In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrin

meriva

Assuming the genes are not linked nor interacting with each other, the expected number of long stemmed plants with purple flowers, producing wrinkled peas, L-P-rr, is 288.

<h3>Available data</h3>

long stems are dominant to short stems
purple flowers are dominant to white,
round peas are dominant to wrinkled

Each trait is determined by a single, different gene.

A heter0zyg0us plant is self-crossed
F1) 2,048 descendants

Let us name te alleles as follows

L ⇒ Long stem
l ⇒ Short stem
P ⇒ Purple flowers
p ⇒ white flowers
R ⇒ Round peas
r ⇒ wrinkled peas

Cross) heter0zyg0us plant is self-crossed

Parental) LlPpRr

Gametes) LPR, LPr, LpR, Lpr, lPR, lPr, lpR, lpr

Assuming that these genes are not linked nor interacting with each other, to make the calcs easier we will make crosses considering each gene separately.

Stems

Parental) Ll x Ll

F1) 1/4 LL, 2/4 Ll, 1/4 ll

3/4 long stem, 1/4 short stem

Flower color

Parental) Pp x Pp

F1) 1/4 PP, 2/4 Pp, 1/4 pp

3/4 purple flowers, 1/4 white flowers

Peas

Parental) Rr x Rr

F1) 1/4 RR, 2/4 Rr, 1/4 rr

3/4 round peas, 1/4 wrinkled peas

Now, we will get the proportion of individuals with long stems, purple flowers, producing wrinkled peas, L-P-rr

Note: The symbol - is representing either a dominant or a recessive allele.

From the crosses, we know that

3/4 are long stemmed,
3/4 have purple flowers, and
1/4 have wrinkled peas.

To get the proportion of individuals expressing all these traits together, we just need to multiply these values.

3/4 L- x 3/4 P- x 1/4 rr = 9/64 L-P-rr

Knowing that the total number of plants is 2,048 and that there are 64 possible gametes combinations from this cross, we will use the proportion 9/64 to get the number of plants with these traits.

64 ------------- 2,048 plants

9 -------------- X = (9 x 2048) / 64 = 288 plants.

We expect to find 288 long stemmed plants with purple flowers, producing wrinkled peas.

Can someone please write a paragraph that explains what turbidity, cause I don't understand.

artcher [175]

Turbidity is the cloudiness or haziness of a fluid caused by large numbers of individual particles that are generally invisible to the naked eye, similar to smoke in air.

Two individuals from two different countries are having a conversation about marine organisms. The first person is trying to nam

Diano4ka-milaya [45]

The use of scientific name, which follows the rules of a standardized classification system.

<h3>Scientific classification of organisms</h3>

The scientific classification of organisms is known as the taxonomy. This system is used to categorise organisms into seven main divisions which include:

Kingdom,

Phylum or Division,

Class,

Order,

Family,

Genus,

Species

This system of naming organisms is accepted internationally. If the first person that named the killer whale used the scientific name which is Orcinus orca, the second person would have understood better.

What is the condition in which the inner layers of arteries become irregular and thick due to the accumulation of plaque?

Sliva [168]

Answer:Atherosclerosis

Explanation:

It is the condition in which the patcy deposits of the fatty materials forms in the walls of the medium sized and large arteries which reduces the blood flow in the artery.

It is the problem associated with the people eating more fatty food. The cholesterol of such people also increases and having a blockage can be dangerous sign as it can lead to heart attack at later stages.
