Answer:
78
Explanation:
Chickens have 78 chromosomes. They inherit 39 from each parent, therefore a zygote (which is made up of an egg and a sperm, each a haploid gamete with 39 chromosomes) will have 78 chromosomes.
This is more than humans: we have 46 chromosomes, as we inherit 23 from each parent.
Cells are the basic unit of life
Answer:
The diagram, which illustrates a form of genetic recombination, shows that each allele is granted separately to the daughter cells, which is an example of independent assortment.
Explanation:
Crossing over, fertilization and independent assortment are methods of genetic recombination. The diagram (image) states that A-a and B-b are alleles for different characteristics, found in genes and chromosomes.
Independent assortment it was observed for the first time by Gregory Mendel, during his experiments with peas, describing that alleles -the portion of genes that contains variations of specific characteristics- are unrelated to each other and can be distributed independently in the daughter cells.
In this case, thanks to independent assortment, each parent can pass the characteristics of their genotype separately to the offspring -which will have shared characteristics of both- producing genetic variation in species.
