The tiny blue-eyed mary flower is often one of the first flowers seen in the spring in some regions of the united states. the flower is normally blue, but sometimes a white or pink flower variation is found.
the following data were obtained after several crosses.
parents f1 f2
blue × white blue 196 blue, 63 white
blue × pink blue 149 blue, 52 pink
pink × white blue 226 blue, 98 white, 77 pink
(a) the appearance of blue in the f1 generation of the pink and white cross demonstrates that flower color is not an inherited trait but is determined by the environment.
(b) flower color depends on stages of flower development, and young flowers are white, advancing to pink and then blue.
(c) since the f1 and f2 phenotypes of the pink and white cross do not fit the expected genotypic and phenotypic ratios, blue-eyed. mary must reproduce by vegetative propagation.
(d) flower color is an inherited trait, and the f1 and f2 phenotypes of the flowers arising from the pink and white cross can best be explained by another gene product that influences the
phenotypic expression.

Explanation:

the apgar score is 6

here are the 5 factors that are observed when calculating the apgar index:

skin color

blue everywhere - 0 points

white on the ends and pink on the body - 1 point

all pink - 2 points

heartbeat

absent - 0 points

slow - 1 point

fast - 2 points

reflexes

no answer: 0 points

responds to stimulations: 1 point

cries and coughs: 2 points

muscle tone

soft: 0 point

some bending or stretching: 1 point

active movements: 2 points

breathing

absent: 0 points

weak or irregular: 1 point

good and your baby is crying: 2 points

it is estimated that children whose score is between 8 and 10 are in perfect health and need only routine care. a score between 5 and 7 is representative of a fair condition. often this means that the child has suffered during delivery and probably needs with breathing. as a first step, your doctor will carefully rub the skin of your baby or give him oxygen with a mask.
