Answer:
Multiple alleles can modify the classical Mendelian ratio by increasing the number of phenotypes.
For example, in a monohybrid cross, Mendel gets only 2 phenotypes however, in ABO blood groups (a classical example of multiple alleles) there are four phenotypes present in a population.
Lethal alleles are the alleles which when expressed result in the death of an organism. These alleles can be dominant, recessive or conditional (depends on interaction with another gene).
Thus, lethal allele reduces the ratio of the phenotype associated with it by affecting the survival of the organism.
For example, lethal yellow allele in mice results changes the phenotype ratio from 3:1 to 2:1
Answer:
The correct answer will be- proteoglycans and the glycoproteins
Explanation:
The connective tissue forms a very large proportion of the total mass of a body. The connective tissue plays a distinct role in the body like the movement of the cell, mechanical support, wound healing but the main role is to connect different tissues of the body.
The property of the connective tissue is determined by the amount and type of the extracellular matrix present which contains three main components which are the fibres like collagen, glycoproteins and the proteoglycans.
Thus, proteoglycans and glycoproteins are the correct options.
