Answer:
Parents: yellow, entire petals (CC FF) × white, fringed petals (cc ff) F1 (Cc Ff)
For the cross of a heterozygous F1 individual (Cc Ff) with a homozygous recessive
individual (cc ff) we would expect a phenotypic ratio of 1:1:1:1 for the different phenotypic classes.
Phenotype Observed (O) Expected (E) (O - E)2/ E or ( 2)
Yellow, entire 54 43.75 2.40
Yellow, fringed 58 43.75 4.64
White, entire 53 43.75 1.96
White, fringed 10 43.75 26.0
Total 175 175 35
Degrees of freedom = 4 - 1 = 3. The chi-square value is greater than 12.838 for a probability value less than .005, or 0.5% that random chance produced the observed ratio of California poppies.
B .t is unlikely that random variations produced the observed ratio.

The answer is <span>B. Stratosphere </span>
<span>Investigations of the legacy of natural selection in the human genome have proved particularly informative, pinpointing functionally important regions that have participated in our genetic adaptation to the environment. Furthermore, genetic dissection of the intensity and type of selection acting on human genes can be used to predict involvement in different forms and severities of human diseases.</span>
