- In dandelions, yellow flowers (L) are dominant to pink flowers (1), and tall plants (T') are dominant to short plants (t). Note: assume that the genes are located on separate chromosomes (i.e., not linked) when you predict the results of this cross. a. Draw a Punnett square to illustrate a cross between a dandelion homozygous for tall and yellow flowers and a short dandelion with pink flowers. What are the resulting genotype and phenotype of the F;? b. Draw a Punnett square to illustrate a cross between a dandelion heterozygous for flower colour and height and a dandelion homozygous recessive for both characteristics.

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.
