Answer: B Meiosis is followed by fertilization: the union of gametes to create a diploid zygote.

Explanation: Fertilization does enhance genetic variation, but not of daughter cells. It enhances genetic variation in offspring. That means two parents could have four children with a variety of traits, such as different eye color or different heights. Meiosis enhances genetic variation through the reduction of chromosomes number, crossing over, and independent and random assortment of chromosomes.

Considering the Mendelian traits tall (D) versus dwarf (d) and violet (W) versus white (w), consider the crosses below and deter

Artyom0805 [142]

Answer:

DDWw x Ddww

DdWw x DDww

DDWw x DDww

Explanation:

D for tallness

d for dwarfness

W for violet

w for white

For Parental Plants that has

tall, violet x tall, white

The representation will be

DDWW × DDww (We the apply the mendelian crossing)

This will yield offsprings with the following trait

DDDD × DwDw

DWDW x WwWw

DdWw x ddww

Ddww x ddWw

DdWw x DdWw

DDWw x ddww

From the above Offsprings

1/2 tall, white and 1/2 tall, violets offspring are

DDWw x Ddww

DdWw x DDww

DDWw x DDww
