olya-2409 [2.1K]
Given that an average human has a heart rate of 70 beats per minute and if one is to have a 70 year life span, the number of times it will beat is 2,575,440,000 times. This was computed by multiply 70 years by 365 days/year x 24 hours/day x 60 minutes/hour x 70 beats/min. Thus, the heart will beat numerous times before it finally stops.

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.
