What is an organism that receives different alleles for a trait from each parent?
An organism that receives different alleles for a trait from each parent is called a heterozygote. This means that the individual has two different versions of a gene, one from each parent, which may result in a variety of different phenotypic outcomes.
How many alleles for a trait are passed down from each parent?
There are three common Blood type alleles: A, B, and O. We all have two alleles, one inherited from each parent. The possible combinations of the three alleles are: OO; AO; BO; AB; AA; BB.
How many alleles for one trait are normally found in the genotype of an organism?
An organism has two alleles for one trait. If the two alleles are the same, the individual is homozygous for that trait, and if they are different, the individual is heterozygous.
What are pure alleles?
Alleles come in pairs. Organisms inherit one allele from each parent organism with sexual reproduction. If the alleles are the same, they could be said to be pure alleles. The science term is monozygous.
The inherited combination of alleles is known as the offspring's?
The inherited combination of alleles is known as the offspring's genotype. It determines the genetic makeup of an individual based on the alleles inherited from each parent. The genotype influences the phenotype, or the observable traits of an organism.
Why does each parent organism in the f1 generation have four alleles listed in figure 6.17?
Each parent organism in the F1 generation has four alleles listed because they inherit two alleles from each of their two parents. This results in a total of four alleles, with each pair coming from the genetic contributions of the respective parents.
What is an organism that receives different alleles for a trait from each parent?
An organism that receives different alleles for a trait from each parent is called a heterozygote. This means that the individual has two different versions of a gene, one from each parent, which may result in a variety of different phenotypic outcomes.

How many alleles for one trait are normally found in the genotype of an organism?
An organism has two alleles for one trait. If the two alleles are the same, the individual is homozygous for that trait, and if they are different, the individual is heterozygous.
For each inherited characteristic an organism receives?
For each inherited characteristic an organism receives, there are two alleles, one from each parent. These alleles can be dominant or recessive, influencing the organism's traits. The combination of these alleles determines the phenotype, or observable characteristics, while the underlying genetic makeup is referred to as the genotype. This genetic variation is fundamental to the process of evolution and adaptation in populations.
Mendel's law of segregation states that an organism inherits two alleles for any given trait one from each parent?
Mendel's law of segregation states that each organism carries two alleles for a trait, one from each parent, and during gamete formation, these alleles segregate randomly into separate gametes. This results in each gamete carrying only one allele for a given trait.
What is another term for heterzygous?
Another term for heterozygous is "heterozygote." This term refers to an organism that has two different alleles for a specific gene, one inherited from each parent. In contrast, an organism with identical alleles for that gene is called homozygous.
What are alleles and how are they inherited from parent cells?
Alleles are alternative forms of a gene that can occupy the same position on a chromosome. When an organism inherits alleles from its parents, one allele is typically inherited from each parent. This process occurs during sexual reproduction, where each parent contributes one allele to the offspring.
What does it mean if an organism is homozygous?
An organism is considered homozygous when it has two identical alleles for a specific gene, one inherited from each parent. This means that both alleles express the same trait, whether dominant or recessive. For example, if an organism has two alleles for blue eyes (bb), it is homozygous for that trait. In contrast, heterozygous organisms possess two different alleles for a gene.
Organism that has two diffrent alleles for a single trait?
An organism that has two different alleles for a single trait is called heterozygous. This means that the organism inherited different versions of the gene responsible for that trait from each parent.
What Alleles are considered?
Alleles are different versions of a gene that arise due to variations in the DNA sequence. They can be dominant or recessive, influencing traits expressed in an organism. For example, an allele for brown eyes may be dominant over an allele for blue eyes. In a diploid organism, each individual carries two alleles for each gene, one inherited from each parent.
What determines an organisms alleles in sexual reproduction?
An organism's alleles in sexual reproduction are determined by the combination of alleles inherited from its two parents. Each parent contributes one allele for each gene, leading to genetic diversity in the offspring. Random assortment and recombination of alleles during meiosis further contribute to allele variation.
