What is the difference between homozygous and heterozygous organism?
if for example we had a yellow and a blue flower yellow being dominant (Y) and blue being recessive (y) a homozygous organism has the phenotype of either being YY or yy and a heterozygous organism could only be Yy.
What is the difference between homozygous yellow peas and heterozygous yellow peas?
Homozygous yellow peas have two identical alleles for yellow color (YY), while heterozygous yellow peas have one yellow allele and one non-yellow allele (Yy). This means that homozygous yellow peas will always produce yellow offspring when crossed, while heterozygous yellow peas have a 50% chance of producing non-yellow offspring when crossed with another heterozygous pea plant.
In pea plants the peas produced may be green or yellow with yellow being the dominant form of the allele. What would be the phenotype of a pea plant that is heterozygous for the alleles?
yellow peas
If a pea plant that is heterozygous for round yellow peas (RrYy) is crossed with a pea plant that is homozygous for round peas but heterozygous for yellow peas (RRYy) how many different phenotypes are?

If you see a healthy living yellow mouse can you tell if it is heterozygous or homozygous?
yes because of there specific traits that they have from the outside like their fur color, eye color and etc....
In pea plants the peas produced may be green or yellow with yellow being the dominant form of the allele . What would be the phenotype of the pea plant that is heterozygous for the alleles?
yellow peas
If the allele for yellow peas is dominant to the allele for green peas what experiment do you do to find out if the yellow peas are homozygous dominant or heterozygous?
You will need to place the genetic combination possibilities into at least two Punnett Squares where Y=dominant yellow and g=recessive green symbols are assigned . Observe the outcome of the crosses which should reflect a specific probablity of results shown as follows: YY X gg yields 100% Yg heterozygous combinations with yellow appearance and could be dominant but further experimentation is needed to confirm. Yg X gg yields 50% heterozygous offspring (yellow appearance) with 50% homozygous (green appearance). If other results are observed after these two genetic combinations then yellow is not dominant to green. Lastly comparing the results between the two crosses will help you narrow the distinction between homozygous and heterozygous characteristics. Research: Punnett Squares further if you are not familiar with its dynamics. Good luck!

What will the colors of the offspring of a heterozygous yellow and green pea plant?
In pea plants, the yellow color (Y) is typically dominant over the green color (y). If a heterozygous yellow pea plant (Yy) is crossed with a green pea plant (yy), the possible genotypes of the offspring would be 50% heterozygous yellow (Yy) and 50% homozygous green (yy). Therefore, the offspring would exhibit a 50% chance of being yellow and a 50% chance of being green.
When two pea plants that are heterozygous for yellow peas are crossed.the resulting offspring have a genotypic ratio of?
Because heterozygous means that the parents contain both dominant and recessive genes the offspring will be 75% tall and 25% short. If you were to draw the punnett squares you would see that there are 3 possible children one with only dominant tall traits two with both dominant and recessive traits and one with only recessive traits.
If Genotype of a G as dominate green and g for recessive yellow what would the heterozygous look like?
The heterozygous genotype would be Gg. This means the individual has one dominant green allele (G) and one recessive yellow allele (g). The dominant trait (green in this case) would be expressed in the phenotype of the individual.
In peas the color yellow (Y) is dominant to the color green (y). Use a Punnett square to determine the cross of two heterozygous parents. What are the resulting genotypes?
When crossing two heterozygous pea plants (Yy x Yy) using a Punnett square, the resulting genotypes are YY, Yy, Yy, and yy. This results in a 1:2:1 genotype ratio, where 25% of the offspring will be homozygous dominant (YY), 50% will be heterozygous (Yy), and 25% will be homozygous recessive (yy). The phenotypic ratio will be 3 yellow (YY and Yy) to 1 green (yy).
