zhuklara [117]

Answer:

Explanation:

The plate were supposed to streak by D. radiodurans but unfortunately it was streaked by E.coli.

As there is no other petri plate available, this plate was exposed to the UV for the 30 minutes. The plate was not left uncovered and because of that the total E.coli could not die and another streak of D. radiodurans was done on the same plate.

As a result of incubation there will be growth of both of the organism in the petri dish.

A grow seeded purple flowered heterozygous plant (YyPp) is crossed with a green seeded, white flower plant (yypp). What is the p

vredina [299]

Question:

A yellow seeded, purple-flowered heterozygous plant (YyPp) is crossed with a green seeded, white-flowered plant (yypp).

(Y = yellow seed allele; y = green seed allele; P = purple flower allele; p = white flower allele)

What is the probability that an offspring of this cross produces plants with green seeds and white flowers? Assume the traits assort independently.

Answer:

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25

Explanation:

Available data:

Y = yellow seed allele; Dominant
y = green seed allele; Recessive
P = purple flower allele; Dominant

p = white flower allele; Recessive
the traits assort independently

Cross: A yellow seeded, purple-flowered heterozygous plant with a green seeded, white-flowered plant

Parentals) YyPp x yypp

Gametes) YP, Yp, yP, yp yp, yp, yp, yp

Punnett square)

YP Yp yP yp

yp YyPp Yypp yyPp yypp

F1) 4/16 = 1/4 = 25% YyPp, Yellow seeds and Purple flowers

4/16 = 1/4 = 25% Yypp, Yellow seeds and white flowers

4/16 = 14 = 25% yyPp, green seeds and purple flowers

4/16 = 1/4 = 25% yypp, green seeds and white flowers.

The probability that an offspring of this cross produces plants with green seeds and white flower is 25% = 0.25
