Suppose your cousin has decided to begin breeding owls. She does some research and finds out that a single gene controls feather color. She really wants her owls to have brown feathers, so she buys two brown owls from a breeder and breeds them together. Imagine her surprise when they have four brown babies and one white baby (who, of course, she names Hedwig)! Using “B” to indicate the dominant allele and “b” to indicate the recessive allele. (Use this information for questions 1-?3)
Which trait is dominant?
a) brownb) whitec) Cannot be determined.
2)Assuming that non-?disjunction does NOT occur, what gametes can the brown parental owls form? (Select all that apply.)
a) b
b) bb
c) B
d) Bb
e) BB
3) What are the possible genotype(s) of the brown babies? (Select all that apply.)
a) bb
b) Bb
c) BB
The following cross involving three genes was performed: Aa Bb Cc x aa bb cc, and the phenotypes and number of progeny are shown below. Each pair of alleles exhibits simple dominance and recessiveness.
On average, how many complete turns would be in each chromosome. The human gametes have about 3 billion bp of DNA in their chromosomes.
When a pea plant of genotype Aa Bb produces gametes, what proportion would be Ab? (Assume that the two genes are independent)
Circulatory system. Describe how chemistry, tissues, and cells act as building blocks of that organ and system. You will require including information on anatomy and physiology as well as interesting facts you found while doing your research.
A number of major worldwide industries are based on anaerobic respiration in a lower form of organism.define how anaerobic respiration plays a part.
A student, who has not learned properly how to prepare solutions, added 25.7 g of sucrose to exactly 150.0 mL of dH2O and assumed that a 0.5 M solution had been prepared. The total solution volume increased to 168.0 ml after sucrose was dissolved and..
Many infected animals are induced by the parasitic microsporidians to develop huge cells, known as xenomas, which are full of spores. Given their large size, what must be true of the xenomas.
If amino acid sequences might be useful in determining how closely related dissimilar species are but may not be very useful for identifying a particular species, suggest two reasons why.
Modern theory suggests that the early pre-life atmosphere on Earth was a reducing one. Why is it believed that oxygen was not present as life formed on Earth.
Autoimmune haemolytic anaemia is caused in general by auto anti bodies of the IgG and IgM classes. Can antibodies of other classes such as IgA, IgD, IgE cause autoimmune haemolytic anaemia.
Which characteristic of cell membranes might explain why fat-soluble substances such as chloroform and ether rapidly affect cells.
Suppose the diameer of a neutral helium atom is 1.40 x 10 to the second power pm. supposed that we could line up helium atoms side by side in contact with one another. How numerous atoms would it take to make the distance from end to end 9.00cm.
