[Incomplete question. I found these data in other source]

Brown: BB and Bb

White: bb

Narrow: LL and Ll

Long: ll

Answer:

This means that long is recessive and narrow is dominant, and also brown is dominant and white is recessive.

root color -> Alleles: narrow (L) and long(l)

leaflets length -> Alleles: brown (B) and white (b)

a) A brown (homozygous) narrow (heterozygous) mandioca is BBLl, so it can produce BL or Bl gametes

A white mandioca is always homocygous, so a white narrow (heterozygous) mandioca is bbLl - this means it can produce bL and bl gametes.

So here is the Punnett square:
---|-- BL-|--Bl--
bL|BbLL| BbLl
-bl|BbLl-|Bbll

So 75% of the offspring will be brown and narrow and 25% will be brown and long.

b) A long mandioca is always homocygous, so a brown (homocygous) long mandioca is BBll – this means it can only produce Bl gametes. As white has to be homobygous as well, a white long mandioca has to be bbll – this means it can only produce bl gametes. So here is the Punnett square:
---|- Bl
bl-|Bbll

So all the offspring is going to be brown and long.
