Patrick , who is In starfish, pink boy color(P) is dominant to orange(p) , and thick eyebrows(T) are dominant over thin(t) ones. Patrick , who is heterozygous for body color but purebred for thick eyebrows , has met Patti , who is recessive for both traits. for body color but purebred for thick eyebrows , has met Patti , who is recessive for both traits. show the cross

Answer 1

Step-by-step explanation:

From the given information;

Pink boy color = P = dominant

orange boy color = p = recessive

Also; for eyebrows:

thick eyebrows (T) is dominant over thin eyebrow t i.e. (recessive)

However, if Patrick = heterozygous for body color i.e. Pp but purebred for thick eyebrow, i.e. TT crosses with;

Patti who's recessive for both traits,

i.e. pp for body color and tt for thin eyebrow.

Then the punnett square cross can be computed as follows:

For Patrick :

Pp × TT = PT PT pT pT

For Patti

pp × tt = pt pt pt pt

PT PT pT pT

pt PpTt PpTt ppTt ppTt

pt PpTt PpTt ppTt ppTt

pt PpTt PpTt ppTt ppTt

pt PpTt PpTt ppTt ppTt
