Assume that a cross is made between a heterozygous tall pea plant and a homozygous short pea plant. Fifty offspring are produced with 30 tall and 20 short plants. A genetics student hypothesizes that the data fit a ratio of 1:1 and wants to test the hypothesis by performing a chi-square analysis. Should the hypothesis be accepted or rejected? Why? A) should be accepted, p value is greater than 0.05 B) should be accepted, p value is smaller than 0.05...

Purple flowers (P) are completely dominant over white flowers (p) in pea plants. A plant that is heterozygous for purple flowers (male) is crossed with another plant that has white flowers (female). Use a Punnett square to determine the expected genotypic and phenotypic ratios for the offspring. What is the purple pea plant's genotype? What is the white pea plant's genotype? What are the purple pea plant's gametes? What are the white pea plant's gametes? What is the expected genotypic...

In a typical Mendelian cross (i.e. independent assortment of the genes is expected) between two heterozygous plants (Rr x Rr) We obtain the following results. RR=360, Rr=480 and rr= 160 Draw your own table, calculate your allele frequencies, genotype frequencies (observed and expected) and use your observed and expected counts to find X2. What will be the degree of freedom? Do we accept or reject the null hypothesis of HWE?

You performed a dihybrid test cross between flies that were heterozygous for both traits and flies that were homozygous recessive for both traits. The results showed some variation from the predicted 1:1:1:1 phenotypic ratio, but the P value was determined to be .25 (insignificant)or good fit. What can you conclude about these two genes that are responsible for the observed traits and why?   (Hint: law of independent assortment is being tested)

Draw a Punnett square representing the cross between a heterozygous individual and a homozygous recessive individual for gene A. Assume that gene A is inherited in a normal Mendelian fashion and assorts independently. What are the chances that these two individuals would have offspring that are… AA? Aa? aa? What alleles are in each of the gametes (sperm & eggs) for the heterozygous individual? Now let’s practice using the “rule of and.” What are the chance of the offspring from...
