the inheritance pattern of the Mic2 gene is the same as the inheritance pattern of a gene located on autosome even though the Mic2 gene is actually located on the sex chromosomes

inheritanace pattern which involves genes that are not located in the cell nucleus
4/53
chloroplast DNA, chloroplast are a type of plastid that make chlorophyll, a green photosynthetic pigment
5/53
when the gene function is abolished by creating an organism that is homozygous for a loss-of-function allele
6/53
a pattern in which the genotype of the mother directly determines the phenotype of her offspring (an inheritance pattern for certain nuclear genes)
7/53
a phenomenon when only one allele of a gene is expressed
8/53
an allele is dominant in one sex but recessive in the opossite sex
9/53
alleles which may kill the organism only when certain environmental conditions prevail
10/53
when the alleles of one gene mask the phenotypic effects of the alleles of another gene
11/53
how the allelic variants of two different genes affect a single trait
12/53
the presence of more than one type of organellar genome within a cell or individual

Gene modifier affect
14/53
few genes which are located only on Y chromosome

is an evolutionary theory that explains the origin of eukaryotic cells from prokaryotes
16/53
the genetic material that is found in mitochondria. Mitochondria are structures that convey the energy from food into a form that cells can use
17/53
the attachement of a methyl group onto a cytosine base – is a common way that eukaryotic genes may be regulated
18/53
multiple effects of a single gene on the phenotype of an organism
19/53
a condition in which phenotype is intermediate between the corresponding homozygoes individuals
20/53
is an evolutionary theory that explains the origin of eukaryotic cells from prokaryotes
21/53
the trait occurs in only one of the two sexes
22/53
certain lethal alleles which act only in some individuals
25/53
a second mutation that reverses the phenotypic effects of a first mutation
26/53
Simple Mendelian inheritance
27/53
Monoallelic expression
28/53
inheritance of characters transmitted through extranuclear elements (as mitochondrial DNA) in the cytoplasm of the egg
29/53
compensation by random X-inactivation, of the dosage of gene material in the cells of males and females carrying X-linked genes
30/53
the epigenetic phenomenon by which certain genes are expressed in a parent-of-origin-specific manner. If the allele inherited from the father is imprinted, it is thereby silenced, and only the allele from the mother is expressed.
31/53
organelle where genetic material of mitochondria and chloroplasts is located
33/53
the age when the symptoms of the disease appear
35/53
in each somatic cell of a normal female, one of the X chromosomes is randomly deactivated. This deactivated X chromosome can be seen as a small, dark-staining structure in the cell nucleus
36/53
Genetic polymorphism
37/53
region that is located near the imprinted gene
38/53
it effects the choice of the X chromosome to be inactivated
39/53
how the allelic variants of two different genes affect a single trait
40/53
X-inactivation (also called lyonization) is a process by which one of the two copies of the X chromosome present in female mammals is inactivated
41/53
the mechanism of X inactivation
42/53
a second cross in which the sexes and phenotypes are reversed
43/53
Sex influenced inheritance
44/53
that has the potential to cause the death
45/53
the copies which are not identical due to the accumulation of random changes during evolution
46/53
the allele causing the disease is recessive and located on the x chromosome
47/53
when two alleles are both expressed in the heterozygous individual
48/53
a pattern in which a modification occurs to a nuclear gene or chromosome that alters gene expression, but is not permanent over the course of many generations
49/53
when one of the two x chromosomes is turned off
