Answer: chromatin condenses into chromosomes and can be best observed in prophase.

Explanation: chromosomes can’t be visualised by a light microscope except during cell division (mitosis or meiosis). The individual chromosomes become visible as the chromatin is wound tightly and are most clealry seen in late prophase.

Temperature affects spermatogenesis, which functions best at body temperatures just a little lower than those.

<h3>Abstract:</h3>

To keep testicular temperatures below those of the body core, adequate thermoregulation is essential. The process of mammalian spermatogenesis and the resulting spermatozoa are negatively impacted by elevated testicular temperature. Therefore, sperm quality can be affected and the likelihood of infertility is increased by thermoregulatory dysfunction resulting in heat stress. This article reviews a variety of internal and external factors that may lead to testicular heat stress. We go into more detail on how heat stress affects the spermatogenesis process, the resulting epididymal spermatozoa, germ cells, and the alterations that result in the testis.

We also go over the chemical reactions of germ cells to heat exposure and potential processes, such as apoptosis, DNA damage, and autophagy, that could lead to heat-induced germ cell damage. Further explanation is provided for the intrinsic and extrinsic processes involved in the complex mechanism of germ cell death. These intricate apoptotic pathways ultimately result in the demise of germ cells.

Mrac [35]

Answer:

The correct answer is -

a) 1/16

b) 1/64

c) 1/32

Explanation:

According to the law of independent assortment, each allele of a particular gene has equal chances of getting inherited into the gametes.

In a Mendelian cross of Aa x Aa would give;

AA = 1/4,

Aa = 2/4 and

aa = 1/4

The result of the cross between AaBb x AaBb would be 1/16 due to the fact that probability is still the same AA = 1/4, BB = 1/4 therefore, AABB = 1/16 = 1/4× 1/4.

Now based on this crossing the following:

AaBbCCDd x AabbCcDd.

Take each allele as individual

Aa x Aa would give; AA = 1/4, Aa = 2/4 and aa = 1/4

Bb x bb would give; BB = 1/2, bb = 1/2

CC x Cc would give; CC = 1/2, Cc = 1/2

Dd x Dd would give; DD = 1/4, Dd = 2/4 and dd = 1/4

Then the probability of progeny of the following would be:

a) the probability of AaBbCcDd = 2/4 x 1/2 x 1/2 x 2/4 = 1/16

b) the probability of aabbCCdd = 1/4 x 1/2 x 1/2 x 1/4 = 1/64

c) the probability of AabbCcDD = 2/4 x 1/2 x 1/2 x 1/4 = 1/32
