In Tomatoes, the allele for red fruit is dominant over theallele for yellow fruit. If a plant that is homozygous for redfruit is crossed with a plant with yellow fruit â a) what is/arethe genotype(s) and the phenotype(s) of the fruit produced in theF1 generation? b) what is/are the genotype(s) and the phenotype(s)of the fruit produced in the F2 generation? c) what is thephenotypic ratio of the F2 fruit?

**2 questions, Can someone help explain the firstquestion. The second one, I just need someone to help see if I didit right.
Tomato Plants
In tomato plants, round fruit (R) is dominant to oval fruit(r). Pure breeding plants with red and round fruit(FFRR) were crossed to pure breeding plants with yellowand oval fruit (ffrr).
The red and round F1 progeny were then testcrossed toplants that were homozygous recessive for both genes(ffrr) with the following results:
| Phenotypes | Number of Offspring |
|---|---|
| Red and round | 2 255 |
| Red and oval | 290 |
| Yellow and round | 310 |
| Yellow and oval | 2 145 |
Complete a Punnett square to determine the expected testcrossprogeny on the basis of Mendelâs Law of Independent Assortment.
Tomato Plant Leaves
In tomatoes, regular leaves (L) are multilobed andserrated and potato leaves (l) are broad, smooth, andsingle (Image 1). Red fruit (F) is dominant toyellow fruit (f).
A cross is carried out between two pure lines of tomato plants,one having regular leaves and red fruit and the other having potatoleaves and yellow fruit. The F1 generation all haveregular leaves and red fruit. TheF1 individuals are then crossed with one another.
Complete a Punnett square to determine the expectedF2 progeny on the basis of Mendelâs Law of IndependentAssortment, which states that the alleles for one gene segregateindependently of the alleles for other genes during gameteformation.

Is my punnett square correct? If not, can someone explain
Genetics Suppose that the wild type phenotype for apples is yellow, short fruit with large leaves and that a strain of mutant apples has red, round fruit with small leaves. A and a represent the alleles for fruit color, B and b represent the alleles for fruit shape, and C and c the leaf shape. Two apples with the genotypes, Aa Bb cc and Aa Bb CC, are crossed. The resulting Punnett square is shown below. One square has been completed with the correct apple phenotype. Fill in the rest of the Punnett square by placing a fruit and leaf phenotype in each square.

What are the modes of inheritance for each trait in the mutant strain of apples?
