In rabbits, an allelic series helps to determine coat color at the color C locus: C (full color), cch(chinchilla; gray color), ch (Himalayan; white with black extremities), and c (albino; all white). The C allele is dominant to all others, cch is dominant to ch and c, ch is dominant to c, and c is recessive to all the other alleles. What types of progeny would you predict from a cross of Cch x cch
Answers
Answer:
1 Full color : 1 Himalayan
Explanation:
This question is depicting the multiple allele phenomenon in rabbits where four different alleles are responsible for coat color. The alleles are:
- C codes for full color
- cch codes for chinchilla; gray color
- ch codes for Himalayan; white with black extremities, and
- c codes for albino; all white
However, according to the question, the order of dominance of these alleles is: C > cch > ch > c. Hence, in a cross between Cch x chc, the following gametes will be produced by each parent:
Cch - C and ch
chc - ch and c
Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced;
Cc = full color
Cch = full color
chc = Himalayan (white with black extremities)
chch = Himalayan (white with black extremities)
Hence, full color and Himalayan are the types of progeny that will be predicted from the cross.

The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. What is the likelihood that their first child will be a taster
Answers
Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.

Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future.
a. True
b. False
Answers
Answer:
True
Explanation:
There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing random distribution of the two traits. This random distribution cannot be captured through punnet square.
The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.

B The climate would get warmer and wetter as you go up the mountain.
C The climate would stay the same because you are in the same climate zone.
D The climate would be similar to a tropical climate zone as you go up the mountain.
Answers
C
Explanation:
It’s easy
The climate would get colder and drier as we go up the mountain. So, the correct option is A.
What is the effect of altitude on the atmosphere?When altitude increases, the amount of gas molecules in the air decreases, so the air becomes less dense than air closer to sea level, which is what meteorologists and climbers mean by "thin air". Thinner air exerts less pressure than air at lower altitudes.
Most of the gas molecules in the atmosphere are pulled closer to the Earth's surface by gravity, so gas particles are denser near the surface, so with more gas particles in a given volume, there are more collisions of particles and therefore more pressure.
Thus, the climate would get colder and drier as we go up the mountain. So, the correct option is A.
