Answer:
B. 0.50
Explanation:
The estimated frequency of allele A in the gene pool is 0.50. Allele A is a variant form of gene which has different forms located at same position. Allele frequency determines common presence of genetic locus of an allele in the population. It is calculated by dividing the number of common allele that appears in the population by total number of copies of genes.
Answer:
50%
Explanation:
CF is a recessive trait. That means that an individual must have two copies of the recessive allele in their genotype in order to express the trait. That means that the parent with CF has genotype cc, while the parent who is heterozygous, and does not express the trait, has genotype Cc. Using a Punnett square to demonstrate the cross of these two parents will produce a probability of 50% heterozygous and 50% positive for CF.
Try looking up diagrams of Leaf structures, that would be my best solution sorry
Answer: Oxygen has a negative ion.
Explanation: In a water molecule, the oxygen atom and hydrogen atoms share electrons in covalent bonds, but the sharing is not equal. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
