In peas, the allele for yellow seeds (y) is dominant to the allele for green seeds (y). what would be the genotype and phenotype ratios of offspring from a cross between yy (heterozygous) and yy (homozygous recessive) individuals?
a. genotype: ½ yy : ½ yy; phenotype: ½ yellow : ½ green
b. genotype: all yy; phenotype: all yellow
c. genotype: ½ yy : ½ yy; phenotype: all yellow
d. genotype: all yy; phenotype: all green

A. Genotype: 1/2 Yy; 1/2 yy. Phenotype: 1/2 Yellow; 1/2 Green.

Explanation: The answer lies in Punnett´s Square. A visual representation of Mendelian inheritance. Dominant genes always express when an organism presents them. Recessive genes express when both alleles contain the recessive gene. A heterozygote contains different alleles for the same gene (Yy). A homozygote contains the same alleles for the same gene (YY/yy), which can be a Dominant (YY) or Recessive (yy) Homozygote.

Y  Yy | Yy

y   yy | yy

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.

here is your answer hope i .
