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:
illustrate the relationships between members of a family
determine the likely pattern of inheritance of a disease
predict the frequency of a genetic disease in a population
reporting, in a simplified way, family stories
2
The analysis of the pedigree allows us to deduce that the most likely inheritance of muscular dystrophy is:
X-linked dominant
X-linked recessive
X-linked dominant
restricted to Y
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 men with the characteristic
present only women with the characteristic
present men and women with the characteristic in the same proportion
present affected men who pass the trait only to their daughters
4
present only women with the characteristic
that the mother is heterozygous and the father is recessive for that trait
that the mother is recessive and the father is dominant for that trait
the parents have recessive genes for that trait
that father and mother are heterozygous for that trait
5
Of the following alternatives which does NOT have a type of natural selection.
disruptive selection
dimensional selection
directional 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
complete dominance
polygeny
gene interaction
7
Are The characteristics controlled by The genotype and environmental conditions ?
ovum
phenotype
genetics
mendel
8
Chromosomes of each pair (maternal and paternal)
spermatozoon
genotype
homologos
homozygous
9
Heredograms are used to analyze the pattern?
of inheritance of a particular characteristic in a family
to know what state i'm from
to know about my blood type
10
To assemble a pedigree, specific symbols are used that represent the?
my children
