"Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely

lyudmila [28]

Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"

A) complete dominance

B) incomplete dominance

C) codominance

D) epistasis

E) incomplete penetrance

Answer:

B) incomplete dominance

Explanation:

Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.

For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".

1. What are the end products of photosynthesis?

Firlakuza [10]

Answer:

1. Glucose And Oxygen.

2. Transpiration is the process by which water is lost in the form of water vapour by evaporation from the surface of leaves and other serial parts of plant .

3. A. Cooling Effect : The water keeps on evaporating from the leaf surface during transpiration . The heat required for evaporation of water is obtained from the plant itself and thus, the plant cools itself when it is hot outside.

B. Transpiration Pull : As water evaporates from the leaf surface, the roots pull up more water from the soil to make up for the water loss during transpiration .As a result, important mineral salts are also brought along with the water. These salts are necessary for the growth of the plant .

4. Leaf Tendrils : Sweet Pea

Spines : Cactus

Scale Leaves : Onion

5. Pitcher Plant, Venus FlyTrap, Blodderwort

6. Normally plants propogate with the help of seeds contained in the fruits . But some new plants may also be produced from other part of the plant such as the roots, stems, and leaves . This type of reproduction is called vegetative propogation .

E.g. = Bryophyllum .
