Question

Mendel worked with pea plants that showed complete dominance for several traits. He was able to check his hypotheses about how inheritance works. He determined that traits are caused by two (? ) factors - one from the mother and one from the father.

?= form of allele that will mask the recessive

?= form of allele that will not show unless both alleles are recessive.

?= sections of a chromosome that code for proteins (and show up as traits).

?= both alleles have the same form = alleles are two different forms

?= forms of a gene

?= the alleles (genes) the organism has

?=the expression of the genotype (often an appearance)

?= crossing an organism showing dominant trait with a homozygous recessive to see if the dominant trait is homozygous or heterozygous

?= a cross involving one set of alleles

?= a cross involving two sets of alleles

Answer 1

He determined that traits that are caused by two contrasting factors for eg. Tall ( T) and dwarf (t)

Dominant form of allele mask the recessive

Recessive allele do not show expression unless both are recessive.

Genes are the sections of a chromosomes that code for protein.

In Homozygote both alleles have same forms

In heterozygote both alleles are of different forms

DNA forms a gene.

Phenotype the expression of genotype.

Test cross

Monohybrid cross

Dihybrid cross
