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 is the phenotype of a female with two dominant alleles?
The phenotype of a female with two dominant alleles will express the traits associated with those dominant alleles. For example, if the dominant alleles are for a specific trait like flower color, she will display that dominant trait. Since dominant alleles mask the effects of recessive alleles, there will be no expression of any recessive traits associated with those genes. Overall, her phenotype will reflect the characteristics determined by the dominant alleles.
What is an organism that has two identical allies for a trait?
An organism that has two identical alleles for a trait is referred to as homozygous. For example, if a plant has two alleles for flower color that are both red (RR), it is homozygous for that trait. This genetic uniformity can influence the expression of traits, as both alleles contribute equally to the organism's phenotype.
What describe Organism that has two identical alleles for a particular trait?
An organism with two identical alleles for a particular trait is described as homozygous. This means that both alleles, inherited from each parent, are the same, whether they are dominant or recessive. For example, if an organism has two dominant alleles (AA) or two recessive alleles (aa) for a specific gene, it is considered homozygous for that trait. Homozygosity can influence the expression of traits and is important in genetics and breeding.
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 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.

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 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.
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.
What do scientists call it when you have two different alleles for a trait?
When an individual has two different alleles for a trait, it is referred to as being "heterozygous" for that trait. In contrast, if both alleles are the same, the individual is termed "homozygous." Heterozygosity can influence the expression of traits, particularly in cases involving dominant and recessive alleles.
