If we represent dominant trait (wrinkled seeds) with A and recessive trait (non-wrinkled seeds) with a, then genotypes are AA (dominant homozygous), Aa (heterozygous), and aa (recessive homozygous). The phenotype of wrinkled seed is determined by genotypes either Aa or AA. Since the cross of a plant with wrinkled seed with a plant with non-wrinkled sees gives only wrinkled-seeded offspring, the plant with wrinkled seeds must be dominant heterozygous.
Let's look at both examples.
If wrinked-seeded parent contains one non-wrinkled allele, it must be heterozygous (Aa):
Parents: Aa x aa
Offspring: Aa Aa aa aa
So, the 50% of offspring has wrinkled seeds and 50% has <span>non-wrinkled seeds.
If </span><span>the wrinkled-seeded parent does not contain any non-wrinkled allele:
</span>Parents: AA x aa
Offspring: Aa<span> Aa Aa Aa
</span><span>
Thus, al</span><span>l of the offspring are heterozygous and all of them have wrinkled seeds.</span>
Answer:
The short term effects of stress include pain, nausea, change in appetite, heartburn, constipation, and in some cases, diarrhea.
Long term effect of stress on the body and behavior include changes in one's eating habits and chronic pain. Another long-term effect of stress is acid flux.
Asides having negative effect on the body and behavior, stress can also have some negative effect on the brain such as increasing the risk of developing mental illness, killing of the cells in the brain, brain shrink, and it can hurt one's memory.
