What is the dominance -recessive interaction of an allele pair?
This depends on the type of dominance relationship. You can have true dominance, in which case if the allele pair contains a dominant allele, the dominant trait will be expressed. In this case the recessive trait will only be exhibited if both alleles are recessive. A second case is that of codominance. In this case, two alleles are codominant, so if you have one of each, both traits will be expressed. A third case is that of incomplete dominance. In this case, if you have a dominant and a recessive allele, you will get a trait which is a mixture of both traits. A good example is when you breed a red flower and a blue flower and get a purple flower as progeny. Other things, like dominance series, also exist. However this information should answer your original question.
Why are sex-linked traits more conman in males?
Because males have XY configuration of sex chromosomes and females XX. So in xy situation even the recessive gene can express. That is why sex-linked characters in males are more common than females.
what is the second source of variation as offspring inherit chromosomes from each of their parents?
one allele
How one way in which a second allele for eye colour might be different?
A second allele for eye color might differ in its genetic sequence, leading to variations in the production of pigments. For instance, while one allele may result in brown eyes by promoting the production of melanin, another allele could lead to blue eyes by reducing melanin levels. This difference in pigmentation ultimately affects the visible color of the eyes.
What are the priciples of dominance?
A gene is composed of two alleles ( one from mom and one from dad ) and one of these alleles is " dominant " over the other in the expression of protein product and the " dominant " allele is seen in the phenotype.
What is The general term for an allele that masks the presence of another allele in the phenotype?
The general term for an allele that masks the presence of another allele in the phenotype is "dominant." Dominant alleles are expressed phenotypically when present, masking the effects of recessive alleles.
Is when one allele completely masks another?
This is called complete dominance, where one allele completely masks the expression of another allele in a heterozygous individual. The dominant allele is expressed phenotypically, while the recessive allele remains hidden.
What describes allele whose characteristic phenotype is masked by the presence of a second different allele?
Recessive
What describes an allele whose characteristics phenotype is masked by the presence of a second different allele?
Recessive

What is the significance of having only one allele for a given gene?
Having only one allele for a given gene means that there is no second copy of that gene present. This can be significant because it can lead to genetic disorders or traits being expressed more strongly, as there is no backup copy of the gene to compensate for any potential mutations or deficiencies.
Why a person with an allele for a particular trait may not have a phenotype that shows that trait?
An individual with a recessive allele for a trait may not exhibit the phenotype if they also have a dominant allele masking the expression of the recessive allele. This is known as the principle of dominance in genetics. The recessive allele will only be expressed phenotypically if an individual inherits two copies of that recessive allele.

What is 4 tenths of a second expressed as a fraction?
2/5 of a second.
What is expressed as joules per second?
Power is expressed as joules per second. It is a measure of the rate at which energy is transferred or converted.

one allele
