In corn, a certain gene cause the kernels to turn red when exposed to sunlight. The trait is known as sun-red (c*). An allele of this gene has been found that causes a very pale red trait called dilute sun-red (cd). Still a 3rd allele causes a less intense red to develop- the trait is known as weak sun-red (c) The following results were obtained from these crosses: Cross sun-red x dilute sun-red x weak weak x dilute Show the dominance relationships among these alleles. all sun-red all sun-red all weak F1 984 sun-red: 314 dilute 66 sun-red: 16 weak 1,300 weak: 429 dilute F2

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.
