The answer is C. This conclusion is drawn from the understanding that roan coat coloration arises in heterozygous offspring produced by homozygous red and white parents, thereby nullifying option A, which involves two red parents. In B, the cross between CRCR and CRCW generates two roan and two red offspring but no white - eliminating that as a viable option. Option D, involving red and white homozygous parents, solely produces roan offspring. In option E, a cross of CWCW with CRCW yields two roan and two white but no red. Thus, option C remains valid as the cross of CRCW with CRCW results in 1 red, 2 roan, and 1 white offspring, matching the desired ratio.

When a farmer ceases to cultivate a large piece of land and leaves it, the emergence of wild grasses and weeds is termed as secondary succession since there is existing soil. Secondary succession arises in ecosystems where the soil has been altered or affected by human activities, such as farming. This situation does not qualify as primary succession because that only happens in regions devoid of life, where soil cannot support organisms. This specific type is known as old-field succession, where wild grasses and weeds represent new plant species populating barren soil after farming has ceased.
