Answer:
<em>Ana-phase 1 of Meiosis 1 in Male Parent...</em>
Explanation:
It is clear that meiosis is only happening in male due to AAa nondisjuction of dominant AA from male parent. The disjunction is occuring during spermato-genesis during Ana-phase 1 of Meiosis 1 cause it is only possible explanation of tri-somy at Chromosome 1...
Answer:
There is no cure for cystic fibrosis, but treatment can ease symptoms and reduce complications.
Explanation:
1). For those with cystic fibrosis who have certain gene mutations, doctors may recommend a newer medication called ivacaftor. This medication may improve lung function and weight, increases the activity of Cystic fibrosis transmembrane conductance regulator (CFTR)protein and reduce the amount of salt in sweat. It has been approved by the Food and Drug Administration for people with cystic fibrosis who are age 6 and older. The dose depends on your weight and age.
2). For people with a certain gene mutation who are age 12 and older, another drug is available that combines ivacaftor with a medication called lumacaftor. This drug is called orkambi.
The use of Orkambi may improve lung function and reduce the risk of exacerbations.
I hope you're clear on this Daxxy
Answer: is heterozygous
Explanation: A hybrid is heterozygous which means that it has one dominant gene and one recessive gene. A dominant gene is a type of gene which has the ability to express itself phenotypically either in a homozygous or a heterozygous state. A dominant gene masks the effect of a recessive gene. A recessive gene is a type of gene that lacks the ability to express itself in a heterozygous state. It can only express itself outwardly in a homozygous state. It's effect is masked by the dominant gene is a heterozygous state.
Explanation:
A single nucleotide-pair substitution missense mutation causes a change of a single amino acid into another. Aa a result, the produced protein will have an almost normal sequence except for one amino acid.
On the other hand, a frameshift mutation changes the Open Reading Frame (ORF) of the ribosome. The ribosome moves along the mRNA every three nucleotides (codons) and translates them into amino acids that will form the nascent protein. If there is a frameshift mutation (an insertion or deletion of a number of nucleotides not multiple of three) the ribosome will "read" the mRNA differently and will identify different codons than the wild-type sequence, so a large number of amino acids will be different in the mutated protein.
