Summary Introduction
a.
To determine:
The factors that determine the hybrid animal is viable or not.
Introduction:
Allopolyploidy is a condition in which a hybrid contains more than two sets of chromosomes which are derived from different species. Wheat is one of the examples of allopolyploidy having six sets of chromosomes.

Answer the following with a short solution if needed:
a. The gametes of a worm's genotype SsYy should produce what genotypes?
b. A genetic cross between two F1-hybrid rose plants having yellow petals will yield what percent green-petal plants in the F2 generation? Yellow petals are dominant to green.
c. Brown fur is dominant over light-colored fur. What is the phenotype of the resulting offspring if you cross a heterozygous brown fur and a light-colored fur?
Using the punnet square (mono-hybrid cross) solve the following:
In some cattle the genes for brown hair (B) and for white hair (W) are co-dominant, this condition allows cattle to show brown & white hair at the same time, and this resulting appearance is often referred to as Roan (BW). -A roan cow is crossed with a roan bull
1st Question to answer ---- How many different possible genotypes are there among the offspring?

3rd Question to answer ---- How many of the offspring could be white?
4th Question to answer ---- How many of the offspring could be roan?
An ebony strain of flies was discovered to be sensitive to carbon dioxide. Crossing a female sensitive strain with male resistant strain gave all sensitive offspring. The offspring of an F1 female crossed with a resistant male were all sensitive.
Using the following key to your illustrations using shapes, make a reciprocal cross up to the F2 generation. Put your illustrations in the space provided below. Label the phenotypes of all individuals in the reciprocal cross. Adjust spacing, if necessary. Make sure that the complete cross(es) can fit the same page.
