Answer:

colorblindness

Explanation:

Colorblindness is a recessive sex-linked trait. ... Remember that in incomplete dominance, the two traits blend together; in co-dominance, the two traits are equally expressed; and in sex-linked traits, the traits can be dominant or recessive, but they always appear on the X-chromosome.

Answer: Color blindness

Explanation:

Color blindness is a sex related trait in which 99 percent of the people have a different visionary of red-green color. Most of the men are color blind and it has been seen that a very less number of women are found color blind if compared with men.

Whereas if the female is a carrier and the male is not affected the there are chances that the child born is suffering from color blindness.

This is a sex linked trait and X chromosome is usually carried from a mother to the son. So, the probability of the male being affected is more as compared to female.

Which of the following is not an observation or inference on which natural selection is based?

Sholpan [36]

Answer:

Option-(B): The following is not an observation or inference on which natural selection is based is the characteristics of a poorly adapted individuals which can never produce offspring.

Explanation:

The idea of natural selection basically follows the analyses of the heritable characters which passes from one generation into another, having the specific set of data or genome been transferred into there descendants. And how each specie goes through the process of survival in order to have more chances to acquire the required natural resources and shelter for them selves inside a region or area.

The Offspring produced by a cross between two given types of plants can be any of the three genotypes denoted by A, B, and C. A

ratelena [41]

Complete question:

The offspring produced between two given types of plants can be any of the three genotypes, denoted by A, B and C. A theoretical model of gene inheritance suggests that the offspring of types A, B and C should be in a 1:2:1 ratio (meaning 25% A, 50% B, and 25% C). For experimental verification, 100 plants are bred by crossing the two given types. Their genetic classifications are recorded in the table below.

Genotype Observed frequency

A → 18 individuals

B → 55 individuals

C → 27 individuals

Do these contradict the genetic model?

Use a 0.05 level of significance.

Determine the chi-square test statistic.

Answer:

Do these contradict the genetic model? No, according to the chi-square test, there is not enough evidence to reject the null hypothesis of the population being in equilibrium.

Explanation:

Available data:

Crossed genotypes: two
Genotypes among the offspring; Three → A, B, and C
Expected phenotypic ratio → 1:2:1
Total number of individuals, N = 100
A = 18 individuals
B = 55 individuals
C = 27 individuals

So, let us first state the hypothesis:

H₀= the population is equilibrium for this locus → F(A) = 25%, F(B) = 50%, F(C) = 25%
H₁ = the population is not in equilibrium

Now, let us calculate the number of expected individuals, according to their expected ratio.

4 -------------- 100% -------------100 individuals

1 --------------- 25% -------------X = 25 individuals A

2 -------------- 50% -------------X = 50 individuals B

1----------------- 25%--------------X = 25 individuals C

A B C

Observed 18 55 27
Expected 25 50 25
(Obs-Exp)²/Exp 1.96 0.5 0.16

(Obs-Exp)²/Exp

A) (18 - 25)²/25 = 49/25 = 1.96

B) (55 - 50)² / 50 = 25/50 = 0.5

C) (27 - 25)²/25 = 4/25 = 0.16

Chi square = X² = Σ(Obs-Exp)²/Exp

∑ is the sum of the terms
O are the Observed individuals: 2 in chamber B, and 18 in chamber A.
E are the Expected individuals: 10 in each chamber

X² = ∑ ((O-E)²/E) = 1.96 + 0.5 + 0.16 = 2.62

Freedom degrees = 2

Significance level, 5% = 0.05

Table value/Critical value = 5.99

X² < Critical value

2.62 < 5.99

These results suggest that there is not enough evidence to reject the null hypothesis. We can assume that the locus under study in this population is in equilibrium H-W.

During the absorptive state, metabolism adjusts to either provide energy for immediate use or store excess energy to be used lat

Effectus [21]

Answer:

A. Catabolic

B.Anabolic.

C. Anabolic

D. Catabolic.

E.Anabolic

F. Catabolic

G. Anabolic

H. Catabolic

Explanation:

Catabolic process is a metabolic processes that breakdown complex or larger molecules into smaller sizes by releasing energy.

The examples of such metabolic processes are;

Glucose is used as the primary fuel for energy

Dietary carbohydrate from a meal is digested and absorbed as monosaccharides, mainly glucose

Dietary protein from a meal is digested and absorbed as single amino acids.

Fatty acids are used as fuel sources for some tissues.

All this processes are catabolic processes because large molecules are broken to smaller ones and all this processes release energy.

Anabolic process is a metabolic process where smaller molecular are build up to form larger molecules and this requires the input of energy.

Examples are;

Glucose is used as the primary fuel for energy

Excess glucose is stored as glycogen in the liver and muscle.

Excess glucose is converted to fatty acids and stored as part of the triglyceride molecule in adipose tissue

Excess tatty acids combine with glycerol to form which are stored in adipose tissues.

All these processes requires the build up of smaller molecules to larger molecules and requires input of energy.
