Question: In fruit flies, straight wings are dominant and curly wings are recessive. what will the generations look like? assume that mendel’s method of crossing two true breeding parents with opposite traits is followed. check all that apply. the p generation has all straight wings. the p generation has straight wings and curly wings. the f1 generation has all straight wings. the f1 generation has all curly wings. the f1 generation has straight wings and curly wings. the f2 generation has all straight wings. the f2 generation has straight wings and curly wings.

If you are interested in genetics, you might have heard of the famous experiments of Gregor Mendel, the father of modern genetics. He studied how traits are inherited from one generation to the next using pea plants. He crossed two true breeding plants with opposite traits, such as tall and short, and observed the offspring. He repeated this process for several generations and discovered some patterns of inheritance.

One of his discoveries was the concept of dominant and recessive traits. A dominant trait is one that is expressed in the offspring even if only one parent has it. A recessive trait is one that is hidden unless both parents have it. For example, in pea plants, tall is dominant and short is recessive. If a tall plant and a short plant are crossed, all the offspring will be tall. But if two of these tall offspring are crossed, some of the next generation will be short.

We can apply the same logic to other organisms, such as fruit flies. Fruit flies have two types of wings: straight and curly. Straight wings are dominant and curly wings are recessive. What will the generations look like if we cross two true breeding fruit flies with opposite wing types? Assume that Mendel’s method of crossing two true breeding parents with opposite traits is followed.

To answer this question, we can use a tool called a Punnett square. A Punnett square is a diagram that shows the possible combinations of alleles (the versions of a gene) that can result from a cross. Each parent contributes one allele to each offspring. The allele for straight wings is represented by S and the allele for curly wings is represented by s.

The P generation (the parental generation) consists of two true breeding fruit flies: one with straight wings (SS) and one with curly wings (ss). We can write their genotypes (the combination of alleles they have) on the top and left side of the Punnett square.

|   | S | S |

|---|---|---|

| s |   |   |

| s |   |   |

The F1 generation (the first filial generation) consists of the offspring of the P generation. To fill in the Punnett square, we combine each allele from the top row with each allele from the left column.

|   | S | S |

|---|---|---|

| s | Ss| Ss|

| s | Ss| Ss|

The genotype of each F1 offspring is Ss, which means they have one allele for straight wings and one allele for curly wings. However, since straight wings are dominant, they will all have straight wings. The phenotype (the physical appearance) of the F1 generation is all straight wings.

The F2 generation (the second filial generation) consists of the offspring of the F1 generation. To obtain this generation, we cross two F1 fruit flies with each other. We can use another Punnett square to show the possible outcomes.

|   | S | s |

|---|---|---|

| S | SS| Ss|

| s | Ss| ss|

The genotype of each F2 offspring can be SS, Ss, or ss. The phenotype depends on the genotype. If the genotype is SS or Ss, the fruit fly will have straight wings. If the genotype is ss, the fruit fly will have curly wings.

Therefore, the answer to the question is:

- The P generation has all straight wings.

- The F1 generation has all straight wings.

- The F2 generation has straight wings and curly wings.

These are the correct options that you should check if you encounter this question in a quiz or a test.
