Eye colour in certain cat species is determined by a gene with multiple alleles. Brown eyes (CW) are dominant to green eyes (C N ) which are dominant to grey eyes (C Y ) which are dominant to blue eyes (C B ). A. List all the possible genotypes of a brown eyed cat. (1 mark) B. List all the possible genotypes of a grey eyed cat. (1 mark) C. Show the chances of obtaining a green eyed cat from the cross CWC Y x C N C Y using a Punnett Square.

it's     c       this is a cell (b) with a nucleus (c) containing dna (a). the dna is organized into chromosomes (d). a section of the chromosome that codes for a trait is called a gene (e).

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

we are putting to many trash.
