Ayellow pea plant (yy) and a green pea plant (yy) could not produce green offspring. true or false?

The given statement is False.

Explanation-

Yellow pea plant is a dominant trait ( represented by Y allele) over the green pea plant ( that is represented by y allele), which is a recessive trait. Green pea plant will be produced only when both the alleles are recessive that is with the genotype yy.

As per the question, genotypes of parents are Yy and yy. When they are crossed, they will produce 50% green pea plant. Refer punnett square.

the dna molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. power is turned on and dna fragments migrate through gel (towards the positive electrode).
