Answer:

Non disjunction at meiosis I results in formation of two daughter cells with one extra chromosome (n+1) and two daughter cells with one less chromosome (n-1).

Explanation:

Failure of homologous chromosomes to separate from each other by the end of metaphase I leads to nondisjunction. The process forms two types of daughter cells: Two daughter cells with n+1 chromosomes (presence of one extra copy of chromosome) and rest two with n-1 chromosomes (absence of one chromosome from the genome).

The correct answer is: daughter cells will have abnormal chromosome numbers and this condition is called aneuploidy.

Nondisjunction is the failure of homologous chromosomes (or sister chromatids) to separate during the process of cell division and consequently lead to aneuploidy. There are three forms of nondisjunction:  

• Nondisjunction in meiosis I (pair of homologous chromosomes unable to separate in meiosis I),  

• Nondisjunction in meiosis I (sister chromatids unable to separate during meiosis II), and

•  Nondisjunction in mitosis (failure of sister chromatids to separate during mitosis)

An organism has two types of cells: diploid somatic cells and haploid gametes. How does this organism reproduce?
gladu [14]
The correct answer is letter (B) Asexually. <span>An organism has two types of cells: diploid somatic cells and haploid gametes. Diploid somatic cells and haploid gametes reproduce using mitosis. During mitosis, it creates an identical copy of the cell. They are non-sex cells. They are the cells that make up the sex organs, muscles, skins, hair, etc.</span>

Mutation is an important mechanism for evolutionary change. Which type of mutations contribute to evolution?
rodikova [14]
Adaptations are the result of evolution in different living organisms. This process occurs amazingly through gene mutation but it takes a very long period in time. Adaptation processes occur to help species survive and thrive in the ecological balance of life. Structural adaptations are physical features of an organism that adapted through time. An example of this are the bills of a bird and the fur of bears that they generally need for their survival; birds for hunting, and bears to protect them from low climate areas.
<span>
Functional or Behavioral adaptations refer to particular things that an organism or organisms do to survive. In the example above, behavioral adaptations that birds do is through certain bird calls and migration, while bears hunt during warmer seasons and hibernate during winter season. </span>

vladimir2022 [97]

Answer: sporophyte, gametophyte, alternation of generation

Explanation:

Alternation of generation is a kind of life cycle seen in plants and algae in which the diploid asexual and haploid sexual stages exist. A sporophyte is multicellular and diploid which is an asexual stage. It produces the haploid spores through meiosis. The haploid spores germinate to produce haploid gametophyte. The gametophyte produces gametes by the process of mitosis.
