Respuesta :
For this you are going to use S as the dominate and r for the recessive. Since both of the parents are squared eye the offspring's likely chance of having round eyes will be 0%.
Punnett square diagrammatically represents the hereditary of the alleles and the cross. When heterozygous two square-eyed pet mates, then there is a 25% chance that the offspring will be round-eyed.
What is Punnett square?
A Punnett square is a diagrammatical representation that helps in determining the genotype of the offspring by crossing the alleles of the parents.
The square-eyed pet being dominant with a heterozygous allele can be used to mate so that the offspring with round-eye is produced.
Here, the genotype of the square-eyed pet is Ss and the Punnett square is attached to the image below.
From the cross between Ss and Ss, it can be seen that there is a 25 % chance that the offspring produced will be round-eyed.
Therefore, 1/4 offspring will be round-eyed.
