Ryan (II-2) and Rachel (II-3) already have one son with phenylketonuria (PKU). They are about to have twins (III-2 and III-3) so they come to you for genetic counseling. You identify an RFLP that is 5 m. u. away from the PKU gene and are able to obtain a family history from Ryan whose sister has the disease. Answer the following questions assuming II-1 and III-1 inherited nonrecombinant chromosomes from their parents. To be consistent in notation, A/a refers to the PKU gene and the numbers refer to the polymorphism. How many different alleles for the polymorphism can we see here

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).

explanation:

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers
