Can a chromosome be homozygous?
When the loci in the matching chromosomes bear the same alleles, it is described as homozygous. It means that the alleles code for the same trait.
What is the difference between homologous chromosomes vs heterozygous chromosomes?
Homologous chromosomes have alleles on the same genes located in the same loci. Heterologous chromosomes have alleles on different genes.
What is a heterozygous chromosome?
Heterozygous refers to having inherited different forms of a particular gene from each parent. A heterozygous genotype stands in contrast to a homozygous genotype, where an individual inherits identical forms of a particular gene from each parent.
How are homozygous and heterozygous similar?
Homozygous — Differences & Similarities. Homozygous means two copies of the same allele, such as two dominant alleles. Heterozygous means one of each type of allele, one dominant and one recessive.
What is the difference between homozygous and homozygous?
Homozygous and heterozygous are terms that are used to describe allele pairs….Homozygous vs Heterozygous.
|It has two same copies of the same allele coding for a particular trait.
|It contains two different copies of alleles coding for a particular trait.
How are heterozygous and homozygous similar?
Homozygous means two copies of the same allele, such as two dominant alleles. Heterozygous means one of each type of allele, one dominant and one recessive.
How do you know if its heterozygous or homozygous?
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.
What is homozygous and heterozygous?
Heterozygous is the presence of different allele pairs at the same locus of the homologous chromosomes. That means both dominant and recessive alleles are present in the same individual.
What is the difference between homozygous and recessive chromosomes?
Homozygous-dominant chromosomes carry two copies of the allele that codes for the dominant trait whereas the homozygous-recessive chromosomes carry two copies of the allele that codes for the recessive trait. In homozygous organisms, the dominant trait is only expressed when both the chromosomes have a dominant gene at a similar locus.
What is a heterozygous allele?
Heterozygous is the presence of both dominant and recessive alleles in the allele pair, which determines a particular trait of a diploid organism. This situation can be represented as Xx. This means the two alleles in the pair are different from each other. The inheritance of the heterozygous alleles can occur in three ways.
How many phenotypes are possible with a homozygous condition?
Two different phenotypes are possible with dominant or recessive homozygous conditions. The phenotype is mostly due to the dominant allele in the heterozygous condition. Homozygous genotypes result in a single type of gamete. Heterozygous genotypes result in two different types of gametes.
