Answer:
I-3, II-2, III-2 are all definitely carriers
It is possible find the genotype of individual II-1 because the he inherited his father's y which does not carry the trait (because only x chromosomes have the trait) and his mother's x chromosome, but the mother is not a carrier.

Answer:
By performing a test cross i.e. a cross with a recessive trait
Explanation:
According to the question, hairlessness is a recessive trait, meaning that it will only be expressed in a homozygous condition i.e. when there are two recessive alleles in the genotype. Presence of hair is dominant, meaning that it will mask the phenotypic expression of hairlessness allele in a heterozygous state. Hence, a dominant phenotype can either be homozygous (same dominant allele) or heterozygous (combination of dominant and recessive alleles).
In order to determine which of these genotypes the dominant phenotype possess, we perform a test cross. A test cross is a cross performed to determine the genotype of the dominant organism by crossing it with a homozygous recessive genotype.
Ideally, the offsprings resulting from the cross will all be phenotypically dominant if the organism in question is homozygous dominant but if the organism is heterozygous dominant, the offsprings will occur in an equal ratio of dominant to recessive phenotypes.
So in this case, all of offsprings of this cross between the rat terriers will possess hair if the dominant rat terrier dog is homozygous, but if the dominant rat terrier dog is heterozygous, an hairless offspring will be produced.
Answer:a product consisting of a natural raw material; an unmanufactured product. Many primary products are exported for processing to the developed nations.
Explanation:
<span>Something that occurs outside the spheres of the earth
Consider that human beings or living organisms live in the biosphere. Biosphere is the collective group of living organisms and their interaction to one another and –ecosystem- to their environment. Human beings like animals or plants are part of the biosphere, one of the spheres in the earth. We have the atmosphere (air), lithosphere (land), hydrosphere (water) and the biosphere (life/ living organisms). Each is with a specific and distinctive characteristics to play in the earth’s existence at the current era.<span>
