Answer:

EeWw

Explanation:

The allele for the earlobe is depicted as e while that of the hairline is w.

A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.

The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww

eeWW x EEww

During meiosis, each genotype will form gametes.

eeWW: eW, eW, eW, eW

EEww: Ew, Ew, Ew, Ew

These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:

eW x Ew

<u>offspring</u>

100% EeWw (see the attached image for the Punnet's square)

<em>The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline. </em>

DNA has two strands.If the sequence of the nucleotides of one strand was known,is it possible to use that information to determi

boyakko [2]

Yes. the nucleotides are A, T, G, and C. A and T pair up and G and C pair up. For instance, if your known strand is AGTCAG then the second strand would have to be TCAGTC. Also, if there is a U in the strand, it takes the place of T. so the original strand would be AGTCAG and the unknown would have to be UCAGUC.

_____ can be prescribed to therapeutically lower cholesterol levels.

maxonik [38]

Answer:

Niacin can be prescribed to therapeutically lower cholesterol levels.

Explanation:

Niacin, known as vitamin B3, is used to reduce the risk of heart attack or stroke in people with high cholesterol. Niacin has gained popularity in the last 50 years and is mainly used to raise the level of HDL (high density lipoprotein) cholesterol, also known as good cholesterol and lowering bad cholesterol levels.

However, niacin can cause health damage, so it should always be used with medical supervision.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla

blondinia [14]

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross
