Plants and animals that lack color are commonly called albinos. In corn plants, green (G) is dominant to albino (g). A student

Fittoniya [83]

(B) 25% GG, 50% Gg, and 25% gg

<u>Explanation:</u>

Given:

Green is dominant and is coded by G

Albino is recessive and is coded by g

Two corn plants that are heterozygous for color are crossed.

The heterozygous condition of the plant would be Gg.

The cross is shown in the table attached.

According to the punnett square drawn,

The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)

= 25% GG , 50% Gg , 25% gg

Phenotypic ratio = 3 : 1 ( green : albino)

= 75% green, 25% albino

The first trophic level

they would want to eat the primary producers, which are located at the first trophic level. due to the 10% rule only 10% of the energy from the previous trophic level is passed on.

A man and a woman are both carriers for two autosomal recessive disorders, PKU (chromosome 12) and cystic fibrosis (chromosome 7

ValentinkaMS [17]

Answer:

Pr= (3/16)

Explanation:

It was stated that both the man and the woman are both carriers for two autosomal recessive disorders, PKU (chromosome 12) and cystic fibrosis (chromosome 7).

∴ let Aa¹Bb° represent the traits in the Man

Where;

Aa¹ = carrier of PKU

Bb° = carrier of cystic fibrosis

Also, let Cc¹Dd° represent the traits in the woman

Where;

Cc¹ = carrier of PKU

Dd° = carrier of cystic fibrosis

Now, if Aa¹Bb° self-crossed, we'll have the F1 progeny as AB, Ab° , a¹B and a¹b°

also, if Cc¹Dd° self-crossed, we have CD, Cd° , c¹D and c¹d° as their F1 progeny

In the F2 generation, the dihybrid cross between the F1 generations will be:

AB, Ab° , a¹B, a¹b° × CD, Cd° , c¹D, c¹d°

ACBD, ACb°D, a¹CBD, a¹Cb°D

ACBd°, ACb°d°, a¹CBd°, a¹Cb°d°

Ac¹BD, Ac¹b°D, a¹c¹BD, a¹c¹b°D

Ac¹Bd°, Ac¹b°d°, a¹c¹Bd°, a¹c¹b°d°

Only (a¹CBD, Ac¹BD, a¹c¹BD) shows the probability that she will have PKU but not CF.
