inheritance Flashcards
what is dna
molecule that carries the genetic information to function and reproduction of organisms
what is chromosomes
highly coiled and carries many genes along its length rod-like structure
what are homologous chromosomes
a [pair of chromosomes one from male parent one from female parent and it is similar in size same seq of genes
what are alleles
alternative forms of the same genes which occupy the same relative position on a pair of homologous chromosomes
what is a penotype
expressed trait in an organism and results of genes and environment
what is a genotype
genetic make up of organism determined by combination of alleles
what is a dominant allele
it is capital letters gives the same phenotype in both homozygous and heterozygous conditions
what is a recessive allele
it is small letters,does not express itself in heterozygous condition and only in homozygous
what is a homozygous
for a trait of 2 alleles controlling trait is identical
what is heterozygous
for a trait of 2 alleles controlling trait is different
what is a homozygous dominant
homozygous for dominant allele TT
what is homozygous recessive
homozygous for a recessive allele tt
dominant trait
result of inheritance of dominant allele
recessive trait
results of inheritance of recessive allele
