Explanation:
<u>D. 6</u>
There are two forms of the gene, CTGT and TGTC, called alleles. These have undergone 3 crossover events, which may create two separate copies.
Thus 2 × 3 (# of events)= 6 new alleles
The interchange of chromosome segments, including homologous non-sister or identical chromatids. Crossing over happens at chiasmata, where non-sister chromosomes are fused together.
Further Explanation:
DNA variants on chromosomes,may have different forms called alleles. DNA, which is a genotype, is transcribed into mRNA and then converted into amino acids that are linked together by rRNA to form proteins that make up the morphology of the individual.

I believe that most mature soils have three soil horizons. That is Horizon A, Horizon B, and Horizon C. Horizon A, also called the top soil contains a mixture of mineral matter and organic matter, as well as many insects, fungi, and microorganisms. Horizon B, also called the sub soil, contains fine clay particles washed out of horizon A. Horizon C contains partially weathered parent material.
Answer:
All cells except sex cells
Explanation:
The sperm will be immature and sperm count will be lower if the bulbourethral gland in males fails to perform its function
The bulbourethral gland or Cowper's gland, which is homologous to the Bartholin's gland in females, produces pre-ejaculate that cleanses and lubricates the urethra prior to the arrival of the semen.
The Cowper's glands or bulbourethral glands produce the first fluid that leaves the urethra in order to neutralize the acid left from the urine. The sperm like a basic or alkaline environment in order to survive. If the function of the Cowper's glands or bulbourethral glands fails to perform its function then the sperm will not get a proper medium to travel and will get diminished in the urethra and the sperm count will get reduced.
