Which of these principles/laws explains why the F1 of a
monohybrid or dihybrid cross all have the same phenotype?.
a. Equal segregation
b. Dominance
c. Uniformity
d. Independent Assortment.

1. Use a Punnett’s squares to show a monohybrid cross between
pure breeding parents of tall (T) and dwarf (t) pea plants. The
tall trait is dominant and thus is represented by the uppercase
letter “T”. The dwarf trait is recessive and is represented by to
lowercase letter “t”.
2. You have a pea plant with purple flowers but you are unsure
of it’s genotype. Since purple flowers is the dominate trait (P),
while the recessive trait is white flowers...

1. Determining Inheritance using Punnett
Squares
A Punnett is a means to determine the genetic inheritance of
offspring if the genotypes of both parents are known. Using Punnett
squares answer the questions about the following scenarios. In
order to properly answer some of the questions more than 1 Punnett
square might be needed. With every Punnett square provide a key for
your alleles.
Neurofibromatosis (NF), sometimes called von Recklinghausen
disease, is one of the most common genetic disorders. It affects...

. Give the predicted
phenotypes for the F1-generation resulting from a dihybrid
cross of the haploid gametes originating from the diploid parents,
RRtt x rrTT, in the Punnett Square below. In each
square, choose colony colour (red or white) and growth / no growth
on MIN (+ or -) from the drop-down menus. Also choose the correct
the genotypes of the haploid gametes. The RRtt parent gives rise to
the mating type “alpha” gametes and the rrTT parent forms “a”...

Performing Monohybrid Crosses
A monohybrid cross is addressing the inheritance of one gene.
Answer the following questions:
Question 1:
Drosophila melongaster, more commonly known as the
fruit fly, can have red or white eyes. You breed a red-eyed fly to
a white-eyed fly and get 50 offspring that all have red eyes. Which
trait is dominant?
Question 2:
Consider an offspring from the previous question. Its phenotype
is red eyes.
What is its genotype? (Circle one of the choices below)...
