Why is it important for gametes to be haploid?(1 point)

Question

Responses

They fuse to form a diploid organism so that there is the expected number of chromosomes.
They fuse to form a diploid organism so that there is the expected number of chromosomes.

Neither parent has the full set of genetic information so each must contribute their half.
Neither parent has the full set of genetic information so each must contribute their half.

When gametes are made, the diploid cell splits twice, creating four haploid organisms.
When gametes are made, the diploid cell splits twice, creating four haploid organisms.

It is impossible for them to be diploid because reproduction does not result in diploidy.

Answer 1

The correct response is:

They fuse to form a diploid organism so that there is the expected number of chromosomes.

This is important because when two haploid gametes (one from each parent) fuse during fertilization, they create a diploid zygote with the full set of chromosomes, which is necessary for the organism's development.

Answer 2

Question
The inheritance pattern of one gene will not affect the inheritance pattern of another gene. This is known as(1 point)
Responses

independent assortment.
independent assortment.

random distribution.
random distribution.

genetic variation.
genetic variation.

crossing over.

Answer 3

The correct answer is:

independent assortment.

This principle states that the inheritance of one gene does not affect the inheritance of another gene, particularly when the genes are located on different chromosomes.

Answer 4

Which of the following is a difference between phase I and phase II of meiosis?(1 point)
Responses

Genetic variations can only occur during phase II of meiosis.
Genetic variations can only occur during phase II of meiosis.

Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.
Phase I results in daughter cells with 23 chromosomes each and phase II with 46 chromosomes each.

Anaphase, metaphase, and telophase only occurs during phase I of meiosis.
Anaphase, metaphase, and telophase only occurs during phase I of meiosis.

Phase I results in two haploid daughter cells and phase II results in four haploid daughter cells.
Phase I results in two haploid daughter cells and phase II results in four haploid daughter cells.

Answer 5

The correct answer is:

Phase I results in two haploid daughter cells and phase II results in four haploid daughter cells.

In meiosis I, homologous chromosomes are separated resulting in two haploid cells, while meiosis II separates the sister chromatids, ultimately resulting in a total of four haploid daughter cells.

Answer 6

During meiosis, non-sister chromatids may exchange sections of DNA leading to genetic diversity. What is this process called?(1 point)
Responses

karyotypes
karyotypes

nondisjunction
nondisjunction

independent assortment
independent assortment

crossing-over

Answer 7

The correct answer is:

crossing-over.

This process occurs during prophase I of meiosis when non-sister chromatids exchange segments of DNA, leading to genetic diversity in the resulting gametes.

Answer 8

What is heredity?(1 point)
Responses

the adaptation of certain individuals that increases their likelihood of survival
the adaptation of certain individuals that increases their likelihood of survival

the exchange of genetic information to create new variation
the exchange of genetic information to create new variation

the random distribution of chromosomes to produce new genetic combinations
the random distribution of chromosomes to produce new genetic combinations

the passing of genetic information from parents to their offspring

Answer 9

The correct answer is:

the passing of genetic information from parents to their offspring.

Heredity refers to the process by which traits and characteristics are transmitted from parents to their offspring through genes.
