What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
Traits controlled by two or more genes are called what?
Traits controlled by two or more genes are called polygenic traits. In polygenic inheritance, multiple genes work together to produce a particular phenotype, resulting in a wide range of possible variations. Examples include height, skin color, and eye color in humans.
List the types of traits that exist?
There are physical traits, such as hair or eye color, and behavioral traits, like shyness or aggressiveness. Additionally, there are inherited traits, which are passed down from parents, and acquired traits, which are learned or developed through experiences.
How similar is the DNA of dogs and humans?
The DNA of dogs and humans is about 84 similar. This means that there are many genetic similarities between the two species, but also significant differences that account for their unique characteristics and traits.
What are the sex-linked traits in humans and how do they differ between males and females?
Sex-linked traits in humans are genetic characteristics that are carried on the sex chromosomes, X and Y. In males, who have one X and one Y chromosome, sex-linked traits are typically passed down from the mother on the X chromosome. In females, who have two X chromosomes, sex-linked traits can be passed down from both parents. This means that males are more likely to exhibit sex-linked traits if they inherit a recessive gene on their X chromosome, while females need to inherit two recessive genes, one from each parent, to show the trait.
What traits seems to disappear when two different genes for same trait are present?
Recessive
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.
When traits seem to disappear when two different genes for the same trait are present?
NO, the traits do not disappear they are simply "masked". According to Mendelian theory there are DOMINANT (A) and RECESSIVE (a) traits. When Aa is present the recessive trait is masked therefore it does not show up. These are called alleles.

What two traits have helped humans quickly become a powerful?
Complex brains and strong opposable thumbs
Which traits oberved were dominant and recessive?
In genetics, dominant traits are those that are expressed when an individual has one or two copies of the dominant allele, while recessive traits are only expressed when an individual has two copies of the recessive allele and no dominant allele present. Dominant traits often mask recessive traits in heterozygous individuals.
Comapre and contrast dominant and recessive traits?
Dominant traits are characterized by a single copy of a gene being sufficient to express a certain trait, whereas recessive traits require two copies of the gene (one from each parent) for the trait to be observed. Dominant traits typically mask the expression of recessive traits when both are present.
How is Dominant and Recessive differ?
Dominant traits are expressed when just one copy of the gene is present, while recessive traits require two copies to be expressed. Dominant traits mask recessive traits when they are both present.
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.
How did gregor mendel describe dominant and recessive traits?
Gregor Mendel described dominant traits as those that are expressed when present, masking the effect of recessive traits. Recessive traits are only expressed when two copies of the allele are present. Mendel's work laid the foundation for understanding inheritance patterns and the concept of genetic dominance.
What genes are recessive traits?
These traits are called dominant traits. They will overcome the recessive gene and the dominant trait will be expressed. A recessive gene needs two alleles present in its genotype to be expressed.
