Answer:

The correct answer is - random mating individuals pair by chance, not according to their genotypes or phenotypes.

Explanation:

Hardy-Weinberg equilibrium explains that if there are no other evolutionary influences on the population then the frequency of genotype in a specific population remains constant over generations.

The assumptions according to this principle are mention as follow -

-No natural selection.  

-no mutation.  

-The population size should be large.  

-There should be random mating  

-No gene flow.

The correct answer is - random mating individuals pair by chance, not according to their genotypes or phenotypes.

Climate change in the form of global warming (an abiotic factor) has slowly decreased habitat for the arctic seals. What are the
almond37 [142]

The limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

<h3>What is population dynamics?</h3>

Population dynamics is the part of ecology that studies the variations in the occurrence of individuals of the same species (population) and seeks to define the cause of these variations.

Example: with the hunting of alligators, there is an increase in the population of piranhas, thus resulting in a variation of occurrence.

With this information, we can conclude that the limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

Are the excretory system and urinary system the same
balandron [24]
The excretory and urinary are not the same because the excretory system is collective for all system performing the function of eliminating waste from the body like excess water,urea, carbon dioxide and lactic acid but the urinary system focuses on removal of excess water and urea from the body

A man and his wife both have normal color vision, however their daughter is positive for red-green color blindness. The man sues
mixas84 [53]

Answer:

Man's genotype: XᴮY

Woman's genotype: XᴮXᵇ

Daughter's genotype: XᵇXᵇ

The daughter is not the man's child.

Explanation:

Color blindness is a sex-linked trait caused by a recessive allele located in the X chromosome (Xᴮ=normal vision; Xᵇ-color blind).

Women have two X chromosomes, while men have an X and a Y chromosomes. For that reason, women need to have two recessive alleles to be color blind, while men only need one Xᵇ to be colorblind.

Since the man has normal color vision, his genotype would be XᴮY.

If the daughter is her father's, she would have inherited his dominant Xᴮ allele, so she would have normal vision. However, she is colorblind, so her genotype is XᵇXᵇ. She is not the man's daughter.

The mother also has normal color vision, but her daughter inherited a recessive allele from her, so her genotype is heterozygous XᴮXᵇ.
