Question

You have two plants, one with blue flowers and one with white flowers. You know that white is recessive. From a cross, you get four progeny with blue flowers and four with white flowers. Which of the following statements is true?
A) The white flowering plant is heterozygous for flower color.

B) The blue flowering plant is homozygous for flower color.

C) The blue flowering plant is heterozygous for flower color.

D) Flower color in this species is based on incomplete dominance.

2.

You have two flowers. Both are from seeds of the same parent plant. After 3 months of growth, one is 3 feet tall and has yellow flowers. The other is one foot tall and has red flowers. This is due to differences in their __________________.

Question 10 options:

genotype

genogous

phenotype

phenogous

Answer 1

Answer:

1.  C) The blue flowering plant is heterozygous for flower color.

2.  genotype

Explanation:

1. To get 1:1 ratio for plant with blue flower and white flower, the recessive plant must be homozygous. We can get desired result when a heterozygous blue flower plant (Bb) is crossed with homozygous white flower (bb). It should be noted that B is the gene for blue and b is its allele for white colour.

2. The genotype is the combination of genes contained by an organisms. Genotype determines the features of the organisms.
