My biology curriculum isn't reliable so I need to ask questions here

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

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

B) They fuse to form a diploid organism so there is the correct number of chromosomes.

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

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

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

A) crossing over.

B) genetic variation.

C) random distribution.

D) independent assortment.

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

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

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

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

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

4 What is heredity?(1 point)

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

B) the passing of genetic information from parents to their offspring

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

D) the exchange of genetic information to create new variation

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

A) karyotypes

B) independent assortment

C) nondisjunction

D) crossing-over

1. It is important for gametes to be haploid because: B) They fuse to form a diploid organism so there is the correct number of chromosomes.

2. When the inheritance pattern of one gene doesn't affect the inheritance pattern of another gene, this is known as: D) independent assortment.

3.  A difference between phase I and phase II of meiosis is: B) Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.

4. Heredity simply refers to: B) the passing of genetic information from parents to their offspring.

5. During meiosis, sister chromatids may exchange sections of DNA leading to genetic diversity in a process called: D) crossing-over.

Gametes are also known to as sex cells and they can be defined as the reproductive cells that are found in a living organism.

  • It is important for gametes to be haploid cells is because when the sperm and the egg fuse to form a diploid organism, the living sex cells will have 46 chromosomes.

Independent assortment refers to a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.

During meiosis, two (2) diploid daughter cells are formed in phase I while four (4) haploid daughter cells are formed in phase II.

Heredity can be defined as the transfer of genetic information (traits) from the parents of a living organism to their offspring, either through sexual reproduction or asexual reproduction.

Some examples of hereditary traits are:

  • Dimples.
  • Baldness.
  • Height.

During meiosis, crossing-over makes it possible for sister chromatids to exchange sections of deoxyribonucleic acid (DNA) which leads to genetic diversity.
