Red eyes are not gender specific and 100% of the offspring

would have red eyes would have red eyes if the gene were on autosome.

Explanation:

If the eye colour is not sex-linked and the traits are on the autosomes.

Genotype for male = XWY or XwY

Genotype for female = XWXW, XWXw. XwXw

Punnet square:

cross between red eye male and white eye male

         XW      Y    

XW XWXW  XWY

XW XWXW  XWY  all oofspring red eye

cross between white eye male and red eye female

           Xw      Y

XW   XWXw  XWY

Xw    XwXw  XwY      1 red male:1 white male: 1 red male : 1 white female

if mother has recessive gene all the male will be white eyed.

all the female progeny will have red eye because father had dominant red eye.

The red eye is dominant over white hence dominant trait will appear.

Why are a plants stomata generally open during the day and closed at night brainly?
bagirrra123 [75]
To keep in the stored enzymes so it can keep synthesizing at night, even when there is no sunlight. -- Stomata serve two main functions - they allow carbon dioxide to reach the cells in the leaf where the majority of photosynthesis takes place and they allow water to be transpired out off the leaf. During the day, stomata are generally open to allow photosynthesis to take place as quickly as possible. At night, when the lack of light means photosynthesis can't take place, many plants close their stomata to reduce water loss. There is one group of mainly desert plants, known as CAM plants, that keep their stomata closed during the day when water loss would be greatest, and open them at night, using a biochemical method to effectively store carbon dioxide in the leaf overnight.
