, it is referred to as being dihybrid. In this case, the individual has two different alleles for each of the two traits being considered. For example, if considering traits A and B, a dihybrid organism might have the genotype AaBb, where A and a are different alleles for one trait and B and b are different alleles for another trait.
What does a genes have two or more of?
Genes can have two or more alleles, which are different versions of a gene that can exist at a specific locus on a chromosome. These alleles can contribute to variations in traits among individuals. In diploid organisms, such as humans, genes typically have two alleles, one inherited from each parent. The combination of these alleles can determine the expression of specific traits.
What traits such as stem length in plants and skin color and height in humans are controlled by two or more genes. What is this called?
Traits controlled by two or more genes are referred to as polygenic traits. In plants, stem length can be influenced by multiple genes, while in humans, traits like skin color and height result from the interaction of several genes. This complexity leads to a range of phenotypes, as the combined effects of these genes create continuous variations rather than discrete categories.
What are the four potential gametes of an individual that is heterozygous for two traits?
The four potential gametes of an individual that is heterozygous for two traits are formed due to independent assortment. Each gamete can inherit different combinations of alleles for those two traits, leading to genetic diversity in the offspring.
What is it called when two different creature are merged together?
When two different creatures are merged together, it is called a hybrid. Hybrids can exhibit traits from both original creatures.
What are two sex-linked traits present in humans?
Two sex-linked traits present in humans are color blindness and hemophilia. These traits are carried on the X chromosome and are more commonly expressed in males due to their inheritance pattern.
How can birds fly when humans can't?
Because humans and birds are two completely different organisms and they have evolved along different evolutionary pathways.
Why would two animals have different traits?
different traits between different animals are developed because of evolution. when an animal lives in a certain environment, after a few generations it will start to evolve to fit its new living space. animals in different living spaces will evolve differently. if two animals share the same living space and are different, it is because they have different DNA and because they had different starting points in their evolutions.
Two genes for two different traits are said to be what?
linked
What were George Washington traits?
None. Two different men in two different times.
What were George Washington Bush's traits?
None. Two different men in two different times.
What is it called when you are heterozygous for two traits?

For example, if considering traits A and B, a dihybrid organism might have the genotype AaBb, where A and a are different alleles for one trait and B and b are different alleles for another trait.
How does a cross between two different traits in genetics result in the expression of a new phenotype?
When two different traits are crossed in genetics, the offspring can inherit a combination of the traits from each parent. This combination can lead to the expression of a new phenotype, which is the observable characteristics of an organism. This is because different genes interact and influence each other to produce a unique trait that may not be present in either parent.
What organisms is heterzygous?
A heterozygous organism has two different alleles for a given gene. The opposite of a heterozygous organism is a homozygous organism which has two alleles that are the same for that specific gene. Genes can exist in more than one form and the different forms are called alleles. Alleles code for different types of the same characteristic
What traits did modern humans inherit from australopithecus afarensis?
Modern humans have inherited certain traits from Australopithecus afarensis, such as bipedalism (walking on two legs), similar dental patterns, and the potential for longer childhood development periods. These traits are believed to have played a role in the evolution of hominins leading up to modern humans.
What does a genes have two or more of?

If traits that are passed on by parents are different they are said to be?
If traits passed on by parents are different, they are said to be heterozygous. This means the individual has two different alleles for a particular gene.
