Answer:
phenotypic: Gg 100% heterozygous dominant (green pod)
Explanation:
GG (green pod)x gg(yellow pod)
G G
g. Gg. Gg
g. Gg. Gg
genotypic:100%
phenotypic 100%
Explanation:
In order to determine the probable phenotypic ratios in the offspring resulting from the cross between a plant with green pods and a plant with yellow pods, we need to consider the concept of dominant and recessive traits.
Dominant traits are those that are expressed in the presence of at least one copy of their corresponding allele. In genetic notation, dominant traits are usually represented by capital letters. Recessive traits, on the other hand, are only expressed when an individual has two copies of the corresponding recessive allele. Recessive traits are typically represented by lowercase letters.
Let's assign the letter "G" to represent the allele for green pods (dominant trait) and the letter "g" to represent the allele for yellow pods (recessive trait).
To determine the probable phenotypic ratios in the offspring, we can use a Punnett square. Here's how you can set up the Punnett square step by step:
Step 1: Write down the genotypes of the parents:
Plant with green pods: GG (homozygous dominant)
Plant with yellow pods: gg (homozygous recessive)
Step 2: Represent the alleles in each parent's gametes (sex cells):
Plant with green pods (GG): G
Plant with yellow pods (gg): g
Step 3: Create a Punnett square by combining the alleles from each parent:
Step 4: Determine the genotypes of the offspring:
In the Punnett square above, all the possible combinations are "Gg," which means the genotype of all offspring will be heterozygous dominant for green pods.
Step 5: Determine the phenotypes of the offspring:
The genotype "Gg" represents the dominant trait for green pods, so all the offspring will have green pods.
Step 6: Calculate the phenotypic ratios:
Since all the offspring will have green pods, the phenotypic ratio will be 100% green pods.
Therefore, the probable phenotypic ratio in the offspring resulting from this cross is 100% green pods.
