Read the paragraph from the section "Pea Plants And The Punnett Square." A pea plant could have one copy of the height gene that coded for "tall" and one copy of the height gene that coded for
"short." The tall allele is "dominant," and this means that it can mask the other allele. The short allele is called
"recessive." The allele combination of tall-short would result in a tall plant since the tall allele is dominant.
Which option is the BEST definition of the word "mask" as used in the paragraph above?
