How is each box inside a Punnett square filled in?
By combining its row allele with its column allele✓Richtige Antwort
By copying the genotype of the nearer parent straight into it
By writing the phenotype the offspring will show
By adding up the alleles in all four boxes
Erklärung
Every box stands for one fertilisation, joining a gamete from the top of the square with a gamete from the side, so it takes one allele from each direction. Copying a parent genotype into a box skips the fertilisation the square exists to model and would make every offspring a copy of a parent.
