Long hair in guinea pigs is a recessive trait. A female guinea pig with long hair mates and have all heterozygous offspring, what are the genotypes of the male?

The male's genotype is homzygous short (LL)

Explanation:

This question involves a single gene coding for hair length in guinea pigs. The allele for short hair (L) is dominant over the allele for long hair (l). This means that a heterozygote will have short hair (Ll) while a guinea pig with long hair will have genotype ll.

According to this question, a female guinea pig with long hair (ll) mates and have all heterozygous offspring (Ll). This means that the male guinea pig provided only the allele for short hair (L) that made the offsprings all short. In other words, the male's genotype is LL i.e. homzygous short.

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.
