BRAINLIEST KITA PAG TAMA
͒ PUNNETT SQUARE ͒ ｡.ﾟ+
Problem to be solved: In peas, round seed shape (R) is dominant to wrinkled seed shape in and yellow seed color () is dominant to green seed color A pea plant which is homozygous round seed and has green seed color in crossed with pen plant that is heterozygous round sced shape and heterozygous yellow seed color
Directions:
1. Complete the steps in identifying the phenotypic and genotypic ratio using the Punnett square.
Step 1: Read and analyze the given problem
Step 2: RR or Rr - YY or Yy
Step 3: Parent's genotypes: 8 - RRyy x 2 - RrYy
Step 4: Possible gametes: Ry Ry Ry Ry x RY Ry TY ry Step
5: Fill up the Punnett square correctly.
Step 6: Determine genotypic and phenotypic ratios. Phenotypic ratio: -Genotypic ratio: % RRYy: % RrYy; % RRyy 96 Rryy
Gulde Questions:
1. List down the chances of the offspring being heterozygous for both seed shepe and seed color
2. What kind of cross is used to show how allelic pair of genes for a specific trait separates and recombines independently?

Answers & Comments
ANSWER:
Step 1. Analyze the problem
Round seed shape (R) is dominant to wrinkled seed (r)
Yellow seed color (Y) is dominant to green seed (y) PAYNE
Step 2. Determine the parent's genotype
parent 1 - RRYY
• Homozygous round (RR) .
• Homorygous green (YY)
Parent 2 - Arvy
• Heterozygous round (Rr)
• Heterozygous yellow (Y)
Cross genotype-RRYY XRrYy
MAAAY
JARAYNE
Step 3. Determine the possible gametes. (Use the FOIL method)
Parent 1 - R R Y Y
Therefore, the possible gametes for parent 1 are: RY, RY, RY, and RY
Parent 2 R r Y y
Therefore, the possible gametes for parent 2 are: RY, Ry, rv, and ry
Cross gametes = RY RY RY RY XRY Ry ry ry
