genes Flashcards
haploid
set of unpaired chromosmes, 23 chromosomes, gamete
diploid
cell with 2 complete sets, 46 chromosomes
genotype
letters, genetic constitution
homozygous
identical alleles (rr) (RR)
heterozygous
different alleles (Rr) (RW)
somatic cell
any cell that is not reproductive (body cells)
autosomal disorders
dues to mutations in genes
sex-linked disorders
can be carried sex to sex
gamete
sex cell
homologuouss chromosoes
one set from mom one from dad
number of cells produced in meiosos
4
number of chromosomes in meisois
46
beggening of meiosis
diploid
end of meiosis
haploid
produces
4 gamete cells
effects of errors in meiosis
will be abnormal some will be exact copies extra chromosomes
gregor mendel
“father of genetics” experimented wit pea plants found basic principles of genetics
incomplete dominance
one allele is not dominant to another and they blend ( 2 capital letters)
co dominance
both show to together reccesive and dominate both show together
sex linked
desribes sex specific patterns and inheiratance when mutation is present on a sex chromosome
chromosomes for males
x, y
chromosomes for females
x, x
