The first step of the dihybrid cross is to mate the P generation: A PUREBRED (homozygous) plant producing PURPLE and SMOOTH kernels (PPSS) is mated with the PUREBRED (homozygous) plant producing YELLOW and WRINKLED kernels (ppss), as pictured below. 6. Illustrate the dihybrid cross from the parental generation through the F1 and F2 generations. Use a Punnett Square to predict the ratio of genotypes and phenotypes in the F1 generation of this cross. P generation: Purebred purple, smooth corn Purebred yellow, wrinkled corn Parent Genotype: PPSS ppss Possible Gamete(s): or or or or or or Punnett Square F1 offspring: PXI

Codominance in blood types. If a male with type A blood (with genotype IAi) mates with a female having type B blood (with genotype IBi), what are the phenotypic ratios for the blood types of the offspring? ___ A : ___ B : ___ AB : ____ O Suppose that one parent has type AB blood, and the blood type of the other parent is not known. Describe how a child can (or cannot) have the following blood types: Type A Type B Type AB Type O
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. Given a pure-breeding cross between a round, green pea plant and a wrinkled yellow plant, complete the rest of the Punnett Squares below, and answer the following questions. R R A A RA Ra Ra ra
GENETICS In a sexually reproducing diploid organism in which 2n=6, a normal meiocyte in reduction should exhibit a total of 3 bivalents at the metaphase plate. Consider the following organism in the previous statement. if there is no crossing over, the number of possible haploids (gamete) genotypes generated by "chromosome shuffling" during meiosis is _____?
Need help. Knowing that the Curly leaf (Cy) is a dominant gene on chromosome 6, as it is useful in tracking other genes using trisomics for chromosome 6. Assume a Cy Cy cy plant used as a pollen parent where disomic pollen does not function crossed to a Cy cy cy female where disomic eggs do function. A) What ratio would be predicted in the progeny of this cross? B) What if the reciprocal cross was made?
Equalizing the Expression of X Chromosome Genes in Males and Females Individuals with an XXY genotype are sterile males. If one X is inactivated early in embryogenesis, the genotype of the individual effectively becomes XY. Why will this individual not develop as a normal male?
Analysis of X-Linked Dominant and Recessive Traits Suppose a couple, both phenotypically normal, have two children: one unaffected daughter and one son affected with a genetic disorder. The phenotype ratio is 1:1, making it difficult to determine whether the trait is autosomal or X-linked. With your knowledge of genetics, what are the genotypes of the parents and children in the autosomal case? In the X-linked case?
