The pure-bred plants, with two identical genes, used in the initial cross would now be referred to as
homozygous
heterozygous
genetic twin
who is regarded as the father of genetics ?
Bateson
Morgan
Mendel
the physical expression of a character is called
Morphology
phenotype
genotype
if different alleles are present in the same genotype then it’s called
diallelic
A trait or disorder determined by a gene on one of the sex chromosomes is said to be
sex-linked inheritance
autosomal inheritance
recessive inheritance
An individual inherits .... allele for each gene (character)
2
3
4
a person with these alleles ( TT ) is known to be
homozygous dominent
homozygous recessive
Mendel's Law of uniformity: When two homozygotes with different alleles are crossed, all the offspring in the F1 generation are
identical and homozygous
different and heterozygous
identical and heterozygous
Mendel's Law of Dominance states that
recessive allele will mask the dominant allele
recessive allele will be masked by dominate allele
both allele will show in the offspring
Mendel’s experiments that followed the inheritance of flower color or other characters focused on only a single character via
trihybrid cross
dihybrid cross
monohybrid cross
Rare Exception to mendel’s first law Occur when two allelic genes fail to separate because of
non disjunction in 1st meiotic division
non disjunction in 2ed meiotic divison
non disjunction in mitotic division
in autosomal dominant The trait (character, disease) appears
1st generation
2nd generation
all generations
in autosomal recessive the trait only shows itself in
The Inheritance Pattern of the sex linked inheritance is ………….. the autosomal inheritance
identical to
different from
usually the same
the condition exhibits itself whether dominant or recessive
hemizygous
