What is the probability of producing a white rose when a red rose is crossed with a pink rose?

Answers

Answer 1

Answer: A white rose cannot be produced in the G1 (first generation) of roses because the red rose will have a RR (R standing for red) allele combination. The pink rose will have a RW (R for red, W for white) allele combination. When crossed all combinations will have at least one R allele, meaning that no roses (in the first generation) will have a WW allele combination. WW is the only allele combination that produces white roses.

In humans tongue rolling is dominant to the inability to tongue roll. If a heterozygous tongue roller and a non-tongue roller have a child, what are the chances the child will be a non-tongue roller? A. 0 B. 0.25 C. 0.5 D. 0.75

Answers

Answer:

The chances of a child being non - tongue roller is $0.5\n$

Explanation:

Let the allele for dominant "tongue rolling trait" be represented by "T"

The allele for recessive "non-tongue rolling trait" be represented by "t"

The genotype of a heterozygous tongue rolling parent will be "Tt"

The genotype of a homozygous non- tongue rolling parent will be "tt"

If a cross is carried out between these two individuals , the offspring produced are as shown in the punnet square below-

T t

t Tt tt

So the number of offsrpings which are non- tongue roller are two in numbers represented by "tt"

So the chances that a child will be a non-tongue roller are

$(2)/(4) \n= 0.5\n$

Where , "4" represents the total number of offsprings produced

In humans, tongue rolling is dominant to the inability to tongue roll. The chances a child will be a non-tongue roller is C. 0.5.
