Acell with three pairs of chromosomes has the genotype aabbcc, such that each pair of alleles is on a different pair of chromosomes. if this cell were to undergo meiotic division, how many genetically different types of gametes could be produced?

8 genetically different types of gametes.

Explanation:

This is typical heterozygotic trihybrid individual i.e. an individual with three pairs of contrasting characters possessing different alleles on each gene. This is similar to Mendel's observation of F1 hybrid.

According to Mendel's law of independent assortment, the alleles get sorted into gametes independently of one another. Hence, this hybrid (AaBbCc) with three unlinked genes produces 8 genetically different gametes after undergoing meosis viz:

ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc.

The number of gametes formed by this trihybrid heterozygote (AaBbCc) is determined by the formula 2^n, where n represents the number of characters.

Since this is a trihybrid cell involving three unlinked genes, 2^3 = 8

i.e. 8 gametes will be produced as stated earlier.

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.
