Vamos aprender mais sobre o 𝐇𝐄𝐑𝐄𝐃𝐎𝐆𝐑𝐀𝐌𝐀! What is a pedigree? Heredograms are graphical representations of kinship relationships between individuals. Through this tool it is possible to observe, for example, the transmission of hereditary characteristics such as eye color between different generations, as well as diseases of autosomal origin (caused by alterations in the autosomal chromosomes) and sexual (caused by alterations in the sex chromosomes).

It is INCORRECT to state that the analysis of pedigrees can:
predict the frequency of a genetic disease in a population
reporting, in a simplified way, family stories
determine the likely pattern of inheritance of a disease
illustrate the relationships between members of a family
2
The analysis of the pedigree allows us to deduce that the most likely inheritance of muscular dystrophy is:
restricted to Y
X-linked dominant
X-linked dominant
X-linked recessive
3
Heredograms are representations of kinship relationships between individuals. Through it, we can discover, for example, whether a trait is X-linked or autosomal. If a trait is X-linked, the pedigree should:
present only women with the characteristic
present men and women with the characteristic in the same proportion
present only men with the characteristic
present affected men who pass the trait only to their daughters
4
present only women with the characteristic
that father and mother are heterozygous for that trait
that the mother is recessive and the father is dominant for that trait
that the mother is heterozygous and the father is recessive for that trait
the parents have recessive genes for that trait
5
Of the following alternatives which does NOT have a type of natural selection.
directional selection
dimensional selection
disruptive selection
stabilizing selection
6
Pairs of genes, with independent segregation, can act together to determine the same phenotypic characteristic. This phenomenon is known as:
epistasis
polygeny
gene interaction
complete dominance

Heredograms are used to analyze the pattern?
