I need help with these practice bio questions! (Gr. 11 Bio) 1) Ms. K has blonde hair, a recessive trait. Her husband has brown hair, a dominant trait. Her second daughter has blonde hair. How is this possible? Use a punnett square to show how the genotypes of Ms. K and her husband could produce a blonde hair child. Include genotypic and phenotypic frequencies.        2) Explain with both proper terminology and a punnett square, why it is not possible for two white pea flowers (white is a recessive trait) could produce a purple flower.       3) Explain with both proper terminology and a punnett square why recessive traits can remain “hidden” in generations. Be sure to explain the difference between phenotype and genotype.

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.
