Genotype j- Mid-digital your fingers. Notice that each finger is divided into three segments The middle segment is called the mid-digit segment. Examine your mid-digit segments for the presence of hair. If most of the mid-digits lack hair, then you have hairless mid-digits. If most have hair, then you have hairy mid-digits. Hairy mid-digits are dominant over hairess mid digits. M hairy mid-digits, m hairlcss mid-digits. Genotype I-left k.

C no Cleft Genotype
Explanation / Answer
A. When I held my hands facing towards my face, my little fingers were bending towards the ring fingers. So I have bend little finger. The genotype for bend little fingers is BB or Bb.
B. I do not widows peak. So if the widows peak is dominant character, I have recessive alleles. The genotype of the following character is pp.
C. I have brown eye color. Since it is a dominant feature the genotype of this character is CC or Cc.
D. I have dimples on my cheeks and since it is a dominant character my genotype is DD orDd.
