150
Explanation:
According to the given information, the pink-flowered plant (Rr) is crossed with a red-flowered plant (RR). The pink-flowered plant would make two types of gametes: 1/2 with "R" and 1/2 with "r".
The red-flowered plant would make all gametes with "R" allele. The random fusion of these gametes gives pink and red-flowered progeny in 1:1 ratio.
Since 50% of plants of the progeny are red-flowered, out of 300 offspring, the total red-flowered plants would be= 50 % of 300 = 150.
Answer:
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically.
