What do you call the non-Mendelian inheritance pattern that states that both traits are dominant and both appear in the organism
dangina [55]

Answer:A. Codominance

Explanation:

This is a type of genetic inheritance where neither of the genes is dominant over another. Thus both pair of the gene are expressed on the same LOCUS equally with none masking another. Therefore an   individual receive both  allele of a heterozygous  gene, and have equal phenotypic expression

An example is the AB  blood group in man, where both allele present on the same locus are fully expressed with no one dominant over another.

Incomplete dominance refers to a blend of  alleles where one does  not have  full dominance over another another, therefore gives a new phenotypic expression different from both alleles.

e.g  pink flower allele in four o'clock flower.

In an experiment, a certain colony of bacteria initially has a population of 50,000. A reading is taken every 2 hours, and at th
Iteru [2.4K]

Answer:

1) Recursive definition: p_n = (50,000)3^n

2) At the beginning of the 4th interval

Explanation:

1)

The initial population of the bacteria at time zero is

p_0 = 50,000

Here we are told that the reading is taken every two hours; we call this time interval "n", so

n=2 h

And also, after every time interval n, the number of bacteria has tripled.

This means that when n = 1,

p_1 = 3 p_0

And when n=2,

p_2 = 3 p_1 = 3(3p_0)=9 p_0

Applied recursively, we get

p_n = 3^n p_0

And substituting p0,

p_n = (50,000)3^n (1)

2)

Here we want to find at the beginning of which interval there are

p=1,350,000

bacteria.

This means that we can rewrite eq.(1) as

1,350,000=(50,000)3^n

By simplifying,

27=3^n

Which means that

n=3

However, this means that the number of bacteria is 1,350,000 after 3 time intervals; therefore, at the beginning of the 4th interval.
