Asked by John
Genes:
Brown = B
Big eyes = E
Small ears = S
Frizzy hair = F
These 4 phenotypes B, E, S, F are dominant. Recessive alleles = b, e, s, f
Assume that all 4 genes are present on the same chromosome and
1) Be/bE and be/be resulted in 400 Be/bE, 300 be/be, 200 bE/be, and 100 Be/be progeny
2) SF/sf and sf/sf resulted in 200 SF/sf, 100 sf/sf, 400 Sf/sf, and 300 sF/sf progeny
3) Es/eS and es/es resulted in 200 Es/es, 350 es/es, 250 Es/es, and 200 eS/es progeny
List the possible positions of "F" on the chromosome.
Can anyone assist me with this? Readings or how to start would be great. Thank you in advance.
