In guinea pigs, the allele for black hair (B) is dominant to the allele for brown hair (b). The allele for short
hair (S) is dominant to the allele for long hair (s). The genes for hair color and hair length are located on
different chromosomes. Guinea pigs with black, short hair (BbSs) are crossed with guinea pigs with brown,
long hair (bbss). Some offspring have black, short hair or brown, long hair like the parents. Additionally,
some offspring have black, long hair or brown, short hair. Which of the following explains the different
phenotypes in the offspring?
a. The expression of the alleles for hair color is influenced by the alleles for hair length.
b. The alleles for hair color and hair length assort independently during gamete formation.
c. The alleles for hair color and hair length mutate during the first cell divisions of the
offspring.
d. The interaction between the alleles for hair color and hair length is incomplete dominance

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements. the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center. because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane. the diverse proteins found in and attached to membranes perform many important functions. the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together. membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
