Assume that tall (represented by t) is dominant over short stature (represented by y) in corn. if a heterozygous tall plant is crossed with a short plant, show, using ratios the genotypes and phenotypes you would expect the seeds from this cross to produce a. genotypes b. phenotypes

a. 1 : 1

b. 1 : 1

Explanation:

In this case, a heterozygous tall plant (Ty) is crossed with a homozygous short plant (yy) - which we can deduce as the recessive alleles only exhibit themselves in the absence of the dominant alleles.

The resulting offspring would have the genotypes (refer to attached image):

Ty (Tall)

Ty (Tall)

yy (short)

yy (short)

The genotypic ratio would be - 1:1 (Ty & yy are the genotypes present)

and the phenotypic ratio would be - 1:1 (tall and short are the phenotypes present)

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.
