Earth's gravity acts upon objects with steady force of 9.8 meter per second squared. Gravity is the attraction of earth acts on a body, that pulls it toward earth. The value of gravity is constant and equals to 9.8 m/s². The force of attraction can be calculated by:

F = ma

where, m is the mass and a is the acceleration due to gravity which is equals to g. The force of gravity is equals to the weight of the body and can be written as:

W = mg

If B represents the allele for black eyes (dominant) and b represents the allele for orange eyes (recessive), what would be the
Nuetrik [128]

Answer:

1 black : 1 orange

Explanation:

This is a typical monohybrid cross involving a single gene coding for eye color in MendAlien. The allele for black eyes (B) is dominant over the allele for orange eyes (b). In an heterozygous state, Bb i.e. combination of both dominant (B) and recessive (b) alleles, the MendAlien will be phenotypically black.

In a cross between a heterozygous MendAlien (Bb) and an orange-eyed MendAlien (bb), two of the offsprings will have a Bb genotype and be phenotypically black-eyed which the other two will have a bb genotype and be phenotypically orange-eyed. Thus, a phenotypic ratio of 2 Bb : 2 bb will be obtained.

This is also equal to 1:1 i.e. 1 black-eyed : 1 orange-eyed.
