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.
2 different alelles - heterozygous Same alelles - homozygous
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.
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.
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.
A pair of alleles which are the same are said to be homozygous.
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.
Alleles that are the same = homozygous Alleles that are different = heterozygous
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.
Homozygous
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.
2 different alelles - heterozygous Same alelles - homozygous
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.
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.
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.
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.
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.
