Answers:
- Mendelian inheritance states that traits are determined when offspring receive <u>alleles </u>for each trait from <u>Parents</u>.
Explanation:
As per Mendel, all the traits which are present in an offspring are determined by specific genes which exist in alternate forms called alleles. For example: The height of a plant is a trait which is determined by alleles T for tall height and t for small height of same gene. The organisms acquire these alleles from parents (one allele from each parent).
--------------------------------------------------------------------------------
- Traits can be <u>Dominant </u>which means they can be seen and are capable of masking a different trait.
Explanation:
Dominant trait means when only a single dominant allele for the trait in an organism is enough for the organism to depict the trait. For example: In pea plant, purple flower color is a dominant trait over white. So any plant who contains only one dominant allele for purple (allele P) will have purple flowers but all plants that have two pp alleles will have recessive trait i.e White flowers.
-------------------------------------------------------------------------------------
- Traits can also be <u>Recessive </u>which means they can be masked.
As mentioned in above example, white flower color of pea plant is a recessive trait. Recessive means that if a plant has one copy of recessive and one copy of dominant allele, the dominant allele will suppress or mask the effect of dominant allele. Example is the above case of flower color when a plant with genotype Pp will have purple but not white flowers.
-------------------------------------------------------------------------------------------
- Alleles are different versions of the same <u>gene </u>in an organism.
Alleles are just alternate forms of a gene. For example if a plant height is determined by a gene L, it has two forms capital L and small l which are alleles of same gene. But capital L is for tall height and small l is for short height.
