A moth has two alleles for spots. It can have brown and white spots. The white spot allele frequency is 0.53. What is the brown spot allele frequency?

How does codominance change the offsprings phenotype?
Codominance is contrary to typical mendelian genetics, in that no one allele is dominant to the other, so they are both expressed equally. The important part is that the offspring with express each allele independently, such as having spots of one color, then spots of another color, instead of blending the two colors, which would be incomplete dominance. So codominance changes the offsprings phenotype by making the offspring express both alleles equally, yet each allele's expression is separate/distinguishable, not blended.
Are giraffes orange with brown spots or brown with orange spots?
Which ever way you look at it you are most likely correct. Usually what i see is they are tan with brown spots.
A zebra population has a mutant allele for spots. The spot trait S is dominant to the striped allele s. what would the punnett square be if a spotted male mates with a striped female assuming that he?

What is incomplete and codominance?
Codominant alleles will both be expressed in the phenotype. So for example in the human ABO blood type, A and B are codominant. This means that a person with the alleles AB will have the characteristics of both A and B (they will have both A and B antigens on their blood cells). Another example of codominance - if B codes for black fur and b codes for white fur, an individual with Bb would have black and white spots/splotches/etc. Incomplete dominance is different in that the phenotype is a mix of the two. So for example, if B codes for black fur and b codes for white fur an individual with Bb would have grey fur (a mix of black and white).
When neither allele is dominant ( they blend)?
When neither allele is dominant, the trait that results depends on whether there is codominance or incomplete dominance. In codominance, that traits coded for by both alleles are expressed. For example, if R codes for red and r codes for white, a flower with the genotype Rr would be white with red spots/splotches/stripes/etc. (or red with white spots) - so it is showing both traits. In incomplete dominance - a mixture of the two traits is seen. For example, if R codes for red and r codes for white, a flower with the genotype Rr would be pink (a mixture of red a white).
What is a homozigouse?
It's spelt homozygous, which may explain the difficulty when you tried to look it up haha. I don't know your level of knowledge, but it refers to genetics. There are two alleles (allele = different type of a gene) at each locus (locus = physical location of a gene on a chromosome) on a chromosome. If these alleles are the same, they are considered homozygous. I'll give an example: we have a snake that either has spots or it doesn't, and spots is the dominant phenotype (phenotype = physically expressed trait). If it has spots, then it has the S allele, and if it doesn't have spots, it has the s allele (spots is uppercase and no spots is lowercase). If the organism does not have spots, then it is homozygous recessive with two s alleles (ss). If it had spots but had one S allele and one s allele (Ss) then it is heterozygous (two different alleles). If it had spots and had two S alleles (SS) then it is homozygous dominant. I hope that clarified.
What is codominant genotype?
When two alleles are codominant, that means that they are expressed simultaneously in different parts. For example, if a red and white flower were crossed, and the resulting flower had some red petals and some white petals that would be codominance. Another example is when animals have stripes and spots. Not to be confused in incomplete dominance, which is when two alleles are expressed simultaneously in the same part of the organism (in the flower example all the petals would be pink).

It is most likely not to have brown spots but if it does do not eat it.
What genes appear when genes are dominant?
Dominance in genetics is not a black-and-white thing. An allele may be dominant to one rival allele, but recessive to another. Ultimately, it may depend on the degree of functionality of the protein encoded by the allele. For instance, one allele may code for a non-functional protein, or not code at all. In that case, it would be recessive to any competing allele that did code for a functioning protein. Also, phenotypes are often the result of gene complexes - no single allele codes for a particular phenotypic trait, but many together do. The relationship between dominant and recessive alleles in such a complex may be equally complex: there may be degrees of expression along a sliding scale, or specific values for each dominance/recessiveness relation (eg. spots or no spots; green eyes, gray, brown or blue; curls or no curls, etc). See links below for more information.
What is incomplete dominance with examples?
A trait that exhibits incomplete dominance is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms.Here are some examples:A red and a yellow flower mating to produce an orange flowerA white cat and black cat having gray kittensA red flower and a yellow flower mating to produce an orange flower.
