Some Plants Fail to Produce Chlorophyll, and This Trait Appears

question 55

Multiple Choice

• A) All will be green with chlorophyll since that is the dominant trait.
• B) All will be white and lack chlorophyll since this is self-pollinated.
• C) About one-half will be green and one-half white since that is the distribution of the genes in the parents.
• D) About one-fourth will be white and three-fourths green since it is similar to a monohybrid cross between heterozygotes.
• E) About one-fourth will be green and three-fourths white since it is similar to a monohybrid cross between heterozygotes.
