Answer:
Option C, disruptive selection
Explanation:
Disruptive selection selects features and traits which are against the average population. The population would have extreme phenotypes but nothing in middle of that and hence could lead to deviation.
The higher percentage of male human population has deeper voice as dominant characteristics. The intermediate male population with a finer or less deep voice is small. As per the disruptive selection theory, the traits at the extremities are favored more over and above the mediocre traits and hence intermediate species (males with less deep or fine voice) will compete among themselves to produce species with ability on the extremes i.e deep voice or with higher level of testosterone.
Hence, option C is correct
Answer:
1/3
Explanation:
Let's assume that the allele "P" imparts purple phenotype to flowers while the allele "p" gives white phenotype. The self-fertilization of purple-flowered parent plants gave purple and white progeny in almost 3:1 (28:10) ratio. This means that the parent plants were heterozygous and the genotype of each was "Pp".
A cross between Pp and Pp produces progeny in the following genotype ratio=
1/4 PP: 1/2 Pp: 1/2 pp
So, out of total 3/4 purple progeny, 1/3 is homozygous for the purple allele (PP) while the rest 2/3 is heterozygous dominant.
