Answer:

50% of getting A blood type

Explanation:

Using a punnet square you have (sorry cant do a square)

 <u>   IA            IB</u>

<u />

<u>IA</u>

<u />

<u />

<u>i</u>

<u />

Then you you add all the possible combinations from both parents genes

              IA               IB

IA          IA IA           IA IB

i            IA i               IB i

You now have a 50% chance of A type blood because the lowercase (i) wont change the blood type outcome because the IA over shines it.

galben [10]

Answer:

100%

Explanation:

This question involves two genes in guinea pigs; one coding for fur color and the other for fur length. The alleles of black fur (B) and short fur (F) is dominant over the alleles for brown fur (b) and long fur (f).

In a cross between two offsprings with genotypes: BBFF x bbff, the following gametes will be produced by each parent:

BBFF - BF, BF, BF, and BF

bbff - bf, bf, bf, bf

Using these gametes in a punnet square (see attached image), one will notice that all of the offsprings will have the genotype: BbFf i.e all or 100% of the offsprings are heterozygous for both of the genes or traits.

Helicases to be termed as enzymes that is blind and contains acid i.e. remodel nucleic or have protein i.e. nucleic acid. It is important as the time of DNA replication as it divided the DNA i.e. double stranded into one single standard that permits each and every strand for copied it

Also it cracks the bonds i.e. hydrogen that lies between the two strands this could create a replication fork.
