What combinations of alleles could produce a trait controlled by a recessive alleles?
recessive + recessive or tt
What type of individual can produce gametes with two different alleles?
An individual that can produce gametes with two different alleles is typically heterozygous for a particular gene, meaning it possesses two different alleles at that gene locus (e.g., Aa). During meiosis, these alleles segregate, allowing for the formation of gametes that carry either one allele or the other. As a result, such an individual can produce gametes with different genetic combinations.
Why do dominant alleles genes or traits always show up?
Dominant alleles express their traits even when only one copy is present, masking the effect of any recessive alleles. This occurs because dominant alleles typically produce functional proteins or traits that are observable, while recessive alleles may not produce a functional product or may only do so when two copies are present. As a result, dominant traits are more likely to show up in the phenotype of an organism.
How many different types of gametes can a heterozygous woman with two genes produce?
A heterozygous woman with two genes (each having two alleles) can produce four different types of gametes due to the random assortment of alleles during meiosis.
If a gene has one completely dominant allele and two recessive alleles how many different traits can these alleles produce?
A gene with one completely dominant allele and two recessive alleles can produce two different traits. The dominant allele will express its trait regardless of whether it is paired with another dominant or a recessive allele, while the two recessive alleles will express their trait only when paired together. Therefore, the possible combinations of alleles result in one dominant trait and one recessive trait.
What alleles always produce and effect?
Dominant alleles.
What combinations of alleles could produce a trait controlled by a recessive alleles?
recessive + recessive or tt
Do all heterozygous pairs of alleles produce an intermediate?
No
Is it possible for 2 alleles to produce 4 phenotypes?
yes
Is it possible for two alleles to produce four phenotype?
yes

How does incomplete dominance function at the molecular level?
One funcional allele is insufficient to produce the dominant pheontype. Both alleles are expressed as an intermediate of the alleles.
What is when a group of gene pairs acts together to produce a single trait?
alleles
What is it called when two alleles for a trait produce a mixed expression?
co-dominance
What are inactive alleles?
Inactive alleles are versions of a gene that do not produce a functional protein or have reduced activity due to mutations. These alleles may not contribute to the individual's phenotype or may have a diminished effect compared to active alleles. Inactive alleles can result in genetic disorders or variations in traits.
What two alleles could produce a trait controlled by a dominant allele?
Tt or TT
