What is the symbol for homozygous?
When a particular gene has identical alleles (versions) of chromosomes inherited from both parents, the gene is homozygous. A homozygous trait is referred to by two capital letters (XX) for a dominant trait, and two lowercase letters (xx) for a recessive trait.
What represents a homozygous dominant individual?
An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.
What is an example of homozygous?
Homozygous means that the organism has two copies of the same allele for a gene. … For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.
What symbol represents a heterozygous genotype?
|Bb||This symbol represents a heterozygous individual|
|bb||This symbol represents a homozygous recessive individual|
|Genetics||Branch of biology that studies traits and their inheritance|
|Heredity||the passing of traits from parents to their offspring|
What does heterozygous mean in genetics?
The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
Which of the following represents homozygous condition?
Hemizygous is a condition in which only one copy of a gene or DNA sequence is present in diploid cells. Males are hemizygous for most genes on sex chromosomes, having only one X and one Y chromosome.
What is the difference between a homozygous individual and a heterozygous individual?
Homozygous: You inherit the same version of the gene from each parent, so you have two matching genes. Heterozygous: You inherit a different version of a gene from each parent. They do not match.
What does homozygous mean in horses?
If a horse carries two copies of the same allele for a gene, he is homozygous (for instance, E/E or e/e, with the lowercase letters indicating recessive genes, and capital letters signifying dominant) for that trait. If he carries one dominant and one recessive allele, then he is heterozygous (E/e) for the trait.
