Movement of chromosome segment to a non-homologous chromosome. This type of chromosomal mutation occurs when one chromosome swap
Hitman42 [59]

Answer:

The correct answer is ''Translocation​.''  

Explanation:

Translocation is a chromosomal abnormality that is due to a change in position of a chromosomal segment to another non-homologous chromosome of the same nucleus or to another part of it. It is produced by the exchange of segments between two chromosomes without loss of genetic material is called reciprocal or balanced translocation, when it gives rise to monocentric chromosomes.Translocations can be detected cytologically because the structural heterozygote forms a quadrivalent (4-chromosome association) in meiotic prophase. Sometimes they can also be detected by changes in the size of the chromosomes if the exchanged segments are of different lengths.

Dafna1 [17]

Answer:

The genotypes of the two parents: normal head shape (HH) and Bart head shape (hh)

The genotypes in the F1 generation= Hh

The phenotypes present in the F1 generation= All normal head shape

Explanation:

Let's assume that the allele "H" is responsible for the normal head shape while the allele "h" gives Bart head shape. According to the given information, both the parents are homozygous. The genotype of the parent with normal head shape would be "HH" while that of the one with Bart head shape would be "hh". Since the normal head shape is dominant, all the F1 hybrid progeny would exhibit "normal head shape".

marusya05 [52]

Answer:

A) Power plant

Explanation:

The key to understanding this question, is first knowing what "stationary" means. When something is stationary, it doesn't move, it just stays in one place.

Since power plants are buildings, they naturally don't move. On the other hand, the other choices are all vehicles that are intended to move. So while all of these options do cause air pollution, the power plant is the only one that is stationary.

I hope this answer helps you :)
