Well let’s draw a punnet square. So first make your four boxes. Now, heterozygous means having two different alleles of a particular gene. We’re going to use the letter ‘A’, but you can use any letter. In your first box there will be the dominant alleles. This can be identified as ‘AA’. A dominant allele is capitalized (A). A recessive allele is lower case (a). So in the first box it will be AA. Move over to the box on the right it will be Aa. Move down one box (on the right side) that will be aa. Now still on the bottom box, move over one to the left. That will be Aa. Since hetero means different, the heterozygous alleles would be Aa which means you have 2/4 probability of the child being affected. So 1/2.
Answer: Option A
Explanation:
Homosapiens also known as Herto Man. It is the name given to the number of the early modern human fossil which was found in the 1977 which was dated to be around 160,000 years ago.
Palaeoanthropologists determines the skeletal that was found belongs to the extinct species of homo sapiens that once lived in Pleistocene Africa.
The skeletal was dated using the potassium dating which helped to known the age of the fossil.
Scavenge dead matter on the ocean floor because many animals in this zone do not have eyes Use bioluminescence to lure prey because in total darkness prey will not be drawn to the light Use camouflage to blend into the seafloor because prey can be easily ambushed Produce their own food due to the lack of nutrients on the ocean floor.
False, Animal cells do “not” have cell walls.
