A horticulturalist wants to produce geraniums with specific characteristics. She knows that the trait of red flowers is governed
LenaWriter [7]
That the Red flowers are a dominant trait, and the white flowers would be recessive.  

The Red Flowers are Homogenous Dominant
In a punnet square, The Genotype ratio for the red flowers would be 2:2 
The phenotype would be 4:0 

For the white flower 
The Genotype would be 1:1
and the phenotype would be 1:0 
The white flowers are Homogenous recessive

TP53 is a recessive gene and is not located on the X chromosome, why would people who inherit just one mutant copy of a recessiv
Umnica [9.8K]

Answer:

Explanation:

Since it is a recessive gene, tumor suppressor genes required the inactivation of both alleles, this is usually accomplished by the mutation of one allele and a targeted homozygous deletion of the second allele. This leads to an effective inactivation of the suppressor genes with the mutations acting a a dominant negatives. This way, patients are put at a higher risk of developing cancer

These bacteria rapidly divide until they run out of space. Their growth then slows down, and their population size stabilizes. W
Lana71 [14]

The correct answer is B. S-curve

Explanation

There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

nydimaria [60]

Answer:

A) 1:2:1

Explanation:

Incomplete dominance is an effect observed in the organisms in which the neither of the two alleles controlling a trait is dominant or recessive instead produces a phenotype formed by the mixture of the effect of the two alleles.  Therefore in incomplete dominance, a new trait is produced which is formed by both the alleles.

In the given question, if incomplete dominance is observed in a monohybrid cross which results in two homozygous genotypes and two heterozygous genotypes. In F2 the phenotypic generation produced will be 1:2:1 as the heterozygous genotype will form a new phenotype.

Thus, Option-A is the correct answer
