Question

In snapdragons the inheritance of a lower color of size of leaves are examples of incomplete dominance. When red-flowered plants are crossed with white ones, all the flowers are pink. Similarly, when plants with broad leaves are crossed with plants of narrow leaves, the offspring have intermediate leaves. Cross a homozygous red-flowered, broad-leaved plant with a homozygous white-flowered narrow leaved plant. What kind of offspring are produced in the F1 generation? Now cross two of these plants and find the phenotype ration of the offspring. Explain the relationship of the 9:3:3:1 ration to the one you obtained.

Plz help..this is due monday and im a freshman in H bio and my teacher hates me and i seriously asked for help multiple times but my teach acts like i'm not even there

Answer 1

Well in order understand genetics you have to actually do it. you just make a punit square. From this you have homozygous meaning the red flower should be RR for dominance and rr for white flower for recessive. Same with broad being BB and narrow bb.


should look like this

______R___________ R
r|_________|_____________|
r|_________|_____________|

and
__B______B
b|_____|_______|
b|_____|_______|
then you have the ratios, then do it for the offspring for the F2 generation.

hint* think of it as a multiplication table

Answer 2

Most people who say their teachers hate them don't put forth the required effort needed in the class in the first place and only start to care about their grades when they realize they are going to fail.
