Textbook Question
Chapter 28.4, Problem 1CS
Core Skill: Modeling The goal of this modeling challenge is to make a simplified model of the one shown in Figure 28.29, to determine if the latter represents a life cycle that is diploid dominant, haploid dominant, or an alternation of generations.
Modeling Challenge: Chapter 16 describes the three basic types of eukaryotic sexual life cycles (refer back to Figure 16.14). These cycles are modeled by circular diagrams that show life phases connected by the processes of fertilization, meiosis, and mitotic cell divisions. Animals display a diploid-dominant life cycle;
Figure 28.29 Diagram of the life cycle of Plasmodium falciparum, a species that causes malaria in humans. This life cycle requires two alternate hosts, humans and Anopheles mosquitoes. Parasite life stages known as sporozoites are transmitted by a mosquito bite, then infect the liver. The parasite life stages known as merozoites are produced in the liver, and infect red blood cells.

Challenge Question! If a pregnant woman had a karyotype prepared for her baby before birth, would it be more useful in predicting the risk of Down Syndrome or Tay Sachs disease? Explain your answer completely and in detail.
Task #3 Impact of allelic difference: The receptor protein encoded by the recessive m allele sequence cannot bind its hormone partner, and as a result the fur pigment eumelanin is not effectively produced. Briefly explain how one amino acid change might impact the function of the receptor protein.
Task # 4 Genotypes and Phenotypes: The Mc1r gene is located on chromosome #16 in mice. Mice are diploid so every somatic cell has two copies of the Mc1r gene. Since there are two Mc1r alleles there are three possible genotypes: MM, Mm and mm.
M=dark pigment m=less pigmentParental generation: an inland mouse (MM) mates with a beach mouse (mm)
A. What is the genotype of the F1 offspring? ________B. If this trait exhibits simple (Mendelian) dominance, circle the phenotype expected for
the F1 fur color: dark pigment / medium pigment / less pigment
Observed phenotype: F1 actually have medium pigment. Initially this looks like blending, but it is not. M and m are discrete units. This observation…
