Scientists compare two different plant species. In species A the leaf color is controlled by two alleles. In species B leaf color is controlled by five alleles. How will these two plants be different?
Species A will have fewer phenotypes. (apex)
The gene pool for a particular gene is?
a gene pool is the mixture of a group of a species' genes. like, if you took all of the DNA of a group of people, and mixed it all together, that would be a gene poolThe total of all alleles present in a population.All of the alleles in one population
An unlearned and fixed pattern of behavior common to all members of a species is called?
An unlearned and fixed pattern of behavior common to all members of a species is called a fixed action pattern. See http://www.answers.com/topic/fixed-action-pattern
What genes are a good example of multiple alleles?
The human ABO blood group system is a good example of multiple alleles. There are three alleles involved: IA, IB and IO. If a person inherits two IA alleles, or IA and IO, they will be group A. If they inherit two IB alleles, or IB and IO, they will be group B. If you inherit two IO alleles you will be group O.
Which two terms best describe the inheritance of human blood types?
codominance and multiple alleles
How is a species defined.?
By the fixed alleles in the species
How do you know that human height is not multiple alleles?
It is based on multiple alleles.
What has happens when an allele becomes fixed?
As alleles become fixed, there is an overall decline in heterozygosity as each population become homozygous for one or the other of the alleles.
Scientists compare two different plant species. In species A, the leaf color is controlled by two alleles. In species B, leaf color is controlled by five alleles. How will these two plants be different?
species B will have a wider range of phenotypes
Blood type in humans is controlled by which alleles?
Human blood type is determined by codominant alleles.
What is meant by the term human gene pool?
Biodiversity refers to the large number or variety of plants and animals in an ecosystem. A gene pool is the complete set of unique alleles in a species or population. So, when there is diversity in the gene pool, there is difference in the characteristics of species.
Scientists compare two different plant species. In species A the leaf color is controlled by two alleles. In species B leaf color is controlled by five alleles. How will these two plants be different?
Species A will have fewer phenotypes. (apex)
How many alleles are in the human body?
i dont know- but there are 23 pairs of alleles (including the xx or xy ones)
Why does the nucleus of a fruit fly contain less chromosomes than the nucleus of a human?
Every species has a fixed number of chromosomes in its nucleus so every species has a different chromosome number from the other.
What are some human traits that are caused by multiple alleles?
The heredity of the ABO blood groups are governed by multiple alleles.
How do multiple alleles control the trait?
In the case of multiple alleles, one trait is governed by more than two alleles. One example is the human ABO blood group. There are three alleles, A, B, and O. A person can, however, only inherit two of the three alleles.
Where do new species come from?
Generally when a species splits into two populations that are separated by some means that keeps the now individual gen pools from intermingling. This allows new alleles to arise in the separate populations and as time passes this frequency changes in alleles can give rise to new species.
