In snapdragon the gene that affects flower color has two alleles: red (R) and white (W). In heterozygous individuals, the phenotype is pink. If two pink flowers were crossed what would be the probability of a pink offspring? A. 25%

B. 50%

C. 75%

D. 100%

The correct answer is - 50%

Explanation:

In the heterozygous condition, there is always one allele of dominant and one allele of recessive present together and during gamete formation, they assort independently. The probability of the pink flower that is RW can be found by punnet square:

      R     W

R    RR   RW

W   RW    WW

here, out of four two cases is of heterozygous or pink flower so the ration would be 2/4 or 1/2 or 50%

i think that d. wind is the answer.   i missed the question when i answered a. currents.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
