In peas, yellow seeds (Y) are dominant over green seeds (y). If a yy plant is crossed with a YY plant, what ratio of plants in t

LenKa [72]

The ratio of yellow seed phenotype with green seed color seed offsprings will be 4:0.

Explanation:

Given that:

Dominant trait is Y (yellow seed color)

recessive trait is y (green seeds color)

cross between YY and yy, According Mendelian Genetics dominant trait will be seen in phenotype as it masks the effect of recessive gene.

Punnet square shows that:

Y Y

y Yy Yy

All the plants produced will be tall phenotype.

The yellow seed plant plants will be heterozygous i.e Yy

the phenotype ratio is 4:0

The genotype ratio is 4:0

The genotype of the offspring is Yy

phenotype is yellow colored seed plant.

Lotions applied during winter season moisturize the skin very quickly. What could be the reason for this?

MrRissso [65]

The right answer is D.

The absorption of molecules at the level of the skin is carried out by passive diffusion for the molecules of low molecular weight (lower than 400 Da), the skin being covered with a lipoprotein film rich in water by its stratum corneum, rendering it little-permeable.

This absorption may be variable according to factors related to the skin such as stratum corneum's thickness, the state of hydration, the presence of cutaneous lesions or individual variations.

External factors may also modulate percutaneous absorption such as contact time, iontophoresis or the presence of specific adjuvants.
