Final answer:
With a Punnett square showing one homozygous dominant, two heterozygous, and one homozygous recessive, 75% of the offspring will display the dominant phenotype while 25% will show the recessive phenotype.
Step-by-step explanation:
In your given Punnett square, the genotypes are listed as homozygous dominant, heterozygous, homozygous recessive, and heterozygous. Considering these results, we can predict the phenotypic outcomes of the offspring. The homozygous dominant and heterozygous genotypes will express the dominant phenotype, while the homozygous recessive will express the recessive trait.
To calculate the proportion, we see that out of the four possible outcomes, three (one homozygous dominant and two heterozygous) will display the dominant phenotype and one (homozygous recessive) will display the recessive phenotype. Therefore, 75% of the offspring will have the dominant phenotype and 25% will have the recessive phenotype.
Note: This predicting calculation is a simple statistical probability based on the Punnett square and actual results can vary due to genetic recombination and other biological factors.
