Yes.
If
* two or more organisms are formed from the same original cell, and
* all divisions of that cell are by mitosis, and * there is no mutation, then the organisms will be genetically identical (= have the same genotype).
Some examples:
* human identical (monozygotic) twins * individuals of Hydra, a freshwater coelenterate, formed by budding * plants formed by vegetative propagation, such as budding (e.g. fruit trees in horticulture) and forming stolons (e.g. strawberries naturally)
Yes, in a homozygous genotype, two alleles are the same.
Organisms or genotypes that are homozygous for a specific trait and always produce offspring of the same phenotype are said to be true breeding. This means that when bred with another organism of the same genotype for that trait, all offspring will display the same characteristic.
One can determine whether a genotype is heterozygous or homozygous by looking at the alleles present. If there are two different alleles for a particular gene, the genotype is heterozygous. If there are two of the same alleles, the genotype is homozygous.
An organism's genotype refers to the specific set of genes it carries in its DNA. It is the genetic blueprint that determines the organism's characteristics and traits. A genotype is unique to each individual and can influence how traits are expressed.
An example of a haploid genotype in organisms is the gametes, such as sperm and egg cells, which contain only one set of chromosomes.
Yes,if one has two dominant alleles and other has a dominant and a recessive allele
No. It is possible for the reverse to be true, two organisms can have the same phenotype but a different genotype. This is because the phenotype is what you will see on the outside whereas the genotype is the combination of alleles and since this determines the phenotype, two organisms with the same genotype will have the same phenotype. So, basically, no. Actually 2 organisms can certainly have different phenotypes with the same genotype--this refers to the concept of penetrance. Some people can have the gene for a condition but never show symptoms. An excellent example of this is the disease neurofibromatosis. This disease has very variable penetrance in which a child of an affected parent may show no signs of the disease, but then have a child with a severe form.
Yes, in a homozygous genotype, two alleles are the same.
A biotype is a group of organisms sharing the same specific genotype.
Although organisms with the same physical characteristics have the same PHENOTYPE, they might have different GENOTYPE, or genetic makeup.
genotype
Organisms or genotypes that are homozygous for a specific trait and always produce offspring of the same phenotype are said to be true breeding. This means that when bred with another organism of the same genotype for that trait, all offspring will display the same characteristic.
A homozygous recessive genotype can be identified when an individual has two copies of the recessive allele for a particular gene. This means that both alleles for that gene are the same and are both the recessive form. This genotype will typically show the recessive trait associated with that allele.
two capital or two lowercase letters in the GENOTYPE (ex: TT or tt) it's also called HOMOZYGOUS.
One can determine whether a genotype is heterozygous or homozygous by looking at the alleles present. If there are two different alleles for a particular gene, the genotype is heterozygous. If there are two of the same alleles, the genotype is homozygous.
