Question: Flower color in snapdragons is due to a gene with incomplete dominance: CRCR plants have red flowers, CRCW have pink flowers, and CWCW plants have white flowers. Which cross is expected to yield progeny with flower colors in a ratio of 1 red:1 pink?
A. CRCR × CRCW
B. CRCR × CWCW
C. CRCW × CRCW
D. CRCW × CWCW
E. CWCW × CWCW
Answer:
A. CRCR × CRCW
Explanation:
According to the given information, the flower color gene in snapdragon exhibits incomplete dominance. When a snapdragon plant with red flowers is crossed with a snapdragon plant with pink flowers, it obtains progeny in following phenotype ratio= 1 Red (CRCR): 1 Pink (CRCW).
Here, the genotype of the parent with the red flowers is CRCR and that of the parent plant with pink flowers is CRCW. The parent plant with pink flowers produces two types of gametes carrying CR or CW alleles. Random fusion of gametes of the two parent plants obtains the progeny in 1 red: 1 pink ratio.
The answer is; Physical weathering by water would carve out the face of the cliff.
The bottom of the cliff would register the greatest weathering because of the force of the water hitting the rocks in the fall. As a cave is curved from the base of the cliff, the overhanging part of the cliff eventually collapses hence retracting the cliff a small distance upstream of the river. The diagram below demonstrates this;
