Svetradugi [14.3K]

In this case, the black body colour is the dominant one. The white dog is  homozygous recessive.

As the cross between the black female and the white male results in four white and three black pups. This means that the all the black offsprings are heterozygotes, and the white ones are homozygous recessive and the Female 2 have a dominant and 1 recessive gene, and is a hetrozygotezygous recessive having a Bb phenotype (where B codes for dominant allele and b codes for recessive allele).

Define mass and explain how it affects an object's density.
Klio2033 [76]

Great Question! Mass is basically how heavy Something is. Most people confuse mass with weight but there very different from each other. Weight is the downward force something has because of gravity. Mass can be measured in a variety of units too. The second part of the question is how it affects density. It affects it because to find the density you need to be able to find the mass since the formula is Mass divided by volume. I hope this helped you understand a little bit more about mass. Have a great day!
