Answer: Phenotype ratio is two heterozygous round pea : two homozygous wrinkled pea

Probability of getting a wrinkled pea is 1/2

The number of flowers that are homozygous is 2

The probability of getting a round pea is 1/2

Genotype ratio = 2 Rr : 2 rr

Explanation: From the information provided, round pea R is dominant while wrinkled pea r is recessive. A monohybrid cross between a heterozygous round pea Rr and a homozygous wrinkled pea rr will produce four offsprings, two of which are heterozygous round pea Rr and the other two are homozygous wrinkled pea rr.

The genotype ratio is 2 Rr : 2 rr while the phenotype ratio is two heterozygous round pea : two homozygous wrinkled pea. Heterozygous round (Rr) peas will manifest outwardly as round pea because R is dominant while r is recessive.

Since two out of the four offsprings are homozygous wrinkled pea, therefore the probability of getting a wrinkled pea is 2/4 = 1/2. Also, two out of the four offsprings are heterozygous round pea, therefore the probability of getting a round pea is 2/4 =1/2.

Since, only the two wrinkled peas are homozygous, therefore the number of flowers that are homozygous is 2

TEA [102]

The question is incomplete as it misses the options which are:

Cancer cells do not exhibit density dependent inhibition

Cancer cells do not require growth factors

Cancer cells do not exhibit anchorage dependence

Cancer cells ignore typical cell cycle checkpoints

Answer:

The correct answer will be option- Cancer cells do not exhibit anchorage dependence

Explanation:

A cell becomes tumour forming cell or cancerous cell when the cell undergoes some mutation in the DNA which causes uncontrolled cell division without differentiation.

As a result of the mutation, these cancerous cells show various properties which are present in the normal cells nut absent in cancerous cells like the cancerous cells lack the anchorage dependence.

Anchorage dependence is the property of the cells or the group of cells in which the cells maintain their adherence to the other layer of cells to communicate with each other.

Thus, the cancerous cells lack the anchorage dependence
