in their lifetimes, two guinea pigs produce 40 black pups and 40 white pups. On a seperate piece of paper, make a punnett square and find the likely genotypes of these parents.

The offspring inherits two alleles, one from each parent, that determine its appearance. The dominant allele determines the black fur color, while the recessive allele determines white fur color of guinea pig. We have several possibilities for the potential genotype of two guinea pigs: BB-BB, BB-bb, BB-Bb, Bb-Bb, Bb-bb, and bb-bb. When an offspring inherits at least one dominant allele, that will define the black color of its fur. The white color will appear only if the recessive allele is inherited from both of the parents. Therefore, we can conclude that in the genotype of the parental guinea pigs that give both black and white offspring, both of the parents must contain recessive allele, and at least one of them must have the dominant allele. However, since the ratio of black to white colored guinea pigs is 1:1, we can conclude that the most probable genotype in the parental generation is the following:

THANK MY ANSWER AND MARK ME AS BRAINLIST

you can't see the options

the water is warmed up by the sun and then it evaporates into the atmosphere. the sunlight warms the water by its heat. water is then cooled down and condensation takes place. the water then finally returns back to the earth by the process of precipitation in the form of rain or ice.
