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.
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
Mix the homozygous dominant with a homozygous recessive, and you will get a purebred!

120 on average or 50%. 25% would be homozygous dominant and 25% would be homozygous recessive. The remaining 50% would be heterozygous.

75% because the recessive and dominant genes are corresponding and in a Punnett square it takes over.
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
If they're both homozygous (AA, AA): A is produced. If they're both heterozygous (Ai, Ai): A or O is produced. If one of them is heterozygous and the other not (Ai, AA): A is produced.
Mix the homozygous dominant with a homozygous recessive, and you will get a purebred!
Heterozygous - White gene carrier Homozygous - No white gene White tigers are not albinos and do not constitute a separate subspecies of their own and can breed with orange ones, although all of the resulting offspring will be heterozygous for the recessive white gene, and their fur will be orange. The only exception would be if the orange parent was itself already a heterozygous tiger, which would give each cub a 50% chance of being either double-recessive white or heterozygous orange. If two heterozygous tigers, or heterozygotes, breed on average 25% of their offspring will be white, 50% will be heterozygous orange (white gene carriers) and 25% will be homozygous orange, with no white genes. In the 1970s a pair of heterozygous orange tigers named Sashi and Ravi produced 13 cubs in Alipore Zoo, of which 3 were white. If two white tigers breed, 100% of their cubs will be homozygous white tigers. A tiger which is homozygous for the white gene may also be heterozygous or homozygous for many different genes. The question of whether a tiger is heterozygous (a heterozygote) or homozygous (a homozygote) depends on the context of which gene is being discussed. Inbreeding promotes homozygosity and has been used as a strategy to produce white tigers. (From Wikipedia)
The trait that would be expressed in a heterozygous genotype would be the dominant trait. If one allele is dominant then it will be expressed.

homozygousHomozygousit means homozygous. if both alleles are recessive, the trait will be homozygous recessive. if both alleles are dominant, then the trait is homozygous dominant.An allele is a letter representing the alternative forms of a gene. In most cases, there will be a dominative allele, written as the capital letter (in this case, H, although the allele can be any letter), and there will be a recessive allele, written as the lowercase of the same letter as the dominative allele for that particular trait (h).These alleles can be homozygous (both the same, such as in a purebreed) eg HH or hh. On the other hand, they can also be heterozygous, meaning that the gene has one dominative allele, and one recessive allele. This is written as Hh.When something that is homozygous (either homozygous dominant, HH, or recessive, hh,) is bred with another homozygous that is the same, the offspring will have two identical alleles. For example, a plant that is homozygous with the alleles HH to produce the trait of red flowers, is pollinated by another plant, also homozygous HH for the trait of red flowers. The offspring will also have the homozygous alleles HH and will be a pure bred for red flowers.Such is the case for anything. If a gene has two alleles that are identical, it will be purebred for that particular trait produced by those alleles.homozygousIs homozygousl.homozygoushomozygous
