Answer:

The answer is a) gene flow

Explanation:

Gene flow is any displacement of genes from one population to another. The gene flow includes a multitude of different types of events, such as pollen that is transported by air to a new destination or people who move to another city or another country. If genes are transported to a population where those genes did not exist, gene flow can be a very important source of genetic variability.

.. Which of the following mutations would have the potential to affect future generations of
ch4aika [34]

Answer choices:

  • A frame shift mutation in the X chromosome of a cheek cell
  • A chromosomal mutation in the Y chromosome of a kidney cell
  • A point mutation in the first chromosome of a sperm cell
  • A substitution mutation in the third chromosome of a uterus cell

Answers:

A point mutation in the first chromosome of a sperm cell

Explanation:

Only mutations that affect the germ line are passed on to the next generation. Therefore, only mutations in the egg and sperm of an individual have the potential to affect the next generation.

Mutations in cheek cells, kidney cells, and uterus cells might cause cell death or cancer. This genetic material is not passed on to the next generation, only the egg and sperm contribute this material. Therefore, only mutations here will affect the generation.

What are the limitations of sending information using electromagnetic waves?
Shalnov [3]
Well, the range is more limited. Let's say if you tried listening to Denver radio all the way in Texas, you wouldn't be able to listen to it.

Another one is that other electromagnetic waves with similar frequencies can interfere with each other

Suppose the human trait for hair type is controlled by a simple dominant and recessive relationship at one locus. Curly hair, C,
myrzilka [38]

Answer:

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461

Explanation:

Given -

Curly hair, C, is the dominant allele, and straight hair, c, is the recessive allele

Number of students with curly hair is 37

Thus frequency of genotype "CC"

= q^{2} = \frac{37}{117} \\= 0.3162

Thus, frequency of allele "q"

= \sqrt{0.3162} \\= 0.5623

As per Hardy Weinberg's first  equation-

p+q=1

Substituting the value of q, we get -

p+0.5623=1\\p= 0.4376

As per Hardy Weinberg's second equation -

p^2+q^2+2pq=1\\

Substituting the values of "p" and "q" we get -

0.4376^{2} + 0.3162+2pq = 1\\2pq = 0.2461\\

Hence,

A) The frequency of the dominant allele, C = 0.4376

B) frequency of the heterozygous genotype, Cc = 0.2461
