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:

Explanation:

THANK MY ANSWER AND MARK ME AS BRAINLIST

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

linnaeus is the father of taxonomy

explanation:

which is the system of classifying and naming organisms. one of his contributions was the development of a hierarchical system of classification of nature. today, this system includes eight taxa: domain, kingdom, phylum, class, order, family, genus, and species.
