here the answer⤵⤵⤵

↪there are 3 laws of heredity proposed by Mendel↩

⭐làw øf sègrègàtîøñ
✒ Each inherited trait is defined by a pair of gene. Parental genes are randomly separated to the germ cells so that germ contain only one pair of genes.

⭐làw øf îndèpèñdènt àssørtmènt
✒ Genes of different traits are sorted separately from one another so that the inheritance of one trait is not dependent on the inheritance of another.

⭐làw øf døminànce
✒ An organism with alternate forms of a gene will express the form that is dominant.

Inheritance is the transmission of genetically controlled characteristics from one generation to the next.

Mandal studied the inheritance of characters or traits in various generation of pea plants cultivated by him.

1. ʟᴀᴡ ᴏғ sᴇɢʀᴇɢᴀᴛɪᴏɴ ᴀɴᴅ ᴍᴏɴᴏʜʏʙʀɪᴅ ɪɴʜᴇʀɪᴛᴀɴᴄᴇ.

Madel called the repressed trait as 'recessive trait' and the expressed traits of 'tallness' as the 'dominant trait'

The characteristics of an organism are determined by internal factors which occur in pairs only one of a pair of such factors can be present in a single gamet.

The two pairs of contrasting CHARACTER stove chosen by Mendel were shape and colours of seeds: round-yellow seeds and wrinkles-green seeds

round shape and yellow colour of the Sates world dominant traits over the wrinkled safe and green colour of the seeds.

the ratio of each type and the seeds of F2 generation is 9:3:3:1.

in the inheritance of more than one pair of traits in across simultaneously the factors responsible for each pair of traits are disturbuted independently to the gamets.
