Do all heterozygous pairs of allele produce an intermediate phenotype?
No
To produce the offspring each parent had to have at least one of what type of allele?
homozygous recessive
What is the only genotype that will produce O type of blood?
The gentotype is ii that will produce blood type O. The allele i is recessive, so both parents must have at least one i allele, and the child must be ii (double recessive) to be blood type O. The parents' blood types do not have to be type O- the genotypes Ai (blood type A, as A is dominant), and Bi (blood type B) can produce blood type O offspring, as long as the child inherits the i allele.
What phenotype is produced by AA genotype?
If A represents a dominant allele, then the AA genotype would produce the dominant phenotype.
What is the alternate form of a gene?
The answer is allele
If a pea plant has a allele for green peas it will produce?
green peas if it does not also have a dominant allele for yellow peas.
Can an organism with a Gg genotype produce gametes with either the dominant or recessive allele in equal amounts?
Yes. Remember that a heterozygote can produce two types of gametes. In this case, the unknown would produce gametes with the dominant allele A or the recessive allele a. The homozygous recessive would still only produce one kind gamete, with the recessive a allele. Therefore, we expect to see only two genotypes in the F1, Aa and aa, in equal proportions.
Do all heterozygous pairs of allele produce an intermediate phenotype?
No
If a pea plant has a recessive allele for green peas it will produce?
green peas if it does not also have a dominant allele for yellow peas.
What is recessivr allele?
For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent. An individual with one dominant and one recessive allele for a gene will have the dominant phenotype.
What two alleles could produce a trait controlled by a dominant allele?
Tt or TT
What is an allele that produce a trait in the heterozygous condition is?
homozygous
To produce the offspring each parent had to have at least one of what type of allele?
homozygous recessive
What combination of alleles could produce a trait controlled by a recessive allele?
recessive + recessive or tt
Can parents with O blood and B- blood produce a child with A blood?
No - this is not possible. The child must have one parent with an A allele in order to have type A blood. Neither of these parents have an A allele - so this is not possible.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What is a recessive allele?
Recessive allele is a trait that doesn't show in one's phenotype (observable trait) if there is a dominant allelle present. Only when you inherit a recessive allele from both parents (aa for example and not Aa) does the trait show in your phenotype.
