1. The phrase Darwin used to describe his broad theory of evolution is ''descent with modification.
2. All of life is related through common ancestry, accounting for the Unity.
When studying biology and involves more memorizing facts about organisms and how they live because
The genome is the complete set of genetic material in a cell or organism
Cells are the smallest unit of life. This is true.
Cells are important to the structure and function of living things. This is true.
All organisms are made of multiple cells. This is false, because there are many single celled organisms like bacteria.
Cells come in different shapes and sizes. This is true, as there are cells with a variety of shape and size (round shaped cocci and the elongated and flat bacillus). There are cells from squid's nervous system, called the neurons, that are comparatively very large in size than the vast majority of the other cells.
Answer:
Bb, Db
, Bd and Dd
Explanation:
When a cross between two parents (having certain trait) is carried out , they share their alleles with each other to produce offspring with new traits. These offspring have gentically different allele combination as compared to their parents. A genetic cross can be represented by a punnet square (as given below)
The cross between two parents with genotype "BD" and "bd" will result into the following offspring -
B D
b Bb Db
d Bd Dd
