1)A homozygous tomato plant with red fruit and yellow flowers was crossed with a homozygous tomato plant with golden fruit and white flowers. The F1 all had red fruit and yellow flowers. The F1 were testcrossed by crossing them to homozygous recessive individuals, and the following offspring were obtained:
Red fruit and yellow flowers41
Red fruit and white flowers7
Golden fruit and yellow flowers8
Golden fruit and white flowers44
How many map units separate these genes?
A)17.6
B)17.1
C)15
D)18.1
2)Which of the following, if damaged, would most directly hinder RNA polymerase from attaching to the beginning of a gene?
A)introns
B)exons
C)UTR's (untranslated regions)
D)snRNA
E)promoter region

Respuesta :

A purebred tomato plant with red fruit and yellow flowers was crossed with a purebred tomato plant with golden fruit and white flowers, and the map distance is 15, which is in option C. If the promoter region is damaged, RNA polymerase can't bind, which is in option E.

What is the map distance?

The map distance indicates the distance between two genes that are present on the chromosomes, and when the map distance becomes more than 50%, it indicates the two genes are present on different chromosomes. Here, the red fruit and white flowers and the golden fruit and yellow flowers are recombinants, while the other two are wild types.

Hence, the map distance is 15, which is in option C, and if the promoter region is damaged, RNA polymerase can't bind, which is in option E.
