Question

question 4
youre conducting a science experiment crossing two different purebred mouse strains, which each contain a different variation of the same gene, for two generations. what do you expect to see as the phenotypes of the first generation? what about the second generation?

question 5
how closely do mendels insights into dominant and recessive traits match up with the ratios that punnett calculated in his punnett squares?

Explanation:

For Question 4, in genetics, when crossing pure - bred strains with different gene variations, the first generation (F1) will show the dominant phenotype according to Mendelian genetics. In the second generation (F2), a 3:1 phenotypic ratio of dominant to recessive traits is expected. For Question 5, Mendel's insights into dominant and recessive traits closely match the ratios calculated in Punnett squares as Punnett squares are a graphical representation of Mendel's laws of inheritance.

Answer:

Question 4: First generation: Dominant phenotype. Second generation: 3:1 phenotypic ratio of dominant to recessive traits.
Question 5: They closely match.
