The genetic defect most likely causes each leaf to lack a sufficient root system that can support the plant's growth.

The root system of plants contains networks of roots and their branches which functions by absorbing and transporting water and dissolved minerals from the soil to the plant in order to support the growth of the plant. They anchor (hold) the plant in the soil and also store reserve foods that can be used later by plants. Absence of sufficient root system in plants will affect the plants normal processes (including photosynthesis). The plant’s water absorbing capacity will be greatly reduced and this will make the plant to become dry (weak) and to be susceptible to insect and diseases.

Consider the following three populations of birds. Assume HW equilibrium. With these birds red coloring is recessive, while brow
bixtya [17]

Answer:

Red allele frequency will be highest in population II

Population III can undergo bottleneck effect

The frequency of the brown allele will  least likely be altered in the population I

Explanation:

Population I -

Total population - 670

Brown birds - 603

Red birds - 67

Population II

Total population - 100

Brown birds - 90

Red birds - 10

Population III

Total population - 30

Brown birds - 27

Red birds - 3

Frequency of red birds in population I

\frac{67}{670} = 0.1

Frequency of red birds in population II

\frac{10}{90} = 0.11

Frequency of red birds in population III

\frac{3}{30} = 0.1

Red allele frequency will be highest in population II and it will be equal to \sqrt{0.11} = 0.33 as compared to 0.31 in case of population I and III

Population III can undergo bottleneck effect because of smaller population size

The frequency of the brown allele will  least likely be altered in the population that has highest  brown individual , i.e population I

Using your knowledge of Punnett squares and hybridization, what is the probability that a purebred monohybrid, dihybrid, three-f
Nimfa-mama [501]

Answer:

100%

Explanation:

No matter how many factors are in the cross, if an 2 purebred (homozygous individuals) are crossed, (one dominant, one recessive) the dominant phenotype will always be displayed.

Imagine a cross with between two individuals true breeding for 6 traits. One shows all dominant genotypes, one shows all recessive genotypes. The only gametes those individuals can pass on will always produce heterozygotes.

AABBCCDDEEFFGG x aabbccddeeffgg

The first individual can only give ABCDEFG alleles. The second individual can only give abcdefg alleles. Therefore, all offspring will be AaBbCcDdEeFfGg, and will therefore express the dominant trait.
