In humans, polydactyly (more than 5 fingers and toes on each hand and foot), is inherited in an autosomal dominant manner. what is the phenotype of an individual who is heterozygous for the mutant allele?
a. wild-type
b. 5 fingers/toes on each hand/foot
c. more than 5 fingers/toes on each hand/foot
d. 5 long and 1 short fingers/toes on each hand/foot
e. both a and b are correct.

C. More than 5 fingers/toes on each hand/foot

Explanation:

According to the given information, polydactyly is an autosomal dominant trait which means that the phenotype would be expressed in both homozygous dominant and heterozygous dominant genotype.

The given genotype is heterozygous dominant. The individuals with heterozygous dominant genotype would exhibit the polydactyly and would have more than 5 fingers and toes on each hand and foot.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
