Why is meiosis important for organisms

musickatia [10]

Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination. Meiosis is important because it produces gametes, female or male germ cells.

Phoenix [80]

Answer:

A) allopatric speciation

Explanation:

Allopatric speciation is a type of speciation that is caused due to geographical isolation that results in the separation of the population of the same species that once inhabited the same geographical area.
Due to this geographic separation, the species become so isolated that no more gene flow occurs between the two species and therefore, with time new species get formed.
The various geographic changes that can contribute to the separation of the two species can be - formation of mountains, islands, water bodies, glaciers, etc.
The populations that get separated due to the geographic barriers are subjected to different selective pressures and hence, speciation occurs.

Cross a person who does not have freckles and is heterozygous for dimples with a person who has

Alja [10]

Answer:

1. 1/2

2. 1/2

3. 1/4

Explanation:

Let the allele for freckles be A or a while that of dimples be B or b.

A person without freckles but heterozygous for dimples = aaBb

A person who has freckles (whose mother has no freckles) but no dimples = Aabb

aaBb x Aabb

Offspring

4 AaBb - freckled and dimpled

4 Aabb - freckled and non dimpled

4 aaBb - non freckled and dimpled

4 aabb - non freckled and non dimpled

1. Probability that the parents will have a dimpled child = 8/16 or 1/2

2. Probability that they will have a child with freckles = 8/16 or 1/2

3. Probability that they will have a child with freckles and dimples = 4/16 or 1/4
