The correct answer is B. The parents are heterozygous with polka-dot tails, so they both have Pp genotype. The combination of their genotypes (Pp x Pp) could produce 4 genotypes PP, Pp, Pp and pp. Therefore, there is 25% chance for a PP genotype, 25% for a pp genotype and 50% for a Pp genotype. The PP and Pp genotypes produce a polka-dot tail phenotype and the pp genotype produces a solid coloured tail phenotype. In conclusion, there is 75% chance for a polka-dot tail (25% for a PP + 50% for a Pp) and a 25% for a solid coloured tail phenotype (25% for a pp).
Correct option(s):
(b) This muskmelon plant's genotype for the fruit taste gene is ff.
(c) This muskmelon plant is homozygous for the fruit taste gene.
A dominant allele is one that is capable of expressing itself even in the heterozygous condition and overshadows the effect of the recessive allele. It is usually denoted by a capital letter. Recessive allele on the contrary cannot express in presence of a dominant allele and is denoted by a small letter.
In the given case the fruit with a sour taste (phenotype) can have two possible genotypes (FF and Ff). The genotype of sweet taste is ff which is a homozygous condition.
Note: Your question is incomplete, probably your complete question is “In a group of muskmelon plants, some individuals have sour fruit and others have sweet fruit. in this group, the gene for the fruit taste trait has two alleles. the allele F is for sour fruit, and the allele f is for sweet fruit. a certain muskmelon plant from this group has sweet fruit. this plant has two alleles for sweet fruit. Choose the correct option:
(a) this muskmelon plant's genotype for the fruit taste trait is sweet fruit.
(b) this muskmelon plant's genotype for the fruit taste gene is ff.
(c) this muskmelon plant is homozygous for the fruit taste gene.”

Answer:
The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.
Explanation:
Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.
