And the pewnet square shown below the capital letters represents the blank form of the trait a dominant B recessive

It seems like you're referencing a Punnett square related to genetics, specifically regarding a trait where "B" represents the dominant allele and "b" represents the recessive allele. To create a Punnett square, you typically set up the alleles of the parents on the top and side of a grid to predict the offspring's genotype.

Here's a basic example:

  1. If both parents are homozygous dominant (BB), all offspring will be BB (100% dominant trait).
  2. If one parent is homozygous dominant (BB) and the other is homozygous recessive (bb), all offspring will be Bb (100% dominant trait).
  3. If both parents are heterozygous (Bb), the resulting Punnett square will produce:
    • 25% BB
    • 50% Bb
    • 25% bb

This would represent a 75% chance of the dominant trait being expressed in the offspring and a 25% chance of the recessive trait being expressed.
