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

Responses

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

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

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

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

The correct response is:

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

This statement highlights the importance of gametes being haploid, as their fusion during fertilization results in a diploid organism with the correct number of chromosomes, maintaining the stability of the species' chromosomal count across generations.

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

random distribution.

genetic variation.
genetic variation.

crossing over.
crossing over.

independent assortment.

The correct response is:

independent assortment.

This principle, established by Gregor Mendel, states that the segregation of one gene does not influence the segregation of another gene, assuming the genes are located on different chromosomes.

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.

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 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.

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

The correct response is:

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

During meiosis I, homologous chromosomes are separated, resulting in two haploid cells. Then, meiosis II separates the sister chromatids of those haploid cells, ultimately producing four haploid daughter cells.

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

The correct response is:

crossing-over.

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

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
the passing of genetic information from parents to their offspring

the adaptation of certain individuals that increases their likelihood of survival

The correct response 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.
