What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
What is the two alleles letters for one traits that are different?
The two alleles for a trait that are different are represented by two different letters, typically one uppercase and one lowercase. For example, if the trait is flower color, the alleles could be represented as "R" for a dominant red color and "r" for a recessive white color. This combination of different alleles is referred to as heterozygous.
What type of traits is inherited if an organism receives recessive alleles?
The trait received is recessive.
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
Can several alleles affect a single trait?
Yes, multiple alleles (variants of a gene) can contribute to traits through various mechanisms such as incomplete dominance, co-dominance, or polygenic inheritance. For example, eye color is influenced by multiple alleles of different genes that collectively determine the final phenotype.
What is the significance of an individual being heterozygous for a particular trait?
Being heterozygous for a trait means having different alleles for that trait. This can result in a combination of traits from both alleles, leading to increased genetic diversity and potentially advantageous traits.
An organisim whose alleles for traits are identical?
An organism whose alleles for traits are identical is said to be homozygous for that particular trait. This means it carries two identical alleles for that specific gene. For example, if an organism has two alleles for blue eyes and both are the same, then it is homozygous for blue eyes.
What are different versions of a gene for the same trait called?
Different versions of a gene for the same trait are called alleles. Alleles can result in different observable traits depending on their specific sequence and how they interact with each other.
How are dominant and recessive genes?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.
How are recessive and genes related?
If you are talking about traits, dominant traits and recessive traits both have alleles. Dominant traits are alleles that cover up the expression of other alleles. One dominant allele with one recessive allele makes a dominant trait. Two dominant alleles together also make a dominant trate. Recessive traits are alleles that are only expressed when there is no dominant trait to cover them up. Two recessive alleles make a recessive trait. Traits can be passed over to the next generation. Two alleles together make a genotype, which is the inherited combination of alleles. Alleles: different versions of the same gene. Heredity: determined by genes. Genes: piece of DNA that shows the cell how to make a protein it needs.
What is the difference between a gene allele Chromosome and trait?
Alleles are alternate versions of genes that code for certain phenotypes, or traits. The traits of an individual are a result of the interaction between their genotype (alleles) and the environment.
How does the range of phenotypes for single gene traits different from the range for polygenic traits?
ABO Single gene trait blood group alleles on humans. That is the variation, not much, and not much recombination. 3! = 6. There is posited to be at least 7 alleles for height, which is a polygenic trait. Hypothetical alleles, SMYDKECV 7! = 5040 different combinations of alleles in height polygenic traits.
Two ways multiple alleles and polygenic traits differ?
Multiple alleles are "the existence of more than two alleles (versions of the gene) for a genetic traits. Polygenic traits are "[characteristics of organisms that are] influenced by several genes." So multiple alleles are more than two alleles for one trait, and polygenic traits are one trait that is influenced by multiple genes. This information came from my biology textbook, "Biology: Principles and Explorations" by Holt, Rinehart, and Winston.
What are non-mendelian trait?
Non-Mendelian traits are:A trait with no clearly dominant alleleA trait with four allelesA trait controlled by many genes
Can you explain how individuals with the same alleles for a specific trait are similar or different from those with different alleles for the same trait?
Individuals with the same alleles for a specific trait will have similar physical characteristics related to that trait. On the other hand, individuals with different alleles for the same trait will have varying physical characteristics. This is because alleles determine the expression of traits, and different alleles can lead to different outcomes in terms of physical appearance or other characteristics.
What type of traits is inherited if an organism receives recessive alleles?
The trait received is recessive.
What is one difference between single gene trait and a polygenic trait?
Polygenic traits result in more variation because so many more alleles are involved in the process of reproduction.
