In 4 o'clock flowers, red is dominant to white, but the heterozygote is pink. What is the phenotype ratio of crossing red 4 o'cl
Ne4ueva [31]

Answer:

Phenotypic ratio = 1 Red : 1 Pink

Explanation:

This phenomenon exhited by the gene coding for flower colour in four o'clock plants is called INCOMPLETE DOMINANCE i.e. the red flower allele (R) is not completely dominant over the white flower allele (r), hence, a third intermediate pink phenotype (Rr) is formed in an heterozygous state. The red and white flowers will only be expressed in a RR and rr genotypes respectively.

In a cross between a red-flowered 4 o'clock plant (RR) and a pink-flowered 4 o'clock plant (Rr), the gametes:

R and R will be produced by the red-flowered plant while gamete R and r will be produced by the pink-flowered plant. Using this gamete in a punnet square, one will have four possible offsprings in which two will be phenotypically red-flowered (RR) and two phenotypically pink-flowered (Rr). i.e. 2RR:2Rr

Hence, the phenotypic ratio is 1:1 Red to Pink flower

A species of bird was well established on an island. Its beak was well-structured for cracking large nuts. After a few years, so
Nataly_w [17]
The birds adapted to the changes. Since the large nuts were no longer as abundant because of the large birds, the small birds were left with the smaller nuts. Their larger beaks lost their use since the small nuts did not require such well-structured beaks, so the birds started to develop smaller beaks.

Describe the role of the gametophyte and the sporophyte in the plant reproductive cycle.
Pavlova-9 [17]
After reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divide by mitosis to produce the haploid gametophyte. The new gametophyte produces gametes, and the cycle continues.
