Vamos aprender mais sobre o ๐๐๐๐๐๐๐๐๐๐๐! 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).
1
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
illustrate the relationships between members of a family
determine the likely pattern of inheritance of a disease
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 affected men who pass the trait only to their daughters
present only women with theย characteristic
present only men with the characteristic
present men and women with the characteristic in the same proportion
4
present only women with theย characteristic
the parents have recessive genes for that trait
that the mother is recessive and the father is dominant for that trait
that father and mother are heterozygous for that trait
that the mother is heterozygous and the father is recessive for that trait
5
Of the following alternatives which does NOT have a type of natural selection.
directional selection
stabilizing selection
disruptive selection
dimensional 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 ?
phenotype
genetics
ovum
mendel
8
Chromosomes of each pair (maternal and paternal)
homologos
homozygous
genotype
spermatozoon
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
my home country
family genealogy
