In your Punnett Square activity, you chose beads which represented genes and used Punnett Squares to determine possible offspring.
your first parent genotype was yellow bead and blue bead and the
second parent genotype was blue bead and blue bead, how many
offspring our of 4 have the genotype yy?
please please

Two out of the four offspring will have the genotype yy.

explanation:

the sequence of amino acids in a protein determines its function. the dna sequence of a gene determines the amino acid sequence of the resulting protein. thus, any changes in dna sequence can result in changes in protein function. this is called a mutation.
