To answer your questions, we need to make some assumptions about the genotypes involved because the Punnett square you mentioned is not visible. However, I can provide a general explanation based on typical genetic inheritance patterns.
Question 1:
If "A" represents small petals (which is dominant) and "a" represents large petals (which is recessive), then the possible combinations from a typical Punnett square would be:
- AA (small petals)
- Aa (small petals)
- Aa (small petals)
- aa (large petals)
From this, you can see that out of 4 offspring, 3 have small petals (AA or Aa) and 1 has large petals (aa). Therefore, 25% of the offspring would have large petals.
Answer: 25%
Question 2:
If all of the offspring have small petals, this indicates that the dominant trait (small petals) is expressed in all offspring, which shows complete dominance of the small petal allele (A) over the large petal allele (a).
Answer: Complete dominance
