Normal development in tests requires a temperature. cremaster muscle contract or relax to move testes toward or away from the body or to maintain the acceptable temperature for testicular.
The body temperature regulation is controlled by the autonomic nervous system under the guidance of medulla oblongata which is in the brain system.

Answer:

The temperature in testicles is controlled by their location and scrotum (its muscle layers)

Explanation:

The testicles in male body is located outside their body. This is so because it regulates the temperature requirement of testicles to produce spermatozoa and male hormone testosterone is sufficient amount. Since testicle is located outside the body, its normal temperature is 4 to 5 degree lesser than the normal body temperature. Also the scrotum covering the testicles also regulate the temperature for optimum spermatozoa development. There are three layers in a scrotum that helps controlling the temperature –

a) Tunica dartos (located inside the scrotum) – This layer is temperature sensitive. It relaxes when hot and contracts when cold

b) Cremaster muscle in the spermatic cord – Based on environmental temperature it regulates proximity of testicle to the body

c) Pampiniform plexus – It is the coil of testicular veins that cools the arterial blood entering the testicle

parasitic plant = A parasitic plant is one that survives at the expense of another, often living and growing on and over the host plant, while siphoning off the other plant’s nutrients and water, and sometimes blocking access to sunlight.

insecticide plant = Insecticide, any toxic substance that is used to kill insects. Such substances are used primarily to control pests that infest cultivated plants or to eliminate disease-carrying insects in specific areas. insecticide application.

In a dihybrid cross, round (RR), yellow (YY) seeds were crossed with wrinkled (rr), green (yy) seeds. What were the phenotypes o

Andrews [41]

The answer is

Let's first represent alleles:
R - a dominant allele for round seeds,
r - a recessive allele for wrinkled seeds,
Y - a dominant allele for yellow seeds,
<span>y - a recessive allele for green seeds.
</span>
The cross will look like this RRYY x rryy
So, all of the offspring will be heterozygotes (RrYy) with round seeds (Rr), yellow seeds (Yy).
