Explanation / Answer

genotype is the genetic allels that make for example yellow or green pigment. can be either resessive or dominating ( for example, you have a yellow pigment in locus A that is
Dominating, it does not matter what is in the complimentary locus, but if you have resessive pigment white ( no pigment at all) and dominating yellow, its still yellow because it dominates over the resessive

fenotype is what you see (e.g. yellow bean) but can have different Genotypes ( 2 yellow or yellow and white as above)

the parents purple x purple(so that both are hetero zygote = have both allels)
Yy x Yx x means crossing ( mating) of parents
punnet suqare

Y y

Y YY Yy

y yY yy

YY, Yy are purpple and
yy is yellow

Y= purpple
y= yellow
so that purple is dominating

the other is same thing with 1 more allel pair

Y=purpple
y =yellow
W= smoot
w= wrinkle
purpple and smooth are dominating
F1 (parents) genotypes YyWw x YyWw

punnet square
YW Yw yW yw

YW YYWW YYWw YyWW YyWw

Yw YYWw YYww YyWw Yyww

yW YyWW YyWw yyWW yyWw

yw YyWw Yyww yyWw yyww

where all with capital Y and W are smooth purpple
small ww are wrinke
small yy are yellow
