The 2 basic functions of meiosis are to

Maintain chromosome number through generations

Cause genetic variations by recombination.
stira [4]3 years ago

Answer:

The correct answers would be maintain chromosome number through generations  and cause genetic variations by recombination.

In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.

It helps in the formation of gametes in sexually reproducing organisms.

These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.

In absence of meiosis, the chromosomal number would have doubled after each generation.

In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.

During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.

padilas [110]
The green house effect occurs when carbon dioxide and water vapor form an invisible blanket around the globe that allows the sun's light to enter, but traps the heat. Green house effect is a process that warms the Earth's surface. When the sun's energy reaches the Earth's atmosphere, some of it is reflected back to the space and the rest is absorbed and re-radiated by greenhouse gases.

If a homozygous black bull is mated with a homozygous white cow and the calf is gray, this would be an example of ________. howe
I am Lyosha [343]

The first statement above is an example of incomplete dominance. If the calf has black and white spots then that’s an example of codominance.

 

Incomplete dominance is a form of transitional inheritance in which one allele for an explicit trait is not entirely expressed over its paired allele. This effects in a third phenotype in which the expressed physical trait is a mixture of the phenotypes of both alleles.

 

Codominance<span> is a form of dominance by which the alleles of a gene pair in a heterozygote are wholly expressed. This effects in offspring with a phenotype that is neither dominant or recessive. A usual example showing this type of dominance is the ABO blood group system.</span>
