Answer:
The correct answer is option D.
Explanation:
Linkage mapping is the mapping process in which the genes present on the chromosomes are mapped on the base of their linkage. The linkage mapping helps in calculating how frequent recombination occurs using testcross.
Linkage mapping does not utilize the information that is on DNA sequences, however, it helps in assuming the distance of two linked genes is proportional of the recombination frequency. By the recombination, frequency mutations can be found and study.
Thus, the correct answer is option D.

Answer:
46 and 88° or 67 and 67°
Explanation:
An isosceles triangle has two sides of equal length and one other of a different length;
A triangle with such features also has 2 equal angles and one other;
If we consider that 46° is the angle that is not one of the two equal ones, then we can calculate the other two;
All angles in a triangle sum to 180, so:
180 - 46 = 134
The two remaining angles constitute 134° collectively;
If they are equal, each angle can be found like so:
¹³⁴/₂ = 67
Each of the two equal angles will be 67°;
Alternatively, if 46° is one of the two equal angles, then these two angles will be:
46 × 2 = 92
Then, the remaining angle can be found like so:
180 - 92 = 88
So the angles within the triangle are either:
46, 46 and 88°
or
46, 67 and 67°
Answer:
Megaspore—2n.
Explanation:
Angiosperms are the fruit bearing plants and reproduce by the process of sexual reproduction. The chromosome number are specific at each stage of the cell cycle of the angiosperms.
Microspores , egg are haploid. Zygote is diploid in nature. Megaspores get germinate into the female gametophytes and these are haploid in nature. Megaspores are also haploid in angiosperms.
Thus, the correct answer is option (b).
Answer:
D.Georgia to Alabama
Explanation:
There are records of manatee sighting during the summer months in areas such as Alabama, Georgia and South Carolina. They migrate north in the summer months.
The manatees do not withstand temperatures below 21 degrees Celsius.
Most manatees migrate seasonally over long distances between a northern warm season range.
In winter the manatees are concentrated in Florida.
