Answer:
Their future children can have blood group AB, O, A or B
Explanation:
since the husband had blood group= Heterogeneous A means AO
and,
the wife's blood group= Heterogeneous B or BO
- so by crossing between them, we get this result.
A. Natural Selection. This is because the weeds that are not resistant to it die out before they can reproduce, but the resistant ones grow to maturity and then reproduce, passing down the resistance gene. Over time, the resistance gene would become a normal thing in weeds, while the non-resistant gene would not exist anyone, since the gene could not be passed on.
Answer:
Explanation:
1. The DNA: the DNA is the template from which the mRNA is produced, ie the non coding template strand of one of the two DNA strand is utilized in transcription.
2. The mRNA determine the amino acid sequence of protein. After the production of mRNA from the DNA, the mRNA is then utilized to carry out translation which involve the synthesis of polypeptides: chain of amino acids.
3. The tRNA aids in translation by care the amino acid read on the mRNA and also carrying the complimentary anticodon to match the codon for the amino acid on the mRNA.
4. THE rRNA also known as the ribosomal RNA is what makes up the one of the main component of the ribosomes. A major part also helps in the period bond formation
Answer:
If all frogs were to die off, a valuable food source will go missing in the food chain of many animals around the world after that the number of animals that eat the frogs will die off, then the animals that eat them will go hungry, and their populations will be devastated as well.
we can say that (F) is the dominant healthy gene and (f)is the recessive anemia gene
Falconi anemia is a recessive autosomal disease, therefore it will affect men and women equally
1)Arlene's genotype is (ff)
2)Ann's genotype is (Ff)(she's a carrier). Michael's genotype is (Ff)(also a carrier)
3)George's genotype is (Ff)
4)Sandra's genotype is, most likely (FF)
5)Sam, Ann and Michael are most likely carriers.
