or many students, calculating the chi square value is the most challenging part of conducting a chi square test so it is important to practice. Consider the following information: An F1 tall, round seed pea plant is crossed with a dwarf, wrinkled seed pea plant. The following offspring are observed: Tall, round: 510 Tall, wrinkled: 495 Dwarf, round: 490 Dwarf, wrinkled: 505   a. What is the expected phenotype ratio? #:# or #:#:#:#, depending on what you think the answer is. b. What is the calculated chi-square value? Format your answer with 1 significant digit (i.e. 0.#).  c. What is the critical chi-square value from the table provided in the book at the P=0.05 level of significance? Enter the number exactly as shown in this table

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
