What are different versions of the same gene called?
Different versions of the same gene are called alleles. Alleles can differ in their DNA sequence, resulting in variations in the traits they encode for. These variations can lead to differences in an organism's phenotype.
When a pair of chromosomes contains different alleles for a trait that trait is called a what when a trait has two identical alleles it is called?
2 different alelles - heterozygous Same alelles - homozygous
What are organisms that have two different alleles?
When you have two identical alleles you are said to be homozygous for that particular trait. If the trait is dominant, then you are homozygous dominant. If the trait is recessive, then you are homozygous recessive.
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 are the Members of a gene pairs are identical?
When the members of a gene pair are identical, the organism is described as homozygous for that trait. This means both alleles, one inherited from each parent, are the same, whether they are dominant or recessive. Homozygosity can influence the expression of traits, as both alleles will produce the same phenotype. In contrast, if the alleles are different, the organism is heterozygous.
Having a pair of alleles the same is called?
A pair of alleles which are the same are said to be homozygous.
A fertilized egg with an unmatched pair of genes is said to be?
A fertilized egg with an unmatched pair of genes is called heterozygous. This means that the organism has two different alleles for a particular gene.
What term describes a pair of alleles that are the same?
Alleles that are the same = homozygous Alleles that are different = heterozygous
What are a pair of genes that are identical called?
A pair of genes that are identical are called alleles. Alleles are different forms of the same gene that occupy the same position on homologous chromosomes.
What is a gene pair called when is consist of two dominant alleles or two recessive alleles?
Homozygous
What are different versions of the same gene called?
Different versions of the same gene are called alleles. Alleles can differ in their DNA sequence, resulting in variations in the traits they encode for. These variations can lead to differences in an organism's phenotype.
When a pair of chromosomes contains different alleles for a trait that trait is called a what when a trait has two identical alleles it is called?

What are organisms that have two different alleles?
When you have two identical alleles you are said to be homozygous for that particular trait. If the trait is dominant, then you are homozygous dominant. If the trait is recessive, then you are homozygous recessive.
What are both inherited alleles called?
Genetic makeup formed from both inherited alleles together is called a genotype. Homozygous alleles would be a pair of identical alleles for a single trait. Heterozygous is different alleles for a single trait.
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 it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
Traits are determined by pairs of genes called?
The two chromosomes (two "X" shapes) that are in a pair are generally called "homologous chromosomes". A pair of "chromatids" make up the two arms of a single chromosome.
