In rose bushes, red flowers are dominant to white flowers. A purebred (homozygous) red rose is crossed with a white rose.  Two roses from this parental cross (two of the F1 offspring) are then crossed. What will be the most common genotype of the next generation (F2) ? Heterozygous White roses Homozygous recessive Red roses Homozygous dominant

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.
