The height of a weed is the result of polygenic : inheritance involving three genes,each which contribute 5 cm to the plant . The base llowest height)is 10cm and the tallest is 40 cm. Question 1(1 point) How tall would a plant be if it has the genotype AaBBCc? 10 cm 15 cm 20 cm 25 cm 30 cm 35 cm 40 cm

Here's how to solve this problem:<br /><br />1. **Determine the number of contributing alleles:** The genotype AaBBCc has two capital 'A' alleles (one 'A' and one 'a' - only the capital letter contributes to height), two capital 'B' alleles, and one capital 'C' allele. This gives us a total of 5 contributing alleles.<br /><br />2. **Calculate the height contributed by the alleles:** Each contributing allele adds 5 cm to the base height. Therefore, 5 alleles contribute 5 cm/allele * 5 alleles = 25 cm.<br /><br />3. **Add the base height:** The base height is 10 cm. Adding the contribution from the alleles, we get 10 cm + 25 cm = 35 cm.<br /><br />**Therefore, the correct answer is 35 cm.**<br />
