The genotype of the offspring with yellow pods is likely homozygous dominant (YY) or heterozygous (Yy), assuming yellow pods are dominant over green. The possible genotypes of the offspring with green pods would be homozygous recessive (yy), as green is the recessive trait. If both yellow-podded parents are heterozygous (Yy), some offspring could also be yellow (YY or Yy) while others could be green (yy).
This is one of the classic experiments carried out by Gregor Mendel. If you cross pure-breeding green pod plants with pure-breeding yellow pod plants the offspring (F1 generation) will all have green pods. This means that green pod is dominant and yellow pod is recessive. To explain the results, pure-breeding green pod plants must have the genotype GG (homozygous dominant) and yellow pod plants must be gg (homozygous recessive). When they are crossed the F1 offspring will receive a G allele from the green parent and a g allele from the yellow parent, so they will all have the genotype Gg ie they will be heterozygous.
Breaking it down:Hetero means different.Homo means same.Zygous refers to how similar two alleles are for a trait in an organism.Use:Heterozygous and homozygous are terms used to describe a cell determined on the status of its alleles for a trait.You would describe a cell as Homozygous when both alleles for a given trait are the same. (Genotype example: YY,yy)You would describe a cell as Heterozygous when both alleles for a given trait are different. (Genotype example: Yy)In use:A green sweet pea: Homozygous or Heterozygous?Taking my knowledge of sweet peas, the color green is recessive in sweet peas while the color yellow is dominant.Using your knowledge on recessive genotypes....(Hint: A pea with a genotype of Yy would be yellow... Bigger hint: To have a recessive trait you would need two alleles from a recessive trait that are the identical; genotype yy)Yep, you got it.A green sweet pea would be Homozygous.Why?Because the color green is a recessive trait in sweet peas. To have a recessive trait shown, the cell would have to have two identical alleles of that recessive trait.And what qualifies a cell as homozygous? When both alleles for a given trait are the same.BINGO!There you go.I hope this helps.~Monique G.9th gradeCA, USA
In pea plants, round seeds are dominant (R) over wrinkled seeds (r), and yellow seeds are also dominant (Y) over green seeds (y). A hybrid round pure yellow pea would have the genotype RrYY, where "Rr" indicates it is heterozygous for the round seed trait and "YY" indicates it is homozygous for the yellow seed trait.
The possible phenotypes of the offspring from a cross between yellow and red parental plants depend on the inheritance pattern of the traits. If yellow is dominant over red, the offspring could display either yellow or red phenotypes, with yellow being more prevalent. If the traits follow incomplete dominance, the offspring might show a blend of the two colors, resulting in orange. The exact phenotypic ratios would also depend on whether the parental plants are homozygous or heterozygous for their respective colors.
The phenotype (as I assume would be colour) for both homozygous and heterozygous yellow-grained corn is yellow.

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.
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!
yes because of there specific traits that they have from the outside like their fur color, eye color and etc....

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 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).
This is one of the classic experiments carried out by Gregor Mendel. If you cross pure-breeding green pod plants with pure-breeding yellow pod plants the offspring (F1 generation) will all have green pods. This means that green pod is dominant and yellow pod is recessive. To explain the results, pure-breeding green pod plants must have the genotype GG (homozygous dominant) and yellow pod plants must be gg (homozygous recessive). When they are crossed the F1 offspring will receive a G allele from the green parent and a g allele from the yellow parent, so they will all have the genotype Gg ie they will be heterozygous.
There would be four possible phenotypes: round yellow peas, round green peas, wrinkled yellow peas, and wrinkled green peas. This is due to the different combinations of alleles for seed shape (R for round, r for wrinkled) and seed color (Y for yellow, y for green) that can result from the cross.
The difference is that the black on is more powerful then the yellow.
The botanist could perform test crosses between the green-pod plant and a known homozygous recessive individual. If all offspring show the dominant green pod trait, the green-pod plant is likely homozygous. If the offspring display a mix of green and yellow pods, the green-pod plant is most likely heterozygous.
