Two fruit flies that are heterozygous for body color and eye color are crossed. Brown body color is dominant to black body color
trasher [3.6K]

Answer:

This question is incomplete, the complete question is:

Two fruit flies that are heterozygous for body color and eye color are crossed. Brown body color is dominant to black body color. Red eye color is dominant to brown eye color. Use the Punnett square to determine the ratio of offspring with: Brown body and red eyes : Brown body and brown eyes : Black body and red eyes : Black body and brown eyes :

The answer is:

Brown body and red eyes : 9

Brown body and brown eyes : 3 Black body and red eyes : 3 Black body and brown eyes : 1

Explanation:

This question is a typical dihybrid cross involving two different genes. One coding for body color and the other for eye color. The allele for Brown body color (B) is dominant to the allele for black body color (b) in the first gene while the allele for Red eye color (R) is dominant to the allele for brown eye color (r) in the second gene.

In a cross between two parents that are heterozygous for the two genes i.e. BbRr × BbRr, each parent will produce the following possible allelic combinations of gametes:

BbRr- BR, Br, bR, and br

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced in the ratio 9:3:3:1 where the offsprings and their possible genotypes are;

Brown body and red eyes (B_R_): 9

Brown body and brown eyes (B_rr): 3

Black body and red eyes (bbR_): 3

Black body and brown eyes (bbrr): 1

Beginning with the flow phase arrange biochemical process in order menstrual cycle
Serga [27]

Explanation:

Menstrual cycle is a complex cycle that consists of several processes. Order of occurrence of steps in menstrual cycle are as follows:

1. High progesterone levels maintain the endometrium lining of the uterus.

2. Endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release FSH and LH.

3. FSH and LH stimulates the follicles to develop and the oocyte to produce estrogen.

4. Rising estrogen levels suppress FSH production and development of other follicles.

5. A spike in LH causes follicle to rupture.

6. A breakdown of corpus luteum causes progesterone level to drop.

I hope it's helpful!!

What is a reason for peer review?
ValentinkaMS [17]
Scholarly. Scholarly peer review (also known as refereeing) is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal, conference proceedings or as a book.

Why can foods such as pineapples, pickles and tomatoes be treated with temperatures less than 100?
ratelena [41]
<span>The reason why foods such as pineapples, pickles and tomatoes can be treated with temperatures less than 100 is because t</span>hese foods are highly acidic (pH<4.6) which provides a hurdle to microorganims.
Low-acid foods have pH values higher than 4.6, while a<span>cid foods have a pH of 4.6 or lower. They include fruits, pickles, sauerkraut, jams, jellies, marmalades, and fruit butters.</span>
