The probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.
<h3>WHAT IS A HETEROZYGOUS CROSS</h3>
A heterozygous cross is a cross between two individuals that are heterozygous for two genes.
According to this question, white (W) fruit color is dominant over yellow (w). If two white-fruited individuals with genotypes that are unknown are crossed i.e. Ww × Ww.
The offsprings of this cross are as follows:
Therefore, the probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.

Answer:
A vascular plant is any one of a number of plants with specialized vascular tissue. The two types of vascular tissue, xylem and phloem, are responsible for moving water, minerals, and the products of photosynthesis throughout the plant. As opposed to a non-vascular plant, a vascular plant can grow much larger.
Explanation:
Answer:
C. The chance of survival decreases when there is intraspecific competition for resources among surviving yearlings
Explanation:
The survival rate of the offspring of the fish species will decrease as a result of the huge number of eggs produced giving rise to overpopulation. Pressure will be on the limited available resources. As a result of this, Intraspecific competition would occur as members of the same fish species would compete for the limited resources.
Interference and exploitation competition are two types of Intraspecific competition that can reduce the population size of the fish species.
For Interference competition, the dominant and stronger members would secure adequate supply of the limited resources to detriment of the weaker and less dominant ones. This leads to the death of those members that are weak to compete successfully, thereby leading to a reduction in population size.
In exploitation competition, it involves all individual members of the fish species sharing the limited resources equally, while none of them gets an adequate amount. With time, a great size of the population decrease would be noticed when compared to that of Interference competition.
