- Question: Suppose the progeny were crossed. Fill in the Punnett Squares below and answer the following questions. Seed Color Seed Shape R r A a In a pea plant experiment, the allele (R) producing yellow seed color is dominant, and the allele (r) producing green seed color is recessive. A homozygous recessive genotype would produce green seeds. Similarly, the allele (A) producing round seed shape is dominant to the allele (a) that produces wrinkled seed shape. A homozygous recessive genotype would produce wrinkled seeds. Both traits sort independently of each other.

- Question: This is a normal 3 point test cross, except that instead of regular phenotypes, you are looking at DNA markers on a gel. One parent, according to the gel, is heterozygous at each marker. The other parent is homozygous for each marker. (Again, this means it is a test cross: AaEeHh x AAEEHH --but don't be confused by that, because these are not "dominant" and "recessive" per se; the phenotype is just a band on a gel). For each offspring, figure out its genotype (homozygous or heterozygous for each gene. Then, figure that one parent made only AEH gametes, so you can cross that out if it helps.) Then treat it pretty much the same as a 3 point test cross.arrow_forwardMODIFIED TRUE OR FALSE. In the following items, read each statement carefully. I. The Mendelian pattern of inheritance is a general term that refers to any pattern of inheritance in which traits do not segregate in accordance with Mendel’s lawsII.

The X chromosome carries information for many traits that aren't related to the sex of the individual. Alleles carried only by the X chromosome are said to be X-linked (or some-times, sex-linked). Some of the alleles on the tiny Y chromosome appear to have no counterparts on X. These Y-linked alleles code for traits that are found only in males. Among the X-linked traits are a number of recessive genetic disorders. One of these is hemophilia, the inability to produce proteins necessary for blood clotting. Hemophiliacs can bleed to death from relatively minor cuts or bruises. Historical records dating back thousands of years mention the inheritance pattern of hemophilia. Among the ancient Hebrews, sons born to women with a family history of hemophilia were excused from circumcision. Hemophilia was common during the 1800s in the royal families of Europe, whose members often intermarried.…arrow_forward
