n corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).  
Corn heterozygous for kernel color and kernel  texture are fertilized with corn that is yellow and wrinkled resulting in the following offspring.
56 red smooth
40 red wrinkled
45 yellow smooth
34 yellow wrinkled
  1. What is the null hypothesis?

  2. What are the genotypes of the parents?

  3. Perform a Chi-Square analysis and determine if the observed offspring numbers conform to Mendelian expectation. Show your DF, Chi Square value, and p value

  4. Do you reject or fail to reject the null hypothesis?

  5. Do the progeny conform to Mendelian expectation?

  6. If you have to reject the null hypothesis, give two possible reasons why.

Tallness (T ) in snapdragons is dominant to dwarfism (t ), while red (R ) flower color is incompletely dominant to white (R' ). The heterozygous condition results in pink (RR' ) flower color. The genes for these traits occur on separate chromosomes. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white fowers. a) Determine the genotypes of the parents. b) Determine all the types of gametes each parent can produce. c) Complete the Punnett...

In the California poppy, an allele for yellow flowers (C) is dominant over an allele for white flowers (c). At an independently assorting locus, an allele for entire petals (F) is dominant over an allele for fringed petals (f). A plant that is homozygous for yellow and entire petals is crossed with a plant that is white and fringed. A resulting F1 plant is then crossed with a plant that is white and fringed, and the following progeny are produced:...

In Drosophila, yellow bodies (y ) and white eyes (w ) are both caused by recessive X-linked alleles. The normal alleles (y+ amd w+ ) cause tan bodies and red eyes, respectively. A y w female is mated to a y+ w+ male and the F1 progeny are allowed to mate with each other. Two hundred F2 were observed and they are: 55 y w; 45 y w+; 45 y+ w; 55 y+ w+. What is the chi-square value for...

The expression of yellow petals in sunflowers is due to the dominant allele Y. The homozygous recessive (y) has orange petals. Plant height is controlled by another gene with two alleles, T and t, with Tall (T) being dominant to short (t). Two individuals that are heterozygous for both traits are crossed, the number of offspring of each phenotype is recorded in the table below. 1. The assumption is that these two genes assort independently. To test this, complete a...
