Answer: crossing over
during the process of fertilization, a sperm and egg join together to create a zygote. since a sperm had half the number of chromosomes and an egg has half the number of chromosomes, when they join together the zygote had a complete diploid set of chromosomes. the assortment of chromosomes and crossing over promotes genetic variation during the process of reproduction
Complete question:
If the recessive allele for cystic fibrosis is represented as c, classify the following genotypes as homozygous dominant, homozygous recessive, or carriers: CC,Cc, and cc. State which one has the phenotype of cystic fibrosis.
Answer:
CC - homozygous dominant
cc - homozygous recessive
Cc - carriers
cc will have the phenotype
Explanation:
Cystic fibrosis is an autosomal recessive disorder that affects the production of mucus in the body, primarily affecting the lungs and digestive system.
Because it is autosomal recessive, an affected individual needs to inherit 2 copies of the faulty gene. The presence of just one normal copy of the gene is sufficient not to cause the disease
In genetics, the dominant allele is usually displayed as a capital letter and the recessive as a small letter. Homozygous means someone has 2 copies of the same allele, heterozygous means they have different alleles. Therefore, CC - homozygous dominant, cc - homozygous recessive, and Cc - carriers. Only those with a cc genotype will be affected, as the presence of one dominant allele is enough to block the phenotype
Answer:
They occur when the Sun reaches its highest or lowest point in the sky.
Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks. People generally think of weather as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. ... Climate is the weather of a place averaged over a period of time, often 30 years.
If you're asking what 'controls' the cell, then that would be the nucleus. The king of the cell.
