In drosophila, proper anteroposterior and dorsoventral development requires a separate set of maternal effect gene products accu
rosijanka [135]

It is true. In drosophila, distinct sets of maternal impact gene products must accumulate in the proper region of the embryo to ensure proper anteroposterior and dorsoventral development.

<h3>What makes Drosophila unique?</h3>

The use of Drosophila over vertebrate models has many technological advantages;

  • they are simple and affordable to culture in lab settings,
  • have a significantly shorter life cycle,
  • produce huge numbers of externally deposited embryos
  • may be genetically manipulated in a variety of ways.
<h3>Why is Drosophila referred to be the genetic Cinderella?</h3>
  • Drosophila, which means "dew loving," is derived from the Greek word drósos.
  • Fruit flies, or Drosophila melanogaster, are referred to as the genetic Cinderella.
  • This term was given to them because of their 12-day lifetime, ease of culture, and ability to produce numerous offspring from a single reproduction.

Once sperm cells are mature and capable of fertilizing an egg they are stored for delivery in this part of the male reproductive
telo118 [61]
The answer is epididymis.
Epididymis is a tightly coiled mass of thin tubes that carries sperm from the testes to the ductus deferens in the ale reproductive system. Sperms matures as they pass through the epididymis so that they are ready to fertilize ova by the time they enter the ductus deferens.  During the ejaculation stage of emission sperms are moved from the testes and the epididymis, where they are stored, to the beginning of urethra.

Strike441 [17]
Myocardium, that's because myocardium simply means 'muscular tissue of the heart'. It is not pericardium or connective tissue as these are only small, specific areas of the heart and a heart attack can cause cells to die anywhere in the heart.

Tay-Sachs disease is a lethal, autosomal recessive genetic disorder. If both parents are heterozygous carriers of the disease, w
rjkz [21]

Answer:

50%

Explanation:

Let's assume that the allele "T" gives the normal phenotype while the recessive allele "t" imparts the disease and is lethal in homozygous condition. The genotype of each of the two carrier parents would be "Tt". A cross between Tt and Tt would give the progeny in the following genotype ratio=

Tt x Tt= 1/4 TT: 1/2 Tt: 1/4 tt

Therefore, 1/2 or 50% progeny would be the carrier for the Tay-Sachs disease.
