Answer no 1:

sW sW sw sw

Sw SsWw SsWw Ssww Ssww

sw ssWw ssWw ssww ssww

The genotype of the parents will be Ssww and ssWw.

About 4/16 offsrings will have the genotype SsWw, 4/16 will have the genotype Ssww. 4/16 will have the gentype ssWw. 4/16 will have the genotype ssww.

About 25% will have the phenotye, smooth and wooly. About 25% will have the phenotype smooth and non wooly. About 25% will have the phenotype non- smooth and wooly. About 25 % will have the phenotype non-smooth and non- wooly.

Answer No 2)

bT bT bT bT

Bt BbTt BbTt BbTt BbTt

The genotype of the parents will be BBtt and bbTT.

As seen in the punnet square, the phenotype of all the offsprings born from such a cross will be black trotter.

Answer No 3)

wd wd wd wd

WD WwDd WwDd WwDd WwDd

The genotype of the parents will be WWDD and wwdd.

The results of the punnet square illustrate that all of the offsprings will have white flower colour and disc shaped fruit.

Answer No 4)

The phenotypes of the rabbits will be as follows:

Ggbb - Gray hair and red eyes.

ggBB- White hair and black eyes

ggbb - White hair and red eyes.

GgBb - Gray hair and black eyes

Answer No 5)

Gb Gb Gb Gb

gB GgBb GgBb GgBb GgBb

gb Ggbb Ggbb Ggbb Ggbb

8 out of 16 offspring will have Gray fur and black eyes.

8 out of 16 will have gray fur and red eyes.

0 out of 16 will have white fur and black eyes.

0 out of 16 will have white fur and red eyes.

To investigate the possible presence of introns in three newly discovered genes (X, Y, and Z), you perform an experiment in whic

REY [17]

Answer:

a). At least one intron must be present in gene X.

b). At least two intron must be present in gene Y

c). It is impossible to determine whether there are any introns in gene Z.

Explanation:

Introns may be defined as the segments in the RNA molecule or the DNA molecule that does not code for proteins and they interrupts the sequences of each of the molecules.

In the context, we get :

a). In the gene X, at least one of the intron is present. Sometimes more than one introns may also be present. Due to slicing, we get one band less in the cDNA which is made from the mRNA.

b). In dene Y, at least one intron is present. Sometimes more than one introns are present inside the gene Y. In this case we get two bands less in the gene due to slicing.

c). In gene Z, it is not possible to determine the number of introns present in them. In genes X and Y, the Haelll enzyme is present in the intron. Therefore we get less of band after splicing the mRNA to cDNA.

Which of the following is an observation?

Svetach [21]

Answer:

a. You record the air temperature every day for a week.

Explanation:

Recording air temperature every day for a week can be classified as making an observation.

Observation is a part of the scientific method. It is a basically a way of collecting data.

During observation, our senses can be used or instruments.
Depending on the nature of the study, specialized instruments helps to bridge the limitations of our senses.
A good scientist is a keen observer.
Making a record of air temperature usually by using a thermometer is a way of carrying out observation.

When you record air temperature, you are making an observation.
