Scorpion4ik [409]
I think the correct answer would be mass of the shells. According to the law of conservation of mass, mass can never be created not destroyed. Therefore, mass here should be constant before the transformation and after the process. Hope this helps.

A population of wolves migrates north in search of food. as the wolves travel, they enter a region that has long, snowy winters.
Nookie1986 [14]
This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.

Mendel studied seven traits in pea plants. One of the monohybrid crosses he made was between plants with round seeds and plants
Finger [1]

Answer:

A. The dominant factor, or allele, is for round seeds.

Explanation:

Gregor Mendel discovered the principles that governs inheritance. During his numerous experiments, he conducted a cross in pea plants involving a single character. This cross is called MONOHYBRID CROSS. In one of these monohybrid crosses, he observed the gene for seed shape in pea plants. He discovered that two alleles are responsible for the expression of this gene: round allele (R) and wrinkled allele (r).

He crossed plants that produced only round seeds i.e. homozygous RR and plants that produced only wrinkled seeds, rr. He observed that the F1 offsprings were all round-seeded. This made him to propose his LAW OF DOMINANCE, which states that an allele is capable of masking the expression of another in a gene. He concluded that the round allele is covering the wrinkled allele in a heterozygous state, since it is expressed over it. He then called the round allele, DOMINANT allele and the wrinkled allele, RECESSIVE allele.
