Introns because they are coding sequences.
Exons because they are non-coding sequences.
Answer:
given, mother and father are heterozygotes.
let, father has B blood group and mother has A blood group.
then their heterozygous genotypes are --
father = iB, iO and mother = iA, iO
punnett square will be,
iB iO
iA iA iB iA iO
iO iB iO iO iO
the genotypes of their progeny will be, iAiB , iAiO ,iBiO and iOiO
and phenotypes will be 3 are heterozygous and 1 is homozygous.
The flooding of half part of the forest have successful separate the population of frogs in that ecosystem into two different set of frogs. This is an example of allopatric speciation, that is, the population become separated as a result of geographical barrier. This separation will make the two set of frog population to become new species. On the long run, the two species may become unable to relate sexually.
Answer: His genes contain a mutation that prevents red blood cells from proper functioning.
Explanation:
Hereditary anaemia is a type of disorder that are genetically transmitted to the offsprings by the parents . These type of anaemia are inherited from the parent including sickle cell anaemia.
The offsprings inherent Gene mutation that cause abnormalitiies. They inherit abnormal haemoglobin that can reduce the life span of red blood cells thereby affecting their proper functioning of carrying oxygen in the blood, leading to anaemia.
