1. Dihybrid crosses involving plants with either white or yellow flower and either tall or short morphs were done. The yellow allele is dominant over the white allele, and the tall allele is dominant over the short allele. The following are the observed numbers of each combination. Do these data fit the expected distribution?

TYPE	OBS FREQ	EXP PROP
YELLOW, TALL	90	0.5625
YELLOW, SHORT	52	0.1875
WHITE, TALL	46	0.1875
WHITE, SHORT	24	0.0625

a. what kind of statistical test needs to be performed?

b. Will you need to test for equal variance? If so, what are your results and how does that influence the next steps in your analysis?

c.What are your null and alternative hypotheses?

H0:

HA:

d. Discuss the results of your analysis. Will you accept or reject your null hypothesis? Why? What can you specifically say about the data?

You perform a dihybrid cross of plants. The first trait is flower color. “A” is the dominant allele and causes red petals and “a” is the recessive allele and causes white petals. Stem length is the second trait. “L” is the dominant allele and causes a long stem and “l” is the recessive allele and causes short stems. You cross a Red Long plant that is heterozygous for both traits with a Red Short plant that is heterozygous for color....

You set up a dihybrid cross between true-breeding tall pea plant with white flowers and a true-breeding short pea plant with purple flowers. Your F1 generation looks uniformly tall with purple flowers. The results of the F2 generation counts are shown in the table below: Phenotype Number of progeny Tall/purple flowers 850 Short/purple flowers 350 Short/white flowers 87 Tall/white flowers 313 Your calculated Chi square test statistic for this analysis is: a. 8.31 b. 3.37 c. 4.19 d. 16.3 e....

In garden peas, tall plants are dominant to short plants and smooth seeds are dominant over wrinkled seeds. If two heterozygous tall plants with smooth seeds (TtRr) are crossed, what are the potential genotypes and phenotypes that can be expected in the offspring? What is the genotype of the parents? What are the gametes for each parent? What is the phenotypic ratio? What proportion of the Tall plants with smooth seeds is heterozygous for both traits?

According to a theory in genetics, if tall and colorful plants are crossed with short and colorless plants, four types of plants will result: tall and colorful, tall and colorless, short and colorful, and short and colorless, with corresponding probabilities: 0.37, 0.42, 0.11 and 0.10. ten plants are selected. find the probability that 5 will be tall and colorful, 2 will be tall and colorless, 2 will be short and colorful, and 1 will be short and colorless.
