What is difference between homozygous and heterozygous?
We all have two alleles, or versions, of each gene. Being homozygous for a particular gene means you inherited two identical versions. It’s the opposite of a heterozygous genotype, where the alleles are different. People who have recessive traits, like blue eyes or red hair, are always homozygous for that gene.
What is the difference between heterozygous and homozygous use an example?
A Homozygous individual carries a set of two identical (RR or rr) alleles while a Heterozygous individual bears different alleles (Rr). For example, let us consider the gene of the hair colour possessing two alleles, one allele code is responsible black (r) while the other allele code is responsible for black (R).
What is the difference between homozygous and homozygote?
⚡ Quick summary. An organism that has the same two copies of a gene is considered homozygous for that trait, while an organism that has different copies of a gene for a particular trait is considered heterozygous for that trait. In plant and animal breeding, such organisms can be called homozygotes and heterozygotes.
What’s the difference between genotype and phenotype?
Genotype versus phenotype. An organism’s genotype is the set of genes that it carries. An organism’s phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. … For example, differences in the genotypes can produce different phenotypes.
What is the difference between a dominant and recessive trait?
What is the difference between dominant and recessive traits? Dominant traits are always expressed when the connected allele is dominant, even if only one copy of the dominant trait exists. Recessive traits are expressed only if both the connected alleles are recessive.
What is heterozygous example?
If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair. The relationship between the two alleles affects which traits are expressed.
What is heterozygous and homozygous examples?
Homozygous means that the organism has two copies of the same allele for a gene. … Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white).
What are the differences between genes and alleles between homozygous and heterozygous conditions?
Homozygous: individual carries two alleles that are the same for a particular gene; heterozygous: individual carries two different alleles for a particular gene.
