Answer:

The correct answer will be-pachytene, prophase I,

Explanation:

Tetrad is the structure formed during the meiotic type of cell division which produces four daughter cells.

The tetrad structure is seen under the microscope during the pachytene substage of prophase I.

The tetrad structure is formed when four sister chromatids are aligned together in a cell before the crossing over event or recombination has to take place. The tetrad formation allows the crossing over to take place in pachytene.

Thus, pachytene, prophase I is the correct answer.

Suppose an animal is heterozygous AaBb, and the traits are not linked. When meiosis occurs, what is the total number of possible
GrogVix [38]

Answer:

4 possible combinations of gametes

Explanation:

The animal is considered an heterozygotic dihybrid because it involves two genes that have different alleles for both genes. The dihybrid animal undergoes meiosis to produce gametes. According to Mendel in his laws of segregation and independent assortment, the alleles of the two genes separate into gametes independently of one another to produce 4 types of gametes.

Number of possible combinations of gametes formed by an heterozygote can be determined by using 2^n, where n is the number of characters. Number of characters or genes involved in this case is 2, Hence, 2^2 = 4 gametes.

The allelic combination in the four gametes are: AB, Ab, aB, ab.
