Imagine an instance where there are two parents, and both have polydactyly, a trait which is determined in this example by a sin
1 answer:
The probability that their next child will have polydactyly is 0.75
<h3>What is Polydactyly?</h3>Polydactyly may be characterized as a circumstance in which an individual has more fingers or toes as compared to normal.
In humans, it occurs due to the homozygous mutants for a HOXD13, and due to which digits are joined and a condition known as Polysyndactyly occurs.
If both parents carry the genotype heterozygous for Polydactyly, i.e. Pp, the resultant offspring will have the genotypes PP, Pp, Pp, and pp. In which pp is normal, while all the three are affected due to the expression of dominant allele causing Polydactyly.
Now, according to the question, only one of the offspring possess the genotype of pp, hence the probability of their next child will have polydactyly is = 0.75.
Therefore, the probability that their next child will have polydactyly is 0.75.

Answer:
<u>1. ATP - decrease </u>
<u>2.NADPH - decrease </u>
<u>3. sugars - decrease </u>
And <u>True- Both ATP and NADPH are needed to make sugars.</u>
Explanation:
Photosynthesis is a form of biosynthesis that produces glucose from the reactants; it uses energy from sunlight, along with carbon dioxide and water. It happens in the chloroplast in two phases; the light-dependent and dark reactions. In the light reaction, solar energy stimulates photosystems, formed from pigments like chlorophylls.
Chlorophyll forms photosystems of proteins known as complex proteins (PS I & PSII). PS II absorbs and moves the reaction center with light energy.
- H+, and oxygen, are formed from a water molecule as it's broken apart.
- From photosystem II, electrons are transferred to photosystem I.
- ATP is synthesized from ADP along with inorganic phosphate.
- To form NADPHH, H+ is added to NADP
If PS II no longer works, there will be less ATP, NADPH, (both used later on) and no sugars produced.
In the dark reaction, products of the light reaction are used to make sugars. Here, in the Calvin cycle, the enzyme, RuBisCO, catalyzes the fixation of <u>CO2 with Ribulose 1,5-bisphosphate </u>(RuBP).
