Question

C. In garden peas, one pair of alleles controls the height of the plant and a second pair of allele controls flower color. The allele for tall (T) is dominant to the allele for dwarf (t), and the allele for purple (P) is dominant to the allele for white (p). a. A tall plant with purple flowers crossed with a dwarf plant with white flowers produces 1/2 tall with purple flowers and 1/2 tall with white flowers. What is the genotype of the parents? TTYXttop b. A tall plant with white flowers crossed with a dwarf plant with purple flowers produces all tall offspring with purple flowers. What is the genotype of the parents? A tall plant with purple flowers crossed with a dwarf plant with white flowers produces 1./4 tall purple, 1/4 tall white, 1/4 dwarf purple and 1./4 dwarf white. What is the genotype of the parents? d. A tall plant with white flowers crossed with a dwarf plant with purple flowers produces 1/4 tall purple, 1./4 tall white, 1/4 dwarf purple, and 1.4 dwarf white. What is the genotype of the parents? e. A tall plant with purple flowers crossed with a a tall plant with white flowers produces 3/8 tall purple, 3/8 tall white, dwarf purple, and 1/8 dwarf white. What is the genotype of the parents? 8 A tall purple crossed with a tall purple produces 3/4 tall purple and 1.4 tall white. What is the genotype of the parents?

Answer 1

Answer:

a).

Tall, purple (TTPp) x dwarf, white (ttpp) ---Parents

	tp
TP	TtPp (tall, purple)-1/2
Tp	Ttpp (tall, white)-1/2

b).

tall, white (TTpp) x dwarf, puple (ttPP)---Parents

	tP
Tp	TtPp (tall, purple)

c).

Tall, purple (TtPp) x dwarf, white (ttpp) ---Parents

	tp
TP	TtPp (tall, purple)-1/4
Tp	Ttpp (tall, white)-1/4
tP	ttPp (dwarf, purple)-1/4
tp	ttpp (dwarf, white)-1/4

d).

Tall, white (Ttpp) x dwarf, purple (ttPp)—Parents

	tP	tp
Tp	TtPp (tall, purple)-1/4	Ttpp (tall, white)-1/4
tp	ttPp (dwarf, purple)	ttpp (dwarf, white)

e).

Tall, purple (TtPp) x tall,white (Ttpp)—Parents

	Tp	tp
TP	TTPp (tall, purple)	TtPp (tall, purple)
Tp	TTpp (tall, white)	Ttpp (tall, white)
tP	TtPp (tall, purple)	ttPp (dwarf, purple)
tp	Ttpp (tall, white)	ttpp (dwarf, white)

Tall, purple = 3/8

Tall, white = 3/8

Dwarf, purple = 1/8

Dwarf, white = 1/8

f).

Tall, purple (TTPp) x tall, purple (TTPp) ----Parents

	TP	Tp
TP	TTPP (tall, purple)	TTPp (tall, purple)
Tp	TTPp (tall, purple)	TTpp (tall, white)

Tall, purple = ¾

Tall, white = 1/4
