A. Both parents are heterozygotes
B. An offspring is a heterozygotes
C. The next three offspring will be phenotypically unaffected
D. Any two out of three offspring will be phenotypically unaffected.
If lacI is binding the lacO, lacZ will be transcribed
Explain independent assortment using a dehybrid Tex cross
Explain independent assortment in a genetic cross between two parents that are heterogynous for plant height and seed shape
The child was born in a closely related marriage (children of sisters). Height at birth 50 cm, weight 3,000 g, screamed and took the breast immediately. Psychomotor development is delayed. He was constantly under the supervision of a pediatrician, received a massage.
According to the parents, the patient complains of shortness, problems when walking. During the examination, it was found: height 76.0 cm, weight-10.8 kg.The growth zones are open, all the phalanges of the fingers are narrowed, shortened.
1. Your presumptive diagnosis. Justify your answer.
2. Using the OMIM database, determine the locus of the gene responsible for the development of this disease and explain the etiology.
3. Determine the type of inheritance of this disease, characterize it. Determine the possible genotypes of the parents and the child.
4. Determine the causes of this disease.
5. Name the methods used to diagnose this disease.

In Persian cats, the allele for long hair is dominant. If all the Persian cats are born with
long hair, (A) What are the two possible genotypes of the parents? (B) If the offspring of
the first cross results with 3⁄4 long haired while 1⁄4 are short haired. Can you now determine
the exact parents?
Jeffrey Mitton and his colleagues found three genotypes(R2R2,R2R3 and R3R3)at a locus encoding the enzyme peroxidase in Penderosa pine tree growing at Glacier Lake,Colorado.The observed number of genotypes were:
Genotype

R2R3
R3R3
Number observed
135
44
