What is an emergenic trait?
An emergenic trait is a complex trait that arises from interactions between multiple genes and environmental factors. These traits are not simply inherited from a single gene but emerge from the interplay of various genetic and environmental influences. Examples of emergenic traits include behaviors, intelligence, and susceptibility to certain diseases.
Is skin color a quantitative trait?
It is indeed. Quantitative traits suggest that the traits are polygenic, which means that the trait is influenced by more than one gene and skin color is influenced by 3 genes (6 alleles). Skin color is also a multifactorial trait because there are also many environmental factors that change skin color, such as exposure to sunlight.
What is the relationship between meiosis and traits?
Meiosis passes down chromosomes to the offspring, which give the offspring its traits. Since the chromosomes are just tightly wrapped up DNA strands, they have genes, and because they have genes, they have alleles, which give the offspring a specific trait. So half of a chromosome would come from the mom, and the other from dad. Hope this helps! Please give me feedback
What is heritability?
When our parents pass away we inherit their possessing. Don't we? The same is said about our genes. We inherit 50% of our genes from mother and 50% from father. Most of our physical features are determined by our genes that we inherited from our parents. The same can be said about our psychological feature. For example, personality is in somewhat is inherited feature from our parents, and in somewhat is socially learned - determined by environmental factors such as education and family influence. Hope this helps
What is a good example of a biological trait?
environmental traits: favorite music, favorite food, favorite stuff both : athletic ability, muscle size
What is it called when three or more contrasting genes control a trait?
When three or more contrasting genes control a trait, it is called polygenic inheritance. This type of inheritance involves multiple genes interacting to influence a single trait, resulting in a continuous distribution of phenotypes in a population.
What do you call chromosome that look alike and carry genes for the same trait?
Chromosomes that look alike and carry genes for the same trait are called homologous chromosomes. The nucleus contains these chromosomes.
Can multiple genes control a single trait?
yes its called pleiotropy
What is a section of DNA that code for a trait?
A section of chromosomes that codes for a trait can be called
When the trait is on the X-chromosomes what is it called?
When a trait is located on the X chromosome, it is referred to as an X-linked trait. This means the trait is inherited through the X chromosome and can show different patterns of inheritance compared to traits on autosomes. Examples of X-linked traits include red-green color blindness and hemophilia.
What are the factors that control a trait called?
The factors that control a trait can include genetic influences (such as genes and alleles), environmental influences (such as diet and exposure to toxins), and the interactions between genetics and the environment. Additionally, epigenetic factors can also play a role in the regulation of gene expression and the manifestation of traits.
Where genes for a certain trait are located?
Genes for a certain trait are located on specific regions of chromosomes. Each gene occupies a particular locus on a chromosome, and variations in these genes can result in different expressions of the trait. The specific location of a gene on a chromosome is referred to as its genetic map position.
What is a trait that is passed from parent to child on the X chromosome called?
Recessive traits on X chromosome are expressed in males because they have only one copy of X chromosome. If they have any recessive gene it will be expressed. In female both the genes should be recessive then only the recessive character will be expressed.
What kind of trait is present when many different genes different genes control a single trait such as skin color?
Polygenic trait.
When many genes control a trait the trait will show a large number of?
Phenotypes
An organismwith two like genes for a triat is called what for that trait?
An organism with two like genes for a trait is called homozygous for that trait.
Is Down syndrome a single gene or polygenic trait?
Down syndrome is a result of having an extra chromosome in one's genes. Chromosome thirteen* if your that much into the science. It is also called trisomy 21 because the chromosome 21 is the one with the abnormalities. *Abnormalities with chromosome thirteen is called Patau syndrome or trisomy 13.
