Engineering HSC and IIT-JEE Main an
advance videos students today we are
studying chapter genetic basis of
inheritance in that we are studying
topic Hytrozygous when I say hetero it
means different now homozygous means
similar so does heterozygous means let's
study that today.
whereas a Heterozygous now hetero means
different
and when I say zygous it means a lease
or in normal terms we can says a lease
which are present on chromosomes and
heterozygous plant will have capital
T and small T for a particular trade
which is hike
I will confuse what is this heterozygous
and homozygous when I said homozygous
for a particular plant for example if
the plant is tall if it is having the
homozygous characteristics it will be
capital T capital T if the plant is
small that is it is homozygous Thor
plant then it will have small T and
small T as its set of gametes
if a plant is heterozygous hetero means
different then it will have a capital T
and a small T in it now Mendel crossed
all this varieties here cross a capital
T capital D with a small T small T that
is a homozygous power plant with a
heterozygous short plant or da friend he
also crossed in f2 generation and next
generation are heterozygous that is
capital T small T plant with a capital T
small T plant to see the results of
various generation to see what's the
variation that was also how different
laws of codominance dominance came into
picture was due to Mendel's this try or
this experiment if I put on the normal
definition of heterozygous then it could
be that if an individual is having two
different pairs of alleles for a
particular character or for a particular
trait then that individual or that plant
could be called as heterozygous or that
character could be called as a
heterozygous character we as human
beings also have heterozygous
characteristics and we as human beings
in by forget these heterozygous
characteristics from a parents they we
all know that some kind of characters we
inherit from a father some kind of
characteristics we inherit from a mother
sometimes the mixing match some of those
characteristics linked to the formation
of view as an individual who will have
certain heterozygous
characteristics certain good
characteristics from one set of parents
certain little not good characteristics
from another set of ends similarly when
Mendel crossed the heterozygous
characteristics what he observed was
that the dominant ones were always
pushing the recessive one's the dominant
ones were always powerful then the
recessive ones
heterozygous when I talk about
heterozygous it means different non
individual with two different alleles
for a given characteristic
is said to be heterozygous now this two
different alleles will be present on the
same locus or different locus on the
chromosomes we could have some on the
same locus and some on the different
locus as well as there's any chance that
if an individual is having a
heterozygous a live for a pair of food
chain of a particular characteristics
can the my particular disease may be in
humans
yes there are certain diseases that we
invite to do heterozygous
characteristics on heterozygous gametes
of cells now
Mendel's pea plant what heterozygous
meant was a capital T and small T now in
this heterozygous capital T was always
power plants so if there is a
heterozygous characteristics the plant
will always show at follow growth or the
plant will be just taller in phenotypic
appearance all when you notice the land
with your eyes the gland will be taller
students this was one of the definitions
that widely was observed or seen in
Mendelian genetics heterozygous now
homozygous heterozygous phenotype
genotype hybrids progeny theta all
linked and all the laws of dominance use
this words or use systems very
thoroughly and very often things I hope
Nala clear with this concept of
heterozygous time
