The temperature in an autoclave must reach 121° C in order for sterilization to occur.

<h3>Sterilization using autoclaves</h3>

Autoclaves are used to wet-sterilize materials in the laboratory.

In order for the sterilization to be effective, the temperature of the autoclave must reach 121° C.

Also, substances to be sterilized must spend, at least, 30 minutes in the autoclave.

soldi70 [24.7K]

Answer:

The correct answer is c. 3/16.

Explanation:

In the given question two traits being studied, the traits are flower color and seed shape.

This is a typical Mendel’s dihybrid cross. According to the question purple colour (P) and round seed (R) are dominant traits.

When heterozygous purple-flowered (Pp), round-seeded (Rr) individuals are crossed, four different types of plants are produced phenotypically in the ratio 9:3:3:1.Out of 16 offspring, 9 are purple flowered, round seeded pea plants, 3 pea plants are white-flower with round seed, 3 are purple- flower with wrinkled seed and 1 pea plant is white-flowered with wrinkled seed pea plant is produced.

lukranit [14]

Answer:

1/4

Explanation:

Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.

YyRr X YyRr:

Let us break the dihybrid cross into individual monohybrid crosses.

Yy X Yy :

    Y     y

Y  YY  Yy

y   Yy   yy

2/4 or 1/2 of the offspring are heterozygous for the trait.

Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.

Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
