Question

what is heterozygous in biology ​

Answer 1

Answer:

Heterozygous is a state of having inherited different forms of a particular gene from each one of your biological parents. Now, by different forms we generally mean that there are different portions of the gene where the sequence is different.

Answer 2

ANSWER :-

• Heterozygous combinations of genes constitute of genotypes that are made up of a mixture of both, wild, original, non mutated, dominant genes, and mutated, recessive alleles.
• Heterozygous combinations are found in the progeny that are produced as a result of impure breeding or genetic crossing of pure-line parents.
• Only the wild, original, non mutated, dominant allele is able to express itself in phenotypes of such genotypic combinations.
• Examples of heterozygous combinations are as follows-
• In the context of height, Tt (Heterozygous tall), heterozygous combinations can never produce dwarf plants.
• In the context of eye colour Bb (Brown eyes), heterozygous combinations can never produce blue eyes.
