How is math familiar with the punnett square?
Math is involved after you complete the punnett square because you find the phenotypic ratio, so that is numbers[while the genotype is letters with dominant and recessive gene alleles]. In the genotype part, you find the genotypic fractions of different matches out of the given number of crosses. For example, if you do four crosses with Aa and Aa in a punnett square, you will have 3/4 dominant A and 1/4 recessive a as the four crosses, which are the genotypic fractions. The phenotypic ratio is 1 dominant pair, 2 heterozygous, and 1 recessive pair, or 1:2:1.
What makes a dominant allele different from recessive Allie?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
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).
What trait is expressed when two different genes for the same trait are present is called?
It depends which one is the dominant gene, and which is recessive. Dominant always over rules recessive. I probably spelled recessive wrong so yeah... :P
What is the difference between incomplete dominance and codominance?
co dominance is when there is no dominant or reccessive traits just lie in in incomplete dominance the diffrence is in co dominance the are mkore chromosomes
How is a incomplete dominance different from a dominant and recessive relationship?
IT always varies on the X cromosomes

When one trait is not completely dominant over another?
This is called codominance in this case, neither allele is dominant over another, it creates in heterozyogous individuals a phenotype that is not in intermediate, nor the phenotype either of the two alleles create, but rather, a different phenotype.
Answers for Biology Corner Codominance and Incomplete Dominance worksheet?
1. In the fruit fly Drosophila melanogaster, vestigial wings and hairy body are produced by two recessive genes located on different chromosomes. The normal alleles, long wings and hairless body, are dominant. Give the genotype and phenotype of F1 progeny obtained from a cross between a vestigial-winged, hairy male and a normal, homozygous female. If the F1 from this cross are permitted to mate randomly among themselves, what phenotypic ratio would be expected in the F2generation?
What makes a dominant alleles different from a recessive alleles?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
What makes a dominant allele different from recessive Allie?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
What are the different forms of a gene either dominant or recessive?
heterozygous, homozygous dominant or homozygous recessive
What is it called when the presence of two different alleles results in intermediate phenotype?
Incomplete Dominance
What makes a dominant allel different from?
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
What is two dominant alleles called?
In eyes, it would be brown is dominant, and blue is recessive. Free earlobe allele is said to be dominant over the attached earlobe allele. When an organism has two dominant alleles for a trait, it is called homozygous dominant. Two recessive alleles for a trait is homozygous recessive.
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).

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).
Condition of being heterozygous for a recessive trait?
If you are heterozygous this means you carry both a dominant and recessive allele. if you are heterozygous for a recessive trait then you will have a dominant and recessive allele. example: let T represent tall and t represent short. a person with heterozygous for a recessive trait will have 'Tt'.
