A) it is possible if they both have the recessive O type
DNA carries the "codes" that communicate what traits will be formed. The nucleotides in DNA are read and transcribed into mRNA which travels ot of the cells nucleus and then goes to a ribosome. In the ribosome, tRNA matches to mRNA with its anticodon. Each of the tRNA molecules are carrying an amino acid which are all connected by the ribosome to create an amino acid chain, which is a protein, which are traits in an organisms.
Stem cell research has and can lead to medical cures.
Answer:
Antigens on red blood cells are hereditary traits that allow blood to be typed in different ways. One system is based on a gene with two alleles, M and N. If the frequency of the M allele in a population is 0.4, then according to the Hardy-Weinberg rule, the expected frequency of the heterozygous MN genotype is 0.48.
