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.

Answer:
B. Genotypes
Explanation:
The genotype of an organism refers to the genetic makeup of that organism. It is the combination of all the genes contained on the chromosomes of that organism. Gregor Mendel, who is considered to be the Father of Genetics, discovered that certain factors are responsible for the physical characteristics of organisms and that they can be transferred from one generation to another. These factors are called GENES. Genes are located on X-shaped structures called chromosomes.
Hence, the isolation of chromosomes taken from tortoise blood samples refers to recording their GENOTYPE (genetic constituent).
Answer:
No, because it is a sign of damage. Although it is better than a burn, it means that DNA has damaged itself. It is the repair mechanism that stimulates more melanin production.
