Pea flowers may be purple (p) or white (p). pea seeds may be round (r) or wrinkled (r). what proportion of the offspring from a cross between purple-flowered, round-seeded individuals (heterozygous for both traits) will have both white flowers and round seeds? b. 1/2 c. 3/16 a. 1/16 e. 9/16 d. 3/4

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.  

the eggs of the insects should be the first thing collected at the scene.

false

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive
