In humans, six fingers (f) is the dominant trait; five fingers (f) is the recessive trait. if the father is heterozygous for six
rodikova [14]

The probability of the offspring of a heterozygous father and homzygous mother having five fingers is 50%.

<h3>How to calculate genotype of a cross?</h3>

According to this question, a gene coding for the number of fingers in humans is involved. The allele for six fingers (F) is the dominant trait while the allele for five fingers (f) is the recessive trait.

If a cross between a heterozygous father that posseses a genotype of Ff and a homzygous mother that posseses a genotype of ff, the following offsprings will be produced:

  • Ff
  • Ff
  • ff
  • ff

This shows that the probability of the offspring of a heterozygous father and homzygous mother having five fingers is ½ (50%).

Given that a virus divides every 3 hours, and that a cell lyses (explodes) after it reaches a viral load of 5,000,000 units, how
vladimir2022 [97]

The replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.

<h3>How to calculate the Exponential growth/decay formula?</h3>

x ( t ) = x 0 × (1 + r ) t

  • x(t) is the value at time t.

  • x 0 is the initial value at time t = 0.

  • r is the growth rate when r/ 0 or decay rate when r < 0, in percentage.

  • t is the time in discrete intervals and selected time units.

Whit this information, we can conclude that the replication time for a virus starting at 1,500 units to lyse the cell is 5 hours.
