What phenotype is produce by each of the following genotypes?
Genotype: AA - The phenotype is homozygous dominant, exhibiting the dominant trait. Genotype: Aa - The phenotype is heterozygous, exhibiting the dominant trait. Genotype: aa - The phenotype is homozygous recessive, exhibiting the recessive trait.
What is the genotype for a trait with a mixed pair of alleles?
PHENOTYPE = how the traitphysically shows-up in the organism. ...Heterozygous means one of each allele in the genotype (ex: Cc)
If a homozygous dominant plant crossed with a homozygous recessive plant what is the genotype and phenotype of their offspring?
If two homozygous plants with contrasting traits are crossed, the expected genotypes for the offspring will be heterozygous. The dominant trait would be expressed, but they'd be carriers for the recessive trait.
What phenotype is produced by AB genotype?
The genotype AA represents a homozygous dominant genotype. The capital letter "A" represents the dominant allele, while the lowercase letter "a" would represent the recessive allele. If both dominant alleles are present in a genotype (homozygous dominant) then the phenotype is "A" phenotype. If one dominant allele and one recessive allele are present (heterozygous dominant) then the phenotype is "A". Finally, if both recessive alleles "a" are present (homozygous recessive) then the phenotype is "a". Therefore, the answer to your question is the genotype AA would result in an "A" phenotype because the genotype is homozygous dominant.
A test cross made with a cat that may be heterozygous for a recessive trait what is the presumed genotype of the cat explain?
If the cat is suspected to be heterozygous for a recessive trait, the presumed genotype would be Aa, where A represents the dominant allele and a represents the recessive allele. This means the cat has one dominant allele and one recessive allele for the trait in question. The test cross would involve crossing this cat with a homozygous recessive individual to determine the genotype of the cat.

What Describes an individual that has two alleles for a trait?
It sounds like you are referring to homozygous vs heterozygous. If an organism has two identical alleles of the same gene, it is said to be homozygous. If an organism has two different alleles of the same gene, it is said to be heterozygous.If a homozygous organism has two identical dominantalleles, it is said to be homozygous dominant, while an organism with two identical recessive alleles is said to be homozygous recessive.If this was not what you're asking, please clarify your question on the discussion page so someone can Terms_that_describe_two_alleles_of_the_same_genethis answer.
What genotype will all the offspring have?
That depends. Are the parents both homozygous dominant for the dominant genes for a particular trait or are they heterozygous and homozygous(dominant or recessive). See you have to be more picky about the questions you ask. A badly asked question gets a very sophisticated and complicated response to counteract the false accusations of ones troubled question asking skills. That good enough for ya.
What is the phenotype of a homozygous dominant person?
Homozygous dominant- means having dominant alleles at the same locus on a chromosome.More correctly, it's the same locus on two chromosomes (a homologous pair).
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 an organism with 2 alleles for 1 trait that are different?
The answer to your question, "What is an organism with 2 of the same alleles for a trait called?" is homozygous. it is just homozygous-By SciienceFreak
How can you do a genetic cross to identify the P genotype?
The genotype of the P (parent) generation can be done by crossing an offspring from the F1 (first filial) generation with one of the gametes from the P generation and then calculating the genotypic and phenotypic ratios. Such an experiment is called a back cross
Is a recessive gene expressed?
Ok, im assuming your question is "if two recessive alleles are present will the trait be expressed" A trait will be expressed if two alleles are recessive but it will not be the same representation as two dominant alleles. For example, T being a tall pea plant and t being a small pea plant. Two recessive alleles or, homozygous recessive, alleles The other option would be there is one dominant and one recessive, heterozygous, which would look like Tt. This would take on the trait of the dominant allele usually expressed by the capital letter. So this heterozygous plant would be tall.
