Sexually-reproducing species have an advantage over asexually-reproducing species in their ability to
maw [93]

The sexual reproduction helps in having more variation among the offsprings. It also makes the offsprings more resistant to genetic diseases.

<h3><u>Explanation</u>:</h3>

Sexual reproduction is the process by which the gametes of the species fused together to form zygote which develops into an offspring. This offspring produced has the gene from both the parents . This genetic setup is not only copied from the parents but they undergo the crossing over and independent assortment which leads to variation among the offspring itself as well as they differ from their parents too.

This variation among the offspring as well as the crossing over helps to eleminate the lethal genes from the genetic pool. Thereby they help to get more resistance among the offsprings from diseases.

Answer:

E) horizontal gene transfer

Explanation:

Horizontal gene transfer can also be referred to as lateral gene transfer. It is the transmission of deoxyribonucleic acid (DNA) between different genomes.

Horizontal gene transfer has been shown to occur between different species, such as between prokaryotic and eukaryotic organisms.

Horizontal gene transfer is made possible by the existence of genetic elements, such as plasmids, transposons, and bacteriophages (bacteria that infects viruses).

When a germ cell undergoes meiosis, which event would MOST likely result in four aneuploid daughter
sveta [45]

Answer:

B. misalignment of the chromosomes during anaphase I

Explanation:

Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.

When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.
