There are two different alleles for flower color, p and p. the image shows a purple sweet pea that is labeled with its two alleles for petal color.

which is the genotype of the sweet pea?
heterozygous dominant

heterozygous recessive

homozygous dominant

homozygous recessive

The genotype is homozygous dominant

It would be homozygous because they are both capitals. And capital letters mean it is dominant.

If one was a capital P and the other was a lowercase p then it would heterozygous.

Hope this helped :)

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
