magine we are selecting porcupines to make them pricklier. The narrow-sense heritability of prickliness is 0.7. Average prickliness in the population before selection is 100 Pu (prickly-units). We have identified two very prickly porcupines to be the founding individuals for the next generation. The prickliness of the mother is 112 Pu and the prickliness of the father is 108 Pu. What will the prickliness of their offspring be?  _____ Pu

Are these all correct? Last two questions are 8. What is the critical value? Round to two decimal places. 9. What is your conclusion from the chi-square test? option 1: Fail to reject H option 2: Reject Ho

Normal text BIUA Arial 14 E I 1 | I 11 3 Now, let's examine a couple more examples of phenotypic plasticity. 3. Example 2: The American Peppered Moth caterpillars (Biston betularia cognataria) are able to change their color based on the color of the twigs in which they live. What advantage might this provide to these caterpillars? Biston betularia caterpillars on birch (left) and willow (right). Support Schoology Blog I PRIVACY POLICY Terms of Use !!!

In an ideal population of plants with red (due to dominant “R” allele) or white flowers (due to recessive “r” allele), the frequency of white flowers is 9%. Draw a Punnett square and identify the location of the white flowered plants within the square using the color red. Identify where the “R” allele is designated on the Punnett square using the color green. What is the frequency of the “R” allele? a) 9% b) 30% c) 91%                             d) 70%

Think about a population of 50 individuals. In this population there are 6 individuals that have a homozygous recessive genotype and 9 individuals have a heterozygous genotype. The gene exhibits complete dominance. What proportion of individuals exhibit a dominant phenotype? Check both your the way that you think of this and how you calculate this one. Write it out.

Flower color variation in Phlox drummondii living either in sympatry or allopatry with Phlox cuspidata has previously been studied. Phlox drummondii exist in four colors: light blue, dark blue, light red, and dark red. Each flower color is controlled by a specific combination of alleles. In allopatry, butterflies randomly pollinate Phlox drummondii flowers of all color types. In contrast, non-random pollination occurs between differently colored flowers when both Phlox species are living in sympatry. The graph depicts the relative fitness of the alleles that drive flower color in Phlox drummondii under conditions of sympatry or allopatry with Phlox cuspidata. Label each half of the graph with the term sympatry or allopatry based on the observed trend in the relative fitness of the alleles that control all four flower colors in Phlox drummondii.

What is the chi-square value of the pumpkin population? round up and use four decimal points After doing some crosses and genotyping some individuals, you determined that the number of individuals homozygous dominant for the largest pumpkin allele is 98, 80 are heterozygous for medium size, and 20 are homozygous recessive for small size.

In carnations, the red pigment (RR) is incompletely dominant to white (rr). The heterozygote (Rr) is pink. In a randomly mating field of carnations, 42 plants were red, 178 plants were pink, and 180 plants were white (total =400). What is the best estimate of the allele ferequency, for the red allele in this population?

Can you please make a conclusion for this? Thank you so much!   Suppose you counted 79 R_ and 33 rr. The total number of individuals you counted, N, is 112. You expect 3/4 to be R_ (84) and 1/4 to be rr (28). Are your results close enough to these ratios for you to accept the null hypothesis—that there is no real difference?   Individual'sPhenotype Observed number Observed Ratio Expected Ratio Expected Number (Observed no. – Expected no.)^2 / Expected number R_ 79 2.8 3 84 (79-84) ^2 = 25/84 = 0.297 rr 33 1.18 1 28 (33-28) ^2 = 25/28 = 0.893  TOTAL: 112       Chi Square Value =  1.19 Degrees of freedom = 1
