Mendelian punnett squares: 1. in flowers, purple is dominant to white for flower color. 2. a flower that is heterozygous for flower color is crossed with a flower that is white. 3. what percentage of children that will be white

Explanation:

Purple is dominant to white so

P > W

A flower that is heterozygous for flower colour can be represented by genotype PW and a white flower will be represented by genotype WW.

When they are crossed following offspring with genotype given  as follows are possible

PW X WW >  PW , WW , PW , WW

PW will give rise to purple and WW will give rise to white flower.

Chance of white flower being formed will be 50 % ( 2 out of 4 possibilities )

this is a pretty broad question and can be a pretty lengthy answer. since 1900, women have gained a lot more rights and have become active in the workforce. with women being in the workforce, men play a larger role in family life. many family tasks are shared between men and women, whereas, women used to be the sole family caretakers.

that should get you started at least.
