Codominance is when an organism has two different dominant alleles, so both of them are expressed.

When an organism has two identical dominant alleles, it is homozygous.

Is Tt dominant?

in Tt it would be the big T as the more dominant one


What is the difference between dominant alleles and recessive alleles?

dominant-appears in first generation recessive-seems to dissapear


How does this influence the probability of the gamete receiving a dominant allele for pea shape?

If the dominant allele for pea shape is more prevalent in the population, then the probability of a gamete receiving a dominant allele for pea shape will be higher. The frequency of the dominant allele in the gene pool directly affects the likelihood of it being passed on to offspring through gametes during reproduction.


How do dominate traits over power the recessive?

Dominant traits are expressed over recessive traits because the dominant allele codes for a functional protein that masks the effects of the recessive allele. In a heterozygous individual carrying one dominant and one recessive allele, the dominant allele is expressed, leading to the dominant trait being observed.


What Dominant traits tend to be observed more frequently because?

Dominant traits tend to be observed more frequently because they only require one copy of the dominant allele to manifest in an individual, unlike recessive traits that require two copies. This means that if a dominant allele is present, it will express itself regardless of the other allele inherited. Additionally, dominant traits can often confer advantages in survival or reproduction, leading to higher frequencies of these traits in a population over time.

Would a recessive allele or dominant allele be more common in population?

Dominant allele because its more likely to be received by the next generation.


If and individual has one dominant allele and one recessive allele will the recessive allele show up?

No, the dominant allele will be expressed in the individual's phenotype, masking the presence of the recessive allele. The recessive allele will only be expressed if an individual inherits two copies of the recessive allele.

What makes dominant alleles different from recessive alleles?

It's in the word! Dominant means bigger or stronger or greater. So the dominant allele is the stronger gene that is going to show whereas the recessive allele is still in you, but is overshadowed by the dominant allele.


What is dominant the X or the Y?

An allele on either X or Y could be dominant over the allele on the other chromosome, but it is more common for the allele on the X to be dominant, because the Y chromosome is much smaller than the X and contains fewer genes. In many cases, there is no allele for a particular gene on the Y chromosome; so whatever allele is on the Y will be dominant.

What does The presence of an allele for purple flowers will mask the presence of an allele for white flowers mean?

Gene responsible for purple color is dominant over white color.

What is dominante allele mean?

a dominant allele is basically the one stronger, more powerful. unlike the recessive allele, i.e if two people wanted to calculate the probability of them having a baby with brown eyes, theyd have to look at their alleles, if the father had brown eyes, XX (to show how brown eyes are stronger) and the mother had hazel eyes (xx) their chid is going to have (Xx) which in this case, the child will have brown eys, because X is more dominant(strong) than x (recessive)


Would you expect there to be more children with the dominant phenotype or recessive phenotypewhy?

There would likely be more children with the dominant phenotype because it only requires one copy of the dominant allele to express the dominant trait, whereas the recessive phenotype requires two copies of the recessive allele.


What is the probability of obtaining a dominant phenotype from self-fertilization of a heterozygous individual is?

The probability of obtaining a dominant phenotype from self-fertilization of a heterozygous individual is 75%. This is because in a heterozygous individual, there is a 50% chance of passing on the dominant allele and a 50% chance of passing on the recessive allele. With self-fertilization, the possible combinations are: 1 dominant allele (25%), 2 dominant alleles (50%), and 1 recessive allele (25%). Dominant phenotype will be expressed if there are one or more dominant alleles present.
