How do dominant and recessive alleles affect pheno type?
An allele can effect the phenotype of an organism by its dominance or recessiveness. If two dominant alleles are crossed the offsprings will carry the dominant trait of the alleles. If a dominant allele is crossed with recessive allele the phenotype of the offsprings will be of that of the dominant allele. And if two recessive alleles are crossed the phenotype of their offsprings will carry the reccesive trait.
How do you know if an allele is co-dominant?
An allele is a small piece of DNA responsible for some characteristic that plugs into a gene locus (or position) along a chromosome. Suppose the particular gene locus is responsible for flower colour in some plant. There may be alleles that plug in amongst the plant population for red or yellow flowers. Since chromosomes are paired, several combinations are possible. Both alleles may be red so the flower will be red and similarly for yellow. If there is a red allele and a yellow allele you may either get orange flowers but if one allele is dominant over the other the flower colour will be either red or yellow depending on which allele is dominant. If the red allele is dominant over the yellow there will be more red flowers. If it was only as simple as this three quarters of the flowers would be red and onequarter would be yellow. For two possible alleles with red dominant over yellow, there are four combinations:- R R Red flowers R Y Red flowers Y R Red flowers Y Y Yellow flowers
What Dominant alleles are both fully expressed in a phenotype?
The form of inheritance in which two (different) alleles are both expressed is called codominance. An example of codominance is the orange and black coat of a type of calico cat called a tortoiseshell. Both the orange allele and the black allele for coat color are expressed.
What is the difference between dominant and recessive gene?
There are no such things as dominant and recessive genes. There are only dominant and recessive alleles. Dominant alleles are parts of a gene that present its features over the recessive allele, which is the one that is always masked by the dominant allele. The recessive allele's trait only shows if both of the alleles in a trait are recessive.
What is the Sleepy Orange butterflies favorite flower?
an orange flower of coarse!
How does phenotype affect phenotype?
In codominance, in which an organism is heterozygous for a trait, both phenotypes are expressed equally because both alleles are dominant. An example is a tortoise shell cat. Tortoise shell cats have both black and orange fur because they have both a dominant black allele and a dominant orange allele for coat color. The black fur is expressed by the allele for black fur and the orange fur is expressed by the allele for orange fur.
What is a example of dominant?
A red flower and a yellow flower mating to produce an orange flower.
How do dominant and recessive alleles affect pheno type?
An allele can effect the phenotype of an organism by its dominance or recessiveness. If two dominant alleles are crossed the offsprings will carry the dominant trait of the alleles. If a dominant allele is crossed with recessive allele the phenotype of the offsprings will be of that of the dominant allele. And if two recessive alleles are crossed the phenotype of their offsprings will carry the reccesive trait.
What happens in co dominance inheritance?
both of the genotypes alleles mix and create a color for instance if a gene has two alleles and this gene is for a flower color and one allele is red and one white if there is co domminence the phenotype would be pink...
What type of dominance is demonstrated if a yellow bird and a red bird have an orange baby bird?
Incomplete dominance. Since neither gene is dominant over the other, both traits are shown, thus giving a combination of colors. The same thing happens when a red flower and white flower crossbreed and produce pink offspring--the genotype for color is equally dominant and combines an allele from both parents.

If you cross-pollinate an orange-flowering plant with a white-flowering plant and all the resulting flowers are orange you can conclude that?
The plant possesses a dominant gene that controls flower colour, for orange 'OO'. Also the white flower has the recessive form of the gene 'oo' All offspring have at least one of the dominant gene that makes them Orange also OO x oo | Oo Oo Oo Oo OO = Orange flower Oo = Orange Flower oo = White flower. The orange flower must have the double gene 'O' because if it didn't you would get white flowered offspring i.e. Oo x oo Would have resulted in | Oo Oo oo oo 2 Orange 2 White flowers

If an orange tiger gives birth to one white tiger and three orange tigers which allele does the mother have for color?
what does allele mean
When a purebred plant with red flowers is crossed with a purebred plant that has white flowers what will be the expected result assuming that flower color in this plant is a co dominant trait?
That depends on which color is dominant. If red is dominant, then F1 will all be red heterozygous. If orange is dominant, then same applies.
Is orange a flower?
Orange is not a flower but a fruit or a color. The End!
