A trait that is always expressed when this gene is present is called adominant trait
recessive trait
prime trait
strong trait

Answers

Answer:

i think it is a recessive trait, i hope this helped.

Explanation:

Final answer:

A trait that is always expressed when a gene is present is called a dominant trait. Dominant traits only require one copy of a gene to be expressed. An example is brown hair, which, when paired with a gene for blonde hair (a recessive trait), will express as brown hair because it is dominant.

Explanation:

In the field of genetics, a trait that is always expressed when a particular gene is present is called a dominant trait. This type of trait only requires one copy of a gene — from either parent — to be expressed. For example, if one parent gives a gene for brown hair (a dominant trait) and the other for blonde hair (a recessive trait), the offspring will have brown hair. Brown hair is dominant because it is expressed even when only one gene for it is present.

Why it is important for meiosis to produce haploid cells

Answers

Meiosis is the reductional division which takes place in organisms which reproduce by the process of sexual reproduction. It produces haploid cells to maintain the chromosome number constant in the offpsring.

What is Meiosis?

Meiosis is a type of cell division which results in the reduction of chromosome number in the cell by half of its original number. Meiosis is also known as reductional division.

Meiosis takes place in the process of formation of gametes in the organisms which reproduce by sexual mode of reproduction. In meiosis, four daughter cells are produced, which are haploid. The male and female gametes produced by meiosis under fertilization to form zygote which is diploid. If the gametes were not haploid then the offspring will show presence of extra set of chromosome which can lead to chromosomal disorders.

Answer:

The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell. "Meiosis is reductional," said M.

Which of the following produce intrinsic factor?A. parietal cells
B. zymogenic cells
C. mucous neck cells
D. enteroendocrine cells

Answers

Parietal cells produce intrinsic factor, whereas zymogenic, mucous neck, and enteroendocrine cells do not.

Parietal cells produce intrinsic factor, which is important for the absorption of vitamin B12.

The correct answer to the given question is option A.

Intrinsic factor is a protein produced by parietal cells in the stomach.

It plays a crucial role in the absorption of vitamin B12 in the small intestine. Without intrinsic factor, vitamin B12 cannot be absorbed and can lead to a condition called pernicious anemia.
