Diagramming a cross using a Punnett square
Punnett squares can be used to predict the two possible outcomes of the botanist’s test cross. The Punnett square on the left shows the predicted result if theunknown plant is homozygous (GG); the Punnett square on the right shows the predicted result if the unknown plant is heterozygous (Gg).
Drag the labels to the correct locations on the Punnett squares. (G is the symbol for the green-pod allele and g is the symbol for the yellow-pod allele.) You canuse a label once, more than once, or not at all.
Homework Answers
Homozygous green pod plant
Since it is a testcross that means that you are crossing different phenotypes or genotypes in order to determine which genes are recessive. This is so since you are crossing GG to gg to see if G is dominant to g. The answer is yes since all heterzygous have a green phenotype
The ratio is 1:0 since there is no yellow phenotype portrayed since it is overcome by the dominant G allele
Heterzygous green pod:
Due to crossing a heterzygous with a homozygous recessive. one gets a 1:1 ratio which means that tehre is equal probability of getting a yellow pod as there is getting a green pod

I’m so confused by this, please explain Punnett Squares Reginald Punnett was a British geneticist who developed the Punnett square to explain how the chromosomes of parents cross and produce offspring. In order to solve genetics problems using a Punnett square, it is necessary to a) understand the associated vocabulary and b) understand some of the rules for solving the problems. · Before you continue with the problems below, review the meaning of the terms allele, dominant, recessive, homozygous, heterozygous,...

Experimental technique: Reciprocal crosses
1)When Gregor Mendel conducted his genetic experiments with pea plants, he observed that a trait’s inheritance pattern was the same regardless of whether the trait was inherited from the maternal or paternal parent. Mendel made these observations by carrying out reciprocal crosses: For example, he first crossed a female plant homozygous for yellow seeds with a male plant homozygous for green seeds and then crossed a female plant homozygous for green seeds with a male plant homozygous for yellow seeds.Unlike...

Punnett Square Genotypic ratio: Phenotypic ratio: 5. Purple flowers (P) are completely dominant over white flowers (p). If a pea plant is heterozygous for purple flowers, can any of this plant's offspring have all purple flowers? Think about the different genotypes with which you can cross the hetero- zygous parent: homozygous dominant, heterozygous, and homozygous recessive. Use three Punnett squares to show your work for each possible phenotype. Heterozygous purple pea...

Experiment 1: Punnett Square Crosses Set up and complete Punnett squares for these crosses (remember Y = yellow, y = blue): YY and Yy YY and yy Answer these questions: What are the resulting phenotypes? All yellow Are there any blue kernels? No How can you tell whether or not there are blue kernels? This is because Yellow allele dominates and also it still shows up over the blue allele in the heterozygous chromosomes Set up and complete a Punnett...
