Answer:

False

Explanation:

Most scientists were not yet concerned about global warming. This was because the major issue during the period between 1940 and 1970 was global cooling with little or no attention on global warming.

However things started to change due to more pollution as a result of technological advances. Global warming started becoming a concern between 1970s and 1990s because of the increase in steady surface temperature.

In radishes, red and white are pure-breeding colors, while hybrids are purple. If a red radish is crossed with a white radish, w
zlopas [31]
The answer is 1 red radish, 2 purple radishes, and 1 white radish

Let R allele be dominant allele over r allele. The genotypes and phenotypes will be as following:
RR - red radish
rr - white radish
Rr - purple radish

Parental generation:       RR      x      rr
F1 generation:             Rr      Rr    Rr     Rr

Since the F1 generation self-pollinates, we have the situation:
F1 generation:             Rr    x    Rr
F2 generation:         RR   Rr    Rr    rr

Punnet square:
                          <u>       Rr     </u>       
                          <u>R      </u><span><u>|   r</u>
             <u>R   </u></span><u>|     RR    |   Rr</u><span>
Rr           <u>r   </u></span><u>|     Rr      </u><span><u>|  rr</u>

So, there will be 1 red radish (RR), 2 purple radishes (Rr), and 1 white radish (rr)</span>
