When Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), what were the flower colors of the resulting offspring? 25 percent white and 75 percent purple 50 percent white and 50 percent purple 100 percent purple 100 percent white

Answers

The answer is 100 percent purple

Let P be dominant allele for purple flowers and p recessive allele for white flowers. So purebred purple flower has two P alleles and its genotype is PP and purebread white flower has two p alleles and its genotype is pp. Since P is dominant over p, when found together like in heterozygous plants (Pp), the flowers will express dominant allele and will be purple.
So, a cross between purebred purple flowering plants (PP) with purebred white flowering plants (pp) will have 100% of the offspring with genotype Pp and purple flower color.

Parents:               PP      x       pp
Offspring:        Pp     Pp      Pp    Pp

When Mendel crossed purebred purple flowering plants (PP) with purebredwhite flowering plants (pp), the flower colors of the resulting offspring is: 100 percent purple.

WHAT IS MENDEL CROSS:

  • Gregor Mendel, who is referred to as the FATHER OF GENETICS, crossed pea plants using several of their characters.

  • He crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp) to obtain offsprings that were all purple flowered (Pp).

Therefore, it can be said that when Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), the flower colors of the resulting offspring is: 100 percent purple.

There were 100 new cases of syphilis last year in a given population of 100,000 people. At that time, 500 people in this population already had syphilis. The incidence of syphilis in this population is __________.

a. 100 per 100,000

b. 500 per 100,000

c. 1000 per 100,000

d. 5000 per 100,000

Answer:

a. 100 per 100,000

Explanation:

Incidence rate of a population can be defined as the rate at which an disease occurs in a population.

The incidence of a population is calculated as

The number of new cases ÷ The population of the people

From the above question,

The number of new cases = 100

The population of the people = 100,000

The incidence = 100 ÷ 100,000

The incidence of syphilis in the population is 100 per 100,000

Answer:

100 per 100,000

Explanation:
