Human growth is controlled by several pairs of unlinked genes. If we neglect environmental factors and conditionally limit ourselves to only three pairs of genes, then we can assume that in some population the shortest people have all recessive genes and height 150 cm, the tallest - all dominant genes and height 180 cm.

Tasks:

1. Determine the genotypes of the family and their children, with a wife's height of 155 cm, with a husband's height of 175 cm

2. What kind of gene interactions does this inheritance refer to? Describe!

3. Give 3 examples of this type of gene interaction


A woman with black eyes marries a black-eyed man. One blue-eyed child was born from this marriage.


Questions:

1) Determine the genotypes and phenotypes of all family members and the likelihood of having a blue-eyed baby. Describe the type of inheritance?

2) What Mendel's law is observed in this case? Why?

3) Give 5 examples of human diseases with this type of inheritance.



If a blue eyed offsprings is formed from black eyed parents, what type of chararacyer the blue eye is dominant or recessive? Write with reason? Also give a chart?

3. The pediatrician of the maternity hospital examined the child and found that the anus was missing. The child was urgently sent to the pediatric surgical department.

Questions:

1. What cellular mechanism of ontogenesis is likely to be disturbed?

2. Name, are there any other mechanisms?

Blind girl, parents, brothers and sisters who were also blind, was married to a blind boy, a brother and sister who were also blind, and the other members of the family - mother, father, two sisters and a brother - sighted. From this marriage, 8 sighted children were born. Analyze the pedigree and name the reason for the birth of sighted children in blind parents.


Hypertrichosis is inherited as a trait linked to the Y-chromosome, which manifests itself by 17 years of age. One of the forms of ichthyosis (scaly, patchy thickening of the skin) is inherited as a recessive trait linked to the X chromosome. In a family where the woman is normal, and the husband has only hypertrichosis, a boy was born with signs of ichthyosis.

a) Determine the likelihood of this boy showing hypertrichosis?

b) Determine the probability of birth in this family of children without anomalies and what gender will they be?
