When the two haploid gametes contain two different alleles of a given gene the resulting offspring is called?
A heterozygote. An organism with the same alleles at a locus is called a "homozygot".
In fruit flies gray body color is dominant over black body color Suppose that a gray fruit fly heterozygous for the alleles for body color is crossed with one that has a black body What percentage?
50%
In fruit flies gray body color is dominant over black body color. Suppose two fruit flies heterozygous for the alleles that carry body color are crossed and 200 offspring are produced. How many would?
100 Black Bodies.
Scientists call an organism that has two different alleles for a trait is what?
an organism that has two different alleles for a trait is heterozygous
In a hardy-weinberg population with two alleles A and a that are in equilibrium the frequency of allele a is 0.1 what is the percentage of the population that is heterozygous for this alle?
34
How is sickle cell alleles maintained through natural selection?
Heterozygous induviduals pass the dominant and recessive alleles to offspring
When the two haploid gametes contain two different alleles of a given gene the resulting offspring is called?
A heterozygote. An organism with the same alleles at a locus is called a "homozygot".
How is the sickle cell maintained through natural selection?
Heterozygous individuals pass the dominant and recessive alleles to offspring.
How is the sickle allele maintained through natural selection?
Heterozygous individuals pass the dominant and recessive alleles to offspring.
Organism that has two diffrent alleles for a single trait?
An organism with two different alleles for a trait? is a hybrid
In fruit flies gray body color is dominant over black body color Suppose that a gray fruit fly heterozygous for the alleles for body color is crossed with one that has a black body What percentage?
50%
How would you describe the alleles in a heterozygous genotype?
A heterozygous genotype includes two different alleles.
What is the difference between purebred organism and a hybrid?
A purebred organism is the offspring of two homozygous parents, having either two dominant alleles, AA or two recessive alleles, aa. A hybrid is the offspring of two heterozygous parents, Aa.
How is the sickle cell allele maintained through natural selection?
Individuals with two recessive alleles have very high rates of reproduction.
What is a homozygous dominant offspring are?
Offspring that posses two different forms of the same gene. These are called alleles.
What does it mean if there is two different alleles for a trait?
The trait could show up in two different forms. Alleles are individual units that determine what trait will be expressed in an offspring. Alleles exist for most traits such as hair color or wing size. Having two alleles simply means that the trait can be expressed in different variation. One trait can have several different alleles.
How do you spell heterozygous?
That is the correct spelling of "heterozygous" (having variant alleles).
