A one-year simulation is run with the settings shown below. The resulting yield was 6.6 tons per hectare, or 44% of the maximum
yield. What is the most likely cause for the poor yield?

Answer:
Option A, B, and C are correct
Explanation:
Incomplete dominance means that the trait represented by two alleles expresses themselves equally thereby hindering dominance of any of the allele completely.
Now,
Let us assume the allele of red petals be represented by "R" and the allele of white petals be represented by "r"
The pink flowers will have genotype "Rr"
Now if two pink flowers are crossed, the following offsprings are produced
Rr X Rr
RR, Rr, Rr, rr
Let us evaluate all the options one by one
a) Ration of pink flower to red flower ( Rr:RR)
There are 2 pink (Rr) flower and 1 Red (RR) , thus the ration of pink flower to red flower is 2:1. Option A is correct
b) one out of four offspring is white in color, therefore the % of white flower is
%. Option B is correct
c) Two pairs RR and rr are homozygous, thus out of four offsprings two are homozygous. Therefore %of homozygous flowers will be
%. Option C is correct
d) There are two heterozygous offsprings i.e Rr, therefore the % of heterozygous is %. Option D is incorrect
e) half of the flowers are hybrid. Therefore option e is incorrect
Therefore, Option A, B, and C are correct
Answer:
50% of their children are likely to be carriers of cystic fibrosis
Explanation:
Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, <u>the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF"</u>. The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.
