How do scientist predict the patterns of heredity?
Nookie1986 [14]

Answer:

The classic tool to predict the patterns of heredity is using a <u>Punnett Square</u>.

Explanation:

In genetics, a trait can be considered dominant or recessive. Since the important discoveries of Gregor Mendel, scientists use a <u>capital letter (D) to indicate a trait is dominant, and a lowcase letter (d) to show a trait is recessive. </u>

Assuming that a scientist knows the genotype for the desired trait they want to predict on the offpsring, a Punnett Square is<u> a reliable tool and a graphic representation that permits them to visualize the potential features of the offspring by showing how the alleles may be exhibited and passed on the offspring and will determine the possible combination of genotypes.</u>

<em>How does it work?</em>

For example, as we can observe in the image below, both parents are homozygous for a trait <em>PP=Purple; pp=white</em>. P is dominant and p is recessive (the color purple will be dominant, and the white will be recessive). So, we put one parent's genotype in the top row (PP) and the other parent's genotype in the left column (pp) and combine one of each letters on the squares, <em>i.e</em>. one of each parent's alleles. Then, we can observe in the results that 3 of the offspring will exhibit the purple color (PP, Pp, Pp) and only one will exhibit the white recessive color (pp); or more properly known as a genotypic ratio of 3:1.

Which of the following statements correctly relates mutations and survival rates of plants?
kiruha [24]
The third one is the right answer.
Mutations appear randomly and these mutations can either have possitive, negative or neutral impact on the individual's survival. The environment of the individual amongst other factor determine the net effect of the mutation. For example:
A mutation on a shade plant for bigger leaves would have a possitive impact on the plants survival due to the increase of the photosynthetic tissue area. On the other hand the same mutation on a desert plant would have a negative impact on the plant's survival due to the increase of the leaf area which leads to increased water evaporation off the plant.
