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
Why is the IB allele dominant to the i allele?
The IB allele is considered dominant to the i allele because it produces a functional enzyme that adds the B antigen to the surface of red blood cells, while the i allele does not produce any antigen. This means that when both alleles are present (IBi), the B antigen is expressed, resulting in the phenotype associated with the IB allele. In contrast, the presence of the i allele does not affect the expression of the B antigen, making IB phenotypically dominant.
According to the principal of segregation What will the gametes of a heterozygous individual be?
According to the principle of segregation, a heterozygous individual (with one dominant allele and one recessive allele, such as Aa) will produce gametes that carry only one allele for each gene. In this case, the gametes will be either A or a, resulting from the separation of the alleles during meiosis. Therefore, half of the gametes will carry the dominant allele (A) and half will carry the recessive allele (a).
If a gene has one completely dominant allele and one recessive allele how many different traits can these alleles produce?
A gene with one completely dominant allele and one recessive allele can produce two different traits in a population. Individuals with two dominant alleles (homozygous dominant) and those with one dominant and one recessive allele (heterozygous) will exhibit the dominant trait, while only individuals with two recessive alleles (homozygous recessive) will display the recessive trait. Therefore, the two traits produced are the dominant trait and the recessive trait.
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.
A homozygous dominant parent will produce a gamete with?
They will produce gametes that are also homozygous.
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.
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.
What gametes can be formed by an individual with the genotype Aa?
An individual with the genotype Aa can produce two types of gametes: one carrying the A allele and one carrying the a allele. This individual will produce equal numbers of gametes with the A allele and gametes with the a allele due to Mendel's law of segregation.
Is it possible for AS blood group to produce AA?
No, it is not possible for an individual with the AS blood group to produce offspring with the AA blood group. The AS blood group indicates that the individual carries one A allele and one S allele (which is associated with sickle cell trait). For an offspring to have the AA blood group, both parents must provide an A allele, which cannot occur if one parent has an S allele.
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 two alleles could produce a trait controlled by a dominant allele?
Tt or TT
If a pea plant has a recessive allele for green peas what will it produce?
A recessive allele means that the gene codes for an nonfunctional enzyme. If the pea plant has 2 recessive allele for the green pea gene, that means that the green pigment will not be deposited on the peas, as the enzyme is nonfunctional. The result would be yellow coloured peas.If the pea plant has one recessive and one dominant allele for the green pea pigment, then it will result in a half functional enzyme, which is sufficient for the green pigment to be deposited.
