No they do not. Say for example we are looking at the the colour of pea plants where R represents the allele for the colour red and, and the other allele r represents green. The plant will be red with the genotype RR AND Rr which are different genotypes.
False. Any living thing depends on the alleles from both parents. Crossing a hybrid tall plant (Tt) with a recessive short plant (tt) could end up with 50% tall and 50% short. The dominant allele (the capital genotype) will usually decide the majority of the off springs alleles. The dominant could be decided by either the same genotype, for example, TT, or a hybrid, Tt. A recessive could only occur with the same recessive alleles, tt.
a true breeding plant always produces offspring with the same trait as the parent(s).
There are a couple of reasons that two plants that have different genotypes can have the same phenotype. Heterogeneous and homogeneous genotypes can produce the same phenotype.
No, two plants may have the phenotype of the dominant gene, but one plant could be homozygous dominant and the other could be heterozygous. So that would make their genotypes different.
Coevolution.
One way is if an allele for the gene in question is dominant. Homozygotes for the dominant allele and heterozygotes will both have the same phenotype.Organisms have the same phenotype, or physical characteristics. They do not, however, have the same genotype, or genetic makeup. If T represent tall, and t represnts short then the organism will have the genotypes TT and Tt. If you make a Punnett square you will have the same phenotype but different genotypes. Unless some weird mutation occurs....
Dominant alleles are expressed, even if a recessive allele is also present. In the notation used, a capital letter means a dominant allele - therefore the presence of a P (in either PP or Pp) means the organism will display the trait P creates.
The question should be "If two alleles for a gene are the same, what phenotype will the organism have?" Answer: If the two alleles are for the dominant phenotype, the organism will exhibit the dominant phenotype. If the two alleles are for the recessive phenotype, the organism will have the recessive phenotype.
Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.
Homozygous dominant- means having dominant alleles at the same locus on a chromosome.More correctly, it's the same locus on two chromosomes (a homologous pair).
yes
The genotype of the offspring that had the same phenotype as the parents is rr or wrinkled. The phenotype for the seed shape of both parent plants is round.
well GG and Gg both produce the same phenotype for a trait GG and Gg are both different kinds of genotypes that make the same phenotype
Nope! TT is the dominant phenotype (what ever it may be) and tt is the recessive phenotype (what ever that may be).So say T is the allele for Tall plants, t is the allele for short plants. TT would be show the tall phenotype while tt would show the short phenotype. If the genotype was Tt, the phenotype would be tall as well because the T is dominant and masks the phenotype of t (short plants).
You look at the offspring. Offspring of a heterogenous match are going to have different phenotype percentages than those of a homogenous match.
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.
Different genotypes don't always change your phenotypes because of mutations

Homozygotes for the dominant allele and heterozygotes will both have the same phenotype.Organisms have the same phenotype, or physical characteristics.

Phenotype and genotype traits don't always have to be the same. Phenotype is the physical characteristics and genotype is the genetic makeup. For example a pea plant can have the genotype of TT and look tall while another plant can have a genotype of Tt and also look tall (T= dominant trait; t= recessive trait.)
Phenotype. The physical expressed characteristics of an organisms genotype is known as its phenotype. Two organisms may have the same phenotype, but different genotype depending on the dominate or recessive genes present. Just remember physical=pheno.
it is possible beccause you dont always need both
