mentioned in the footnote on p. 263‚ we have simplified the explanation in referring to the single pea plant as a parent. Technically‚ the gametophytes in the flower are the two “parents.”) Concept Check 14.2 1. For any gene with a dominant allele A and recessive allele a‚ what proportions of the offspring from an AA Aa cross are expected to be homozygous dominant‚ homozygous recessive‚ and heterozygous? 1. 1⁄2 homozygous dominant (AA)‚ 0 homozygous recessive (aa)‚ and 1⁄2 heterozygous

1. Explain what must happen in order for Greg and Susan to have a child with O type blood and nail-patella syndrome. Greg needs to pass down his chromosome 9 which carry the alleles‚ n and i. Susan also has the n and I alleles on chromosome 9. If both these alleles from both parents are passed down‚ it will create the allele Nnii which produced the blood type O and nail patella syndrome. 2. Determine all possible parental and recombinant gametes produced by Greg and Susan. Greg’s parental gametes

carried the B allele‚ while those produced by the albino parent carried the b allele. The F1 offspring of such a cross would be Bb‚ and since black is dominant over albino‚ all the F1 animals would have had black fur. +1 point Second Cross: Since some of the F1 offspring are albino‚ that means that the black parent must have been heterozygous for fur color. So‚ the parents of the second cross were Bb x bb. The black parent would have produced gametes carrying either the B or the b allele‚ while the

Chapter 6 Explain what free energy is and how it can be used to predict the energetic outcome of chemical reactions.Free energy is defined as the energy available to do work in any system. The free energy is denoted by the symbol G. G = H – TS* H: the energy contained in a molecule’s chemical bonds‚ called enthalpy.* TS: the energy term related to the degree of disorder in the system. T is the absolute temperature (K)‚ and S is the entropy.We can use the change in free energy to predict whether
