Answer:

D. 1/64

Explanation:

The desired genotype for the progeny = aabbcc (homozygous recessive for all the three loci). The probability of getting a progeny with a homozygous recessive genotype can be calculated during the product rule.  

The parent genotypes= AaBbCc x AaBbCc

Aa x Aa = 1/4 AA: 1/2 Aa: 1/4 aa

Bb x Bb = 1/4 BB: 1/2 Bb: 1/4 bb

Cc x Cc = 1/4 CC: 1/2 Cc: 1/4 cc

Therefore, the probability of getting a progeny which is homozygous recessive for all the three traits (aabbcc)= 1/4 aa x 1/4 bb x 1/4 cc = 1/64

Which two kinds of information can scientists gather using radar?
makkiz [27]

The correct answers are C. Amount of rainfall, and D. Wind speed.

Explanation

Radars are instruments that were created by humans to detect objects, people, places, among others, through signals. Radars are devices used in different fields such as war, aviation, climatology, geography, among others. One of the best known is the Doppler radar, which is a climatological tool that is used to detect the intensity, size, quantity, and direction of rainfall. Likewise, rainfall is influenced by the direction and speed of the wind, data that can also be obtained using this tool. One of the purposes for which this object was created was the early detection of natural phenomena related to rains, and winds such as hurricanes, electric storms, hail, among others. Therefore, the two objects that scientists can obtain with a radar are C. Amount of rainfall, and D. Wind speed.

Gametes are formed and the chromosome number is reduced in this type of cell division
Anna [14]

Answer:

Meiosis is a type of cell division in which gametes are formed and number of chromosome is reduce i. e. from double to half.

Explanation:

Meiosis cell division only occurs in sex cells of male and female. In meiosis, the parent cell that is diploid i. e. double number of chromosomes, is divided into four daughter cells having half number of chromosome each i. e. haploid or monoploid. These cells are responsible for the variation that occurs in the living organisms.
