2.13-Adduction- d) Latissimus dorsi
2.14- Ganglion- f) origin of nerve
2.15-Deuteranopia- a) color blindness
2.16 allosome- g) sex chromosomes
2.17autogamy- b) self pollination
2.18 dwarf pea plant-c) homozygous
Explanation:
- adduction means movement of limb and Latissimus dorsi muscle help in various movement like swimming, pull-up etc.
- collection of cell bodies in the peripheral nervous system is called ganglion. axons or nerve fibers are generated from cell body of neuron
- deuteranopia is a x Linked inheritance of color blindness. in this this individual have no green cone cells
- allosomes are also called sex chromosomes. where chromosomes other than sex chromosomes are called sex chromosomes
- autogamy means fusion of gamete coming from same individual. Also known as self pollination
- recessive gene t is required to express dwarfness . it require two copies of t gene to produce dwarf phenotype. they are homozygous as they carry two same type of allele.
