How can two plants have different genotypes having the same phenotype?
The simplest way that two plants can have different genotypes, but the same phenotype, is if they both have a dominant allele for the same trait. For example, the genotypes Pp and PP, will both produce the phenotype created by P (for example, pink coloured petals). This is because P is dominant to p, and will always be expressed. Other ways that the same phenotype can be created from different genotypes are when the environment affects the traits, or when the trait is controlled by more than one gene.
What are the 8 different blood types?
the six different blood types are AB, AA or AO, BB or BO, OOAB, AA, AO, BB, BO, and OO"The allels for blood types are called A,B, and O. The O allele is recessive to both the A and B alleles. When a person inherits one A allele and one B allele for blood type, both are expressed-phenotype AB. A person with phenotype A blood has the genetic makeup, or genotype BB or BO. Finally, a person with phenotype O blood has the genotype OO"There are actually more than six blood types. There are 30 different recognized systems, each of which has multiple types (at least two, sometimes more).
Why natural selection acts on the phenotype rather than genotype?
natural selection is a passive prosess . the mechanism of some individuals to be selected more than others is because they fit their environment more. and phenotype shows the fitness .
Why does natural selection only work on phenotypes?
Natural selection is based on the environment and on the traits of organisms. Organisms with more suitable traits are more likely to survive until reproductive age, while organisms with less suitable traits are more likely to die before they can reproduce. Most of these traits are genetic traits. The phenotype is the set of all genetic traits. Natural selection is not determined by genotypes, because genotypes are merely an organism's genetic makeup. Only the dominant or somewhat dominant alleles in the genotype will also appear in the phenotype. However, genotypes still contribute to natural selection indirectly in that two alleles in two parents' genotypes which had not appeared in their phenotypes could be inherited such that they are in the phenotype of the offspring.
Why isn't it possible to have more genotypes than phenotypes?
I think you have the question backwards, "Why isn't it possible to have more phenotypes than genotypes?" There are always more or an equal number of genotypes relative to phenotypes. The phenotype for a simple dominant/recessive interaction (for example) T for tall and t for short where TT is tall, Tt is tall and tt is short has three genotypes and two phenotypes. If T and t are co-dominant then TT would be tall, Tt would be intermediate and tt would be short. (Three phenotypes and three genotypes.)
Which genotypes have dominant phenotypes?
The genotypes in which one or more alleles is dominant.
If one parent has a blood of b negative and the other o positive?
The child's blood could be B+, B-, O+ or O- depending partly on the exact genotypes of the parents and partly on random chance.You might want to have a look at this answer in Answers.com for more details. It explains all about blood types and their genetics.What_happens_if_both_parents_of_a_child_are_A_negative
Is one blood group more dominant than another?
Genotypes, Phenotypes, and frequencies in the ABO blood-typing systemGenotype Blood Type A Antigen present B Antigen Present Frequency exampleIAIA or IAi A + - 41IBIB or IBi B - + 11IAIB AB + + 4ii O - - 44Among the six possible genotypes, there are four distinguishable phenotypes- the A,B,AB and O blood types. In this system, the IA and IB alleles are codominan, since each is expressed equally in the IA IB heterozygotes, and the i allele is recessive to both the IA IBalleles.Principles of Gentics Snustad.Simmons
What are multiple-allele traits?
Traits governed by multiple alleles are controlled by three or more alleles, rather than two. An example in humans is the ABO blood group system. There are three alleles in the ABO blood group system, IA, IB, IO. These three alleles can produce six genotypes, AA, AO, BB, BO, AB, OO. These genotypes can produce four different phenotypes, A (genotypes AA or AO), B (genotypes BB or BO), AB, (genotype AB) and O (genotype OO).
What diseases are common to specific blood types?
Malaria is one disease that is more prevelant in certain blood types than others. Another disease more prevelant is certain blood types would be cancer.
What are multiple allele traits?
A polygenic trait that require the additive effects of many alleles to be expressed. Height is an example of a polygenic trait. Or, a trait that has many alleles to fill the loci on chromosomes. Blood types are examples of this. A, B and O are all alleles that git the two chromosomal loci, but only any two at once whether homozygous or heterozygous.
What blood type will the baby have if both parents have different blood types?
The baby will have some combination of the parents blood types. Without more information I cannot give you more specific info.
