Given this information, select the statements that accurately reflect conclusions that can be made about the alleles for this trait. In order for a plant to have white flowers, it must inherit the allele for white flowers from both parents. A plant that has purple flowers can still carry an unexpressed allele for white flowers. The allele for white flowers is dominant to the allele for purple flowers. In order for a plant to have purple flowers, it must inherit the allele for purple flowers from both parents. The allele for purple flowers is dominant to the allele for white flowers

A botanist came across a species of plant that has two varieties of flower color: purple and white. The botanist wanted to complete several genetic crosses to determine the relationship between the two alleles. Upon crossing the different plants, the greatest majority of them were purple.

      The statements that accurately reflect conclusions about the alleles for flower color in this scenario are:

      1. In order for a plant to have white flowers, it must inherit the allele for white flowers from both parents.
      2. A plant that has purple flowers can still carry an unexpressed allele for white flowers.
      3. The allele for purple flowers is dominant to the allele for white flowers.

      Explanation:

      – The first statement is true because white flowers are only expressed when the plant has two recessive alleles for white (homozygous recessive).

      – The second statement is true as well; if purple is dominant, a plant with purple flowers could carry one allele for purple (dominant) and one for white (recessive), making it heterozygous.

      – The third statement is correct because, since the greatest majority of plants have purple flowers, it indicates that the purple allele is dominant over the white allele.

      The other two statements are incorrect because:

      – A plant does not need to inherit the purple allele from both parents to express purple flowers; it just needs one.

      – The allele for white flowers is recessive, not dominant.
