This heat trapping is known as the greenhouse effect. ... Putting so much new CO2 into the air has made Earth warmer.
20% would be guanine.
All 4 bases must equal 100.
30 thymine+30 adenine=60
100-60=40 of guanine and cytosine
40÷2=20 is just guanine
The given case says, the pure breed purple flower is crossed with pure breed white flower. The pure breed traits are always homozygous in nature.
On crossing white and purple flower, all the progeny have a phenotype of purple flower. In cross reproduction, the progeny inherit one allele from each parent. So, in the progeny, there would be one allele for purple and one for white, but the phenotype is purple, so, it suggest that purple trait masks the effect of white trait. Hence, the purple phenotype is dominant over white phenotype.
The given cross represent the cross between purple (PP) and white (pp) pure breeds.
