In what alleles can be observed in the phenotype?
you mean phenotype, and its dominant alleles
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
Are phenotype and genotype traits the same?
Phenotype and genotype traits don't always have to be the same. Phenotype is the physical characteristics and genotype is the genetic makeup. For example a pea plant can have the genotype of TT and look tall while another plant can have a genotype of Tt and also look tall (T= dominant trait; t= recessive trait.)
Another plant is said to be heterozygous for flower color what does this mean?
homozygous means that the alleles that make up the genotype are the same, for example homozygous dominant would have two dominant alleles (RR) or homozygous recessive would have two recessive alleles (rr). the alternative would be heterozygous, where the genotype contains both a dominant and a recessive allele (Rr). so a homozygous plant would either have two dominant alleles or two recessive alleles for the seed colour. Now the way to find out whether it is homozygous dominant or homozygous recessive is to do a cross with a homozygous recessive plant and look at the seed colour (the phenotype). if the the original genotype is homozygous dominant the offspring seed colour will show the dominant seed colour becasue it will be heterozygous. But if the original plant is homozygous recessive the offspring will show the recessive phenotype.
Which genotype represents a white-eyed male fruit fly?
A heterozygous genotype is always a capital letter, then a lowercase letter. Example: Hh
Do mutations affect phenotype or genotype?
genotype always...phenotype sometimes

If your husband and you have a positive why your baby is o positive?
f a husband and wife are are A positive and baby is O then it clearly depicts that both husband and wife are heterozygous and both have genotype "Ii and Ii" and as both have alleles "i" and when two "i alleles" combine they always result in blood group o having genotype iirida
Why is it difficult to determine the genotype of an organism that has a dominant phenotype?
NO, because a dominant phenotype could either be homozygous or a heterozygous.so unless you are sure about the genotype of parents we can't determine it...but we can determine the genotype of a person showing reccessive phenotype, as a recessive trait always expresses itself in a homozygous condition...
What is recessive gene and dominant gene?
A dominant gene is always expressed if present, and the recessive gene is only expressed with the homozygous recessive genotype. For example, if the dominant gene is red (represented by the letter R) and the recessive gene is white (represented by the letter r), then a homozygous dominant organism's genotype will be RR, and its phenotype will be red. If the organism is homozygous recessive, then the genotype will be rr and the phenotype will be white. If the organism is heterozygous, then the genotype will be Rr, and the organism will be red.
Organisms that are homozygous dominant and those that are for a trait controlled by simple dominance have the same phenotype?
Because the dominant gene always appears in the phenotype, whether or not it is "pure" (homozygous) or "mixed" (heterozygous). The recessive gene does what it says: it is recessive to the dominant gene. So, if it comes between the two, the dominant always appears. Of course, this only happens in your average Dominant-Recessive traits.
Are phenotype and genotype traits the same?
Phenotype and genotype traits don't always have to be the same. Phenotype is the physical characteristics and genotype is the genetic makeup. For example a pea plant can have the genotype of TT and look tall while another plant can have a genotype of Tt and also look tall (T= dominant trait; t= recessive trait.)
What alleles achieve expression?
Not quite sure what you mean by this question, but... the genotype is the written expression of the alleles and the phenotype is the physical characteristic. for example, let's say we're talking about red plants, and that the color red is dominant to the color white. The genotype of a red plant is either Rr or RR, but the phenotype is simply, "the plant is red." Also, the dominant allele is always expressed in the phenotype. In order for all white offspring to be produced, both parents must be white, because that is the recessive allele.
Another plant is said to be heterozygous for flower color what does this mean?
homozygous means that the alleles that make up the genotype are the same, for example homozygous dominant would have two dominant alleles (RR) or homozygous recessive would have two recessive alleles (rr). the alternative would be heterozygous, where the genotype contains both a dominant and a recessive allele (Rr). so a homozygous plant would either have two dominant alleles or two recessive alleles for the seed colour. Now the way to find out whether it is homozygous dominant or homozygous recessive is to do a cross with a homozygous recessive plant and look at the seed colour (the phenotype). if the the original genotype is homozygous dominant the offspring seed colour will show the dominant seed colour becasue it will be heterozygous. But if the original plant is homozygous recessive the offspring will show the recessive phenotype.
How can two plants that have different genotype have the same phenotype?
No they do not. Say for example we are looking at the the colour of pea plants where R represents the allele for the colour red and, and the other allele r represents green. The plant will be red with the genotype RR AND Rr which are different genotypes.
How would you write an allele that is heterozygous?
Representing heterozygote allele characteristics depends on the nature of the heterozygote.If one of the alleles is dominant, and the other recessive, the genotype is written as Aa - where the capital letter (A) represents the dominant allele, and the lower case letter (a) represents the recessive allele. The dominant (upper case) allele is always written first.However, the genotype cannot be written in this way if both alleles are codominant (neither one is dominant or recessive). In this case, the convention is to choose a letter to refer to the flower-color-locus as a whole. You would then add different superscript letters to denote the different alleles.For example, you could choose the letter A to refer to the flower-color-locus, and then choose C and D as the two co-dominant alleles. This genotype would be written as ACAD.
How can you have the same phenotype but different genotype?
Different genotypes don't always change your phenotypes because of mutations
