Dog breeding involves the application of genetics. Genetics, on the other hand, involves some mathematics, especially when dealing with allelic frequencies of a population. It is important to know the allelic frequency of recessive and dominant alleles in the dog population so as to determine how to breed the population to achieve a desired population.
Answer:
He would need to cross one homzygous red (RR) and homzygous white (rr)
Explanation:
Flower color in snapdragons is controlled by a gene whose alleles exhibits incomplete dominance. The allele for red coloration (R) is incompletely dominant over the allele for white coloration (r). The intermediate phenotype that is produced in an heterozygous state (Rr) is PINK.
According to this question, a botanist wanted to produce a generation of snapdragons that all had pink flowers (Rr). This means that in order to do this, the botanist would need to cross a red snapdragon plant (RR) and a white snapdragon plant (rr) to produce an 100% Pink (Rr) snapdragon in the F1 generation.
C all living things are made of cells
Answer:
ion.
Explanation:
When an atom gains a positive or negative charge, that atom is called an ion.
D! Because a gas takes its form and volume of its container
